Through more than 20 years of effort, China’s chemical engineering equipment has achieved significant technological advancements. However, compared with foreign countries, there are still significant gaps in China’s chemical processing equipment. The main issue is the disconnect between advancements in chemical production technology and the development of related equipment technologies; there is also a large gap in the development of software for such equipment. Equipment technology development fails to keep up with the pace of progress in process technologies, resulting in an emphasis on processes over equipment ； It remains largely at the stage of imitation-based development, with a weak capacity to develop proprietary technologies with independent intellectual property rights ； Equipment development has not yet achieved specialization or serialization ； The level of equipment design and manufacturing, as well as the quality and reliability of the equipment, still need further improvement. With the progress and development of chemical processing technologies, higher demands are placed on chemical processing equipment. It is necessary to intensify efforts in the development of such equipment, master its core technologies, and create a range of devices with independent intellectual property rights. Only by ensuring that these devices feature advanced performance, reliable quality, high efficiency and energy savings, as well as economic viability and safety, can the needs of the chemical industry be met. Chemical processing equipment is mainly divided into four categories: chemical unit equipment, specialized non-standard chemical equipment, general mechanical equipment, and instruments and meters. The various development aspects are as follows: 1. Chemical unit equipment. Chemical unit equipment mainly includes separation and filtration equipment, drying and evaporation equipment, mixing equipment, stirring equipment, heat exchange equipment, and extrusion granulation equipment, etc. 1.1 Separation and filtration equipment: Filters are devices that utilize porous filtering media to retain the solid particles in a mixture of liquid and solid particles, thereby achieving separation between solids and liquids. Primarily used in refineries for the separation of oil and wax, such as the cyclohexane dewaxing drum vacuum filter and the PTA plant vacuum drum filter. Currently, abroad, rotary drum vacuum filters are evolving toward larger sizes, higher speeds, greater precision, and full automation. In China, the design and manufacturing technologies introduced from the Italian company EIMCO were adapted, improved upon, to develop a complete set of processing, assembly, and welding techniques. In contrast, the main gaps lie in insufficient understanding of market development and product demands, low innovation capabilities, and poor ability to absorb the essence of imported technologies. Centrifuge: A centrifugal separator is a machine that uses centrifugal force to separate the various components in mixtures of liquids and solid particles, or of liquids with each other; it is also known as a centrifuge. There are mainly vertical and horizontal screw-discharge sedimentation centrifuges. Centrifuge technology abroad has developed rapidly, and it has become more specialized and diversified ； The domestically developed El-type LWFl000-N and LWFl050-N centrifuges have been used respectively for the separation of suspensions in high-density polyethylene plants with capacities of 70,000 to 100,000 tons per year. The LWl200x1980 type centrifuge developed has been used for the dewatering of PTA slurry in plants with a capacity of 225,000 tons per year, and the diameter of its drum reaches φ1200mm. However, vertical centrifuges are still in the initial stage of imitation, and the main gaps compared to foreign ones lie in design technology, as well as in the scaling up and serialization of products. 1.2 Drying and evaporation equipment Drying equipment: It is mechanical equipment that uses heating to vaporize and remove the moisture (usually referring to water or other volatile liquid components) from materials, thereby obtaining solid materials with a specified moisture content. The manufacturing diameters of Mitsubishi Heavy Industries Shipbuilding in Japan, Tsukishima Machinery, and FAUVET-GIREL in Germany exceed φ4000mm. The 200,000 tons/year HDPE steam pipe rotary dryer and the 400,000 tons/year TA plant steam pipe rotary dryer have been localized. The gap mainly lies in the larger scale of equipment; for the large-scale dryers in the upcoming polyethylene and polypropylene plants with capacities of 400,000–500,000 tons per year, as well as the 600,000-ton-per-year polyester plant, technologies still need to be developed in China. 1.3 Mixing Equipment Mixing equipment is machinery that uses mechanical force and gravity, among other means, to uniformly mix two or more materials together. They are divided into four categories: mixers for gases and low-viscosity liquids, mixing equipment for medium to high-viscosity liquids and pastes, mixers for thermoplastic materials, and mixing equipment for powdered and granular solid materials. Mitsubishi Electric has recently introduced the new FX2N-5A hybrid converter. The technology of domestic mixing equipment needs to be improved. 1.4 Heat exchange equipment Heat exchange equipment is an important type of equipment in chemical production; almost all chemical processes involve heating, cooling, or condensation steps, which makes it a crucial device for energy savings as well. With the enlargement and increased efficiency of industrial units, heat exchangers abroad are also becoming larger, evolving toward lower temperature differences and lower pressure losses. Plate-fin heat exchangers (cold boxes): Cold boxes are primarily used in ethylene cracking, air separation, and natural gas liquefaction. The key technologies involved are design and manufacturing techniques; companies such as the American company S-W and the German company Linde have relatively advanced and mature technologies in this area. Hangzhou Oxygen Generator Factory has introduced key processing equipment from the United States – large vacuum brazing furnaces – which have enabled the design quality and manufacturing capabilities of cold boxes to approach and reach international advanced levels; these furnaces have been used in the renovation projects of ethylene plants in Yanshan, Yangzi, Shanghai, and other locations. Foreign countries already have 9.0 MPa cryogenic tanks, while China has not yet mastered the design and manufacturing technology for high-pressure cryogenic tanks, and there is a significant gap in fractional condensation and distillation technologies. Plate-and-shell heat exchangers: Only the French company Packinox is capable of producing those used in catalytic reforming and hydrogenation units, with a maximum heat exchange area of 8000 m2. The largest heat transfer area developed domestically is 3000 m2; the main difference lies in the fact that although the area of each individual chip is the same, the heat exchange area is smaller. 1.5 Extrusion granulation equipment Extrusion granulator: This equipment enables the production of polyolefin pellets from polymers through processes such as mixing, extrusion, and granulation, to facilitate transportation. Abroad, only a few companies such as WP in Germany and Nippon Steel Corporation possess the capability to design and manufacture complete sets of large-scale mixing and granulation machines, with the mainstream trend moving toward twin-screw mixing and granulation units. The development pace in our country is relatively slow; at present, most of the machines developed and manufactured are of medium and small scale. After undergoing operational testing, the ABS mixing and extrusion machines with a capacity of 10,000 tons have met the design requirements in terms of their key technical specifications. At present, all extrusion granulators in large and medium-sized polyolefin production facilities rely on imports. 2. Specialized chemical processing equipment Specialized chemical processing equipment mainly includes reactors, towers, tanks, vessels, and other reaction devices. 2.1 Kettles Large-scale polymerization kettles: Abroad, the technology related to stirrer-equipped reaction kettles is quite advanced, and various stirrer designs can be developed based on different materials and parameter sets. The largest polymerization reactor successfully developed in China is the 90 m3 reactor used in the 70,000 tons/year high-density polyethylene plant. For the 100,000 tons/year polyester reactor, reaction rate models and process models for both the esterification and polycondensation steps were developed. Process technology software, as well as details regarding the structure of the reactors and their heat transfer requirements, were established. The esterification and polycondensation reactors developed by Yizheng Chemical Fibers have been put into operation. The main gap compared to foreign countries is the limited variety of mixers and weak capability in selection. 2.2 Towers The main functions of towers in petrochemical processes include distillation, absorption, stripping, extraction, washing, recovery, regeneration, dehydration, as well as gas purification and cooling. Commonly used types are tray towers and packed towers; abroad, improvements in tower design focus mainly on tray and packing technologies. Over the past 20 years, China has developed many plate and packed towers with excellent performance, which have been widely used in petrochemical and refining plants, and their performance is at an internationally advanced level. The representative types include DT trays suitable for handling high liquid fluxes, swirl trays suitable for handling high gas fluxes, three-dimensional mass transfer trays with high operational flexibility and efficiency, as well as sieve-plate and packing composite towers. The vacuum distillation columns of large plate-type and large packed-type designs installed at the 5 million tons per year lubricant-based refineries in Luoyang and Daqing have a diameter of φ8400 mm, while a large distillation column with a diameter of φ10000 mm, developed in China, is about to be put into use. Large-scale fertilizer ammonia synthesis towers: Internationally, representative ones include the Kellogg horizontal synthesis tower, the Topsoe vertical synthesis tower, the Wood vertical synthesis tower, and Brown’s three adiabatic axial synthesis towers. In China, on the basis of digestion and absorption of foreign technologies, for the construction of 200,000 tons per year ammonia synthesis plants, ammonia synthesis towers with single-layer forged thick-walled outer cylinders having a diameter of 2.4 meters and double-cone seals were designed and manufactured for the first time. The design software for such towers has not yet been fully mastered, nor is there any experience in designing and manufacturing ammonia synthesis towers with a capacity of 300,000 tons per year. 2.3 Other reaction equipment Reaction equipment is the key device used in chemical reaction processes. Their development trends vary; internationally, there is a shift from amplification based on experience to amplification through mathematical simulation, aiming for larger scale, higher efficiency, simpler structures, and automated operation, while research methods are moving toward a more integrated approach. Catalytic cracking reactors: The manufacturing technology in China has basically reached international advanced levels and is widely used in various refineries. Hydrogenation reactor: Well-known foreign manufacturers include Nippon Steel and Kobe Steel, among others. In China, a forge-welded hydrogenation reactor being developed for the coal chemical industry has an outer diameter of 5500 mm, a wall thickness of 340 mm, and a weight of 2040 tons; it is the heaviest hydrogenation reactor in the world. The reason for this gap lies in China’s weak innovation capabilities. Continuous reforming four-stack reactor: UOP’s patented technology enables this reactor to offer advantages such as high reaction efficiency, energy savings, reduced floor space, and lower investment costs. The design and manufacturing technologies for this have been mastered domestically, and the installation specifications for the internal components fully meet the requirements set by UOP’s technology. Polypropylene loop reactor: The renowned manufacturer is Hyment Company, and the design techniques and software for such reactors are becoming increasingly sophisticated. A 200,000-ton/year polypropylene loop reactor has been successfully developed in China and is now being put into use at Sinopec Shanghai. The structural design of loop tube reactors has been mastered, a mathematical model for combined stress calculation has been developed, and the technical challenges associated with the engineering scale-up of loop tube reactors have been resolved; the technical level is on par with that of foreign countries. Ultra-high pressure tubular reactors for high-pressure polyethylene plants: Companies in countries such as Japan, Germany, the United States, and the Netherlands possess this technology; in China, ultra-high pressure tubular reactors and coolers with capacities of 30,000 tons per year and 200,000 tons per year have been developed through digestion and absorption of foreign technologies. Compared to foreign countries, there is a significant gap in the development of process software and design technologies. In China, only the deep-hole drilling method is used, resulting in low material utilization efficiency. Furthermore, there are no dedicated standards or ordering technical specifications. 3. General mechanical equipment General chemical processing mechanical equipment mainly includes pumps used in the chemical industry, gas compressors, and valves, etc. 3.1 Chemical pumps Pumps are machines used for transporting liquids or increasing their pressure. Pumps are primarily used to transport liquids such as water, oil, acids, alkalis, emulsions, suspensions, and liquid metals; they can also convey mixtures of liquids and gases, as well as liquids containing suspended solids. Internationally, the major manufacturers of pumps for the petrochemical industry include Sulzer from Switzerland, KSB from Germany, and Goos from the United States. The production technology for pumps used in the petrochemical industry is quite mature, with a wide range of specifications and models, as well as a high degree of standardization. The main development trends are larger sizes, higher speeds, increased integration of mechanical and electronic components, and the development of complete pump systems. In particular, technology related to high-temperature pumps, low-temperature and ultra-low-temperature pumps, high-speed pumps, precision metering pumps, corrosion-resistant pumps, pumps for transporting viscous media and media containing solid particles, as well as shielded pumps, is developing rapidly. There are over 100 domestic manufacturers, which have developed manufacturing technologies and production equipment for more than 100 series and over 2,000 types of pump products, meeting the needs of the petrochemical industry. Compared with foreign countries, domestic pumps for the petrochemical industry are relatively backward in terms of design theory and methods; product development relies mostly on imitation and analogy, lacking theoretical foundations and experimental data ； The processing equipment and technological levels are relatively backward, resulting in low processing precision and low production efficiency ； The degree of product serialization and standardization is low, with a limited range of specifications and models ； Compared with foreign products, there is still a significant gap in aspects such as pump efficiency, quality and reliability, sealing performance, and corrosion resistance; therefore, many chemical process pumps are still imported. Rotary vane pumps: At present, the pass rate of domestically produced rotary vane pumps in China according to current standards is around 70%; when compared with international advanced levels, there is a greater gap in their overall performance. The main issues are severe oil leakage from the shaft seals; domestic shaft seals cannot withstand prolonged operation, and oil leakage is a fairly common problem ； It has high vibration and noise levels. Some products have poor dynamic balance, and some gears and bearings lack the necessary precision ； According to industry standards, the zero-flow compression ratio and maximum allowable pressure difference for some products do not meet the required standards; moreover, some enterprises have outdated production technology and equipment, which prevents them from ensuring the precision in the processing and assembly of components. Due to the aforementioned problems, the Roots pump operates unreliably with a high failure rate. Some pumps require maintenance after just a few months of operation, which is in sharp contrast to the Rotary pumps produced by German company L-H, which can operate for years without any need for maintenance. Vane pump: At present, the production of vane pumps in China has reached a mature level in terms of design, manufacturing, as well as performance and quality. The product quality manufactured by major companies is relatively stable, and the appearance quality has seen significant improvement. The long-standing problems of oil spraying and leakage have been brought under some control in recent years; the performance of the vane materials has improved, which has enhanced the reliability of vane pumps to a certain extent. The 2XZ-8A direct-connected vane pump produced by SDIC Nanguang Co., Ltd. is one of the few new models among vane pump products in recent years. It represents a technological advancement, ranging from conventional pumps to high-speed pumps, and it solves the problem of components aging and wearing out easily under conditions of high temperature and high speed operation. Vacuum pumps: At present, China has a complete range of vacuum pump products, with steadily improving quality, which basically meets the demands of the domestic market. After China’s accession to the WTO, competition in the international market has become increasingly fierce. However, there is still a significant gap in the quality of vacuum pump equipment produced in our country. It is urgent that we think carefully about this issue, explore appropriate solutions, and strive to reach international advanced levels as quickly as possible. Sliding vane pump: There is still a significant gap between domestic sliding vane pumps and foreign products. The main issues are: high noise and vibration. For pumps such as the H-150 slide vane pump, most domestic models require foot bolts; otherwise, severe pump drift occurs due to vibration ； Fuel spraying, oil leakage. Severe oil spraying when the pump starts, and oil leakage during operation; most products suffer from this issue ； Severe backflow of oil when the pump is stopped causes difficulties in starting, leading to motor overload ； It has poor stability and reliability; due to outdated manufacturing equipment, not only is the production efficiency low, but the interchangeability of components is also poor, which affects the stability and reliability of the products. High-pressure pumps: High-pressure pumps are exemplified by high-pressure methamine pumps and high-pressure liquid ammonia pumps. High-pressure methamine pumps and high-pressure liquid ammonia pumps are the types of pumps in urea plants that are subject to severe corrosion and present the greatest technical challenges. Reciprocating piston structures are commonly used in medium and small urea plants, while multi-stage centrifugal and high-speed partial-flow types are often employed in large urea plants. In recent years, reciprocating piston structure pumps have also emerged. Reciprocating pump units are large in size, complex in structure, and difficult to maintain; their pump bodies are prone to fatigue cracking, but they operate reliably and with high efficiency. High-speed partial-flow pumps use two-stage radial impellers, with rotational speeds of over 14,000 revolutions per minute. They have a compact design and operate smoothly, but issues related to sealing and wear are quite prominent and difficult to resolve. Multi-stage centrifugal pumps fall between the two; they are relatively easier to manufacture, have a better sealing structure, and are more reliable. High-pressure methylamine pumps of these three structural types have been developed in China, and there are no major issues regarding their manufacturing and operational reliability; however, at present these products are still mainly imported. Slurry pump: Taking the phosphoric acid slurry pump as an example. Phosphoric acid slurry pumps are a general term for various pumps used in the production of phosphate fertilizers; they represent a type of pump that is highly resistant to corrosion and wear. In the early stages of development of the phosphate fertilizer industry, the chemical corrosion-resistant pumps that were commonly used had a lifespan of only one week. As a result, experts in the pump industry both domestically and internationally conducted extensive research on aspects such as the structural design of phosphate slurry pumps, material testing, and seal technology. In the design of phosphate slurry pumps, the first issue to address is corrosion resistance, or the combination of corrosion and erosion wear. Therefore, special consideration should be given to the structural design as well as the fit between the pump casing and the impeller. The metal materials used for phosphate slurry pumps abroad are selected from different series depending on the properties of the medium. Domestic manufacturers and research institutions have also conducted studies on the corrosion resistance and wear resistance of various materials, developing their own series of materials such as ferritic stainless steels, duplex steels, and austenitic stainless steels. There are many specialized manufacturers of phosphate slurry pumps in China, and institutions such as the Chinese Academy of Sciences, universities, design institutes, and research centers are also involved in research and development. The issue of local production of phosphate slurry pumps has now been largely resolved. 3.2 Valves Valves are devices used to control the flow rate, pressure, and direction of fluids. They are classified into the following 7 categories according to their purpose: Valves for oil refining plants. The valves required in refining plants are mostly pipeline valves, including gate valves, globe valves, check valves, safety valves, ball valves, butterfly valves, and steam traps. Among these, gate valves account for about 80% of the total number of valves (valves represent 3% to 5% of the total investment in such plants). Valves for fiber optic equipment. Textile fiber products mainly fall into three categories: polyester, acrylic, and vinylon. The valves required are ball valves and jacketed valves (jacketed ball valves, jacketed gate valves, jacketed globe valves). Valves for acrylonitrile plants. This type of equipment generally requires valves manufactured in accordance with API standards, mainly gate valves, globe valves, check valves, ball valves, steam traps, needle valves, and plug valves; among these, gate valves account for about 75% of the total number of valves. Valves for ammonia synthesis plants. Due to the differences in ammonia synthesis raw materials and purification methods, the process flows vary, and thus the technical requirements for the valves also differ. Currently, domestic ammonia synthesis plants mainly require gate valves, globe valves, check valves, steam traps, butterfly valves, ball valves, diaphragm valves, control valves, needle valves, safety valves, as well as high- and low-temperature valves. Among them, stop valves account for 53.4% of the total number of valves used in these plants, gate valves make up 25.1%, steam traps account for 7.7%, safety valves represent 2.4%, while control valves, cryogenic valves, and others account for 11.4%. Valves used in ethylene plants. The ethylene plant is a key facility in the petrochemical industry, and it requires a wide variety of valves. Gate valves, globe valves, check valves, and lift-rod ball valves account for the majority, among which gate valves come first. “Under the 15th Five-Year Plan, the country still needs to build 6 ethylene plants with an annual production capacity of 660,000 tons each, which will result in a significant demand for valves. In addition, large-scale ethylene and high-pressure polyethylene plants also require ultra-high-temperature, low-temperature, and ultra-high-pressure valve series. Valves for air separation units. “\"Air separation\" refers to the process of separating air; such systems primarily require stop valves, safety valves, check valves, control valves, ball valves, butterfly valves, and low-temperature valves. Valves for polypropylene plants. Polypropylene is a polymer compound typically produced by polymerizing propylene, and this type of equipment mainly requires gate valves, globe valves, check valves, needle valves, ball valves, and steam traps. 3.3 Fittings Pipelines/fittings are devices made up of pipes, pipe connectors, valves, etc., used for transporting gases, liquids, or fluids containing solid particles. In the coming period, the focus for pipe fittings will be on tackling key challenges, promoting the application of, and advancing the research and development of 43 pipeline technologies. Through the implementation of these key technological projects, five major series of pipeline technologies will be gradually established: oil and gas transportation technologies, oil and gas storage technologies, pipeline engineering technologies, pipeline integrity assessment and related technologies, as well as operation management and information technologies for oil and gas pipelines, thereby comprehensively improving the level of pipeline technology. These 43 technologies include 26 bottleneck technologies that require focused efforts to overcome, 10 new technologies to be promoted and applied, and 7 reserve technologies for advanced research. 3.4 Industrial Furnaces Industrial furnaces are thermal processing equipment used in industrial production to heat materials or workpieces by utilizing the heat generated from fuel combustion or electrical energy conversion. Based on their different uses in chemical production, they can be classified as heating furnaces, cracking furnaces, conversion furnaces, etc. Ethylene cracking furnaces: Companies that possess this technology include ABB, KBR, S&W, KTI, and Linde, among others. The process technology is evolving toward higher temperatures, shorter residence times, and lower hydrocarbon partial pressures in order to further improve selectivity and reduce costs. Overall, China’s pyrolysis technology still lags significantly behind the world standard, as evidenced by small-scale facilities, high raw material consumption, energy consumption, and production costs, short operation cycles, low control levels, repeated introduction of foreign technologies, and slow progress in development and innovation. Converting furnaces and vaporization furnaces: The main companies abroad that have developed large-scale industrial installations include Kellogg Company in the United States, Imperial Chemical Industries in the United Kingdom, and Topsoe in Denmark, among others. The converter furnaces in domestic-designed and manufactured synthetic ammonia plants with an annual capacity of 200,000 tons, which use natural gas as a feedstock, feature high-temperature furnace tubes and high-frequency welded finned tubes in the convection section that were developed in China for the first time. However, to date, there is no set of domestically produced converter furnaces with an annual capacity of 300,000 tons available for use in industrial plants. Vaporization furnaces cannot yet be designed domestically in China, and most coal-water slurry nozzles rely on imports. Waste heat boiler: It is an important energy-saving device, commonly used in ethylene cracking and ammonia synthesis plants. German company Borsig and American company Kellogg possess relatively advanced technologies in this area. In China, focused efforts have been made on the comprehensive technology development of floating-head waste heat boilers; at the same time, experimental research on key technologies for other types of conversion gas boilers has also been carried out. Large-scale programs such as overall design, stress finite element calculation and analysis for thin tube sheets, and numerical calculation and analysis of internal circulation in fire-tube waste heat boilers have been developed. The first floating-head waste heat boiler developed was used in the 200,000-ton/year ammonia synthesis plant at Sichuan Chemical Industry Complex, but no waste heat boiler for 300,000-ton/year conversion gas production has yet been manufactured. 3.5 Compressors Gas compressors: These are key devices for generating pressure energy and transporting gases. There are turbine compressors and reciprocating compressors, with Japan, the United States, Germany, Italy, Switzerland, and other countries possessing relatively advanced design and manufacturing technologies in this field. Over the years, through domestic independent development or by overcoming various challenges after introduction, significant breakthroughs have been achieved. Among them, the horizontal split centrifugal compressors and axial flow compressors are close to the advanced level of similar international products. Centrifugal compressors: The international trend is toward larger capacities, with the development of compressor products that are high-pressure, low-flow, low-noise, and highly efficient. There are over a dozen domestic manufacturers, particularly the Shenyang Blower Factory, Shanghai Blower Factory, Shaanxi Blower Factory, and others. Domestic centrifugal compressors with high technology, high parameters, high quality, and special features still cannot meet the demands; about 50% of them still have to be imported from abroad. Furthermore, there is still a gap compared to foreign countries in terms of technical level, quality, and completeness, and no mature experience exists in the design and manufacture of large gas compressors. Reciprocating compressors: They typically feature a skid-mounted, foundation-free design with a fully enclosed structure to reduce noise, **thereby saving costs related to installation, foundations, and commissioning. There are over 20 domestic manufacturers, which have developed dozens of compressor series such as L, D, DZ, H, and M, resulting in hundreds of different products; however, large reciprocating compressors still cannot meet the demands. 4. Instruments and Meters Instruments and meters are devices or equipment used to detect, measure, observe, and calculate various physical quantities, material compositions, and physical property parameters. In a broader sense, instruments can also have functions such as automatic control, alarm signaling, signal transmission, and data processing. Industrial automation instruments: Focus on the development of master control system devices based on fieldbus technology, as well as intelligent instruments and special-purpose automation instruments ； Comprehensively expand the scope of services, advance the digitalization, intelligence, and networking of instrumentation systems, and complete the transition of automated instruments from analog technology to digital technology, so that digital instruments account for over 60% within 5 years ； Accelerate the commercialization of automated software with independent intellectual property rights. Environmental protection instruments and equipment: Focus should be placed on the development of automated control systems for monitoring the atmospheric and aquatic environments. Given the need to strengthen environmental enforcement, accelerate environmental protection efforts, increase investment in such initiatives, and foster the environmental protection industry as a new driver of economic growth, and considering China’s more than 5,000 environmental monitoring stations sowie the large-scale demand for urban wastewater treatment and industrial wastewater treatment, the market for environmental protection instruments and equipment is set to experience significant growth in the future. According to incomplete statistics from relevant authorities, the output value of environmental protection instruments, meters, and monitoring systems in China was approximately 1.17 billion yuan in 1998; by 2005 this figure had risen to 4.2 billion yuan, reaching the international advanced level of the late 1990s, with a domestic market share of 50%–60%. By 2010, this figure was expected to reach 11 billion yuan, and the domestic market share would exceed 70%. It is evident, therefore, that its market prospects are very broad. Analytical chemistry instruments: Key research areas include: first, high-throughput analysis, which enables the testing of a large number of samples per unit of time ； The second is extreme condition analysis, among which single-molecule and single-cell analysis and manipulation are currently popular research topics ； Third is online, real-time, on-site, or in-situ analysis, which enables rapid or end-to-end analysis from sample collection to data output ； Fourth is the combined technology, which involves integrating two (or more) analytical techniques to complement each other and thereby carry out more complex analysis tasks. The combinations of coupling technologies and coupling instruments, particularly the emergence of triple and even quadruple systems, have become an important direction in the development of modern analytical instruments ； Fifth is array technology; if coupled analysis techniques are viewed as serial methods in computers, then array technology is equivalent to parallel computing methods in computers. Like computers, the array method is the best approach for significantly increasing analysis speed or the batch processing capacity of samples. Once the concept of parallel arrays is seamlessly integrated with integration and chip manufacturing technologies, analytical chemistry will advance into new fields. A Review and Outlook for the Petrochemical Equipment Manufacturing Industry: 2006 was the starting year of the 11th Five-Year Plan, as well as the first year in which China’s strategy to revitalize its equipment manufacturing industry was implemented; it held a pivotal significance as a bridge between the past and the future. According to Cai Weici, vice president of the Machinery Industry Federation, the economic performance of the entire industry in 2006 was favorable, showing six key characteristics: first, the operational speed of the industry rebounded significantly, returning to a high level once again ； Second, the overall operational quality is good, and economic benefits are growing faster than production and sales volumes ； Third, key industries are growing at a rapid pace, and the trend in changes within the industry structure is encouraging ； Fourth, the industrial structure continues to improve, with ongoing progress in technological advancement ； Fifth, exports grew faster than imports, leading to a rapid reduction in the trade deficit ； Sixth, investment growth is showing a downward trend at high levels, while capacity expansion remains strong. In terms of the oil and chemical equipment manufacturing industry, building on the positive trends of previous years, the industry’s performance in 2006 – indicators such as industrial added value, sales revenue, profits, and exports – all maintained a high growth rate of over 40%. At the same time, the industry has also made significant progress in areas such as independent innovation, localization, upgrading of product structures, and the development of industrial clusters. The three key types of major petroleum and chemical equipment identified by the central government for focused development all achieved encouraging results in 2006: among them were offshore oil and gas engineering equipment such as 9,000-meter oil rigs, 300,000-ton floating production storage and offloading vessels, and 300,000-ton supertankers ； For the million-ton ethylene plant, there are 640,000 tons per year of ethylene cracking gas compressors, 300,000 tons per year of polypropylene loop reactors, and 720,000 tons per year of ethylene cryogenic tanks; the complete set of process software for the million-ton PTA plant has been successfully developed ； Coal chemical equipment includes the widespread use of 60,000 cubic meter air separation units, coal liquefaction reactors with a capacity of 2,000 tons, as well as gas generation furnaces powered by various advanced technologies. Problems exist. According to Cai Weici, while the machinery industry is developing at a rapid pace, it also faces various concerns: the key players in its development are weak and unstable ； The shift in the mode of growth is not fast enough ； The ability for independent innovation cannot meet the needs of structural upgrading ； Bottleneck constraints in the supply of key raw materials are becoming increasingly prominent. In short, the industry’s ability to withstand risks for sustained development remains quite fragile. In the industry of oil and chemical equipment manufacturing, the level of intelligence and quality of oil drilling rigs in China still needs to be improved. The variety of drilling rigs is relatively limited, and there is a lack of the capability to design and produce specialized drilling rigs ； The overall technical level of geophysical exploration and logging equipment is significantly behind that of foreign products, resulting in no competitive advantage in the international market ； In terms of petrochemical equipment, there is a lack of a spirit of continuous innovation; generally, there is an excess capacity in the manufacturing of equipment specific to the petrochemical industry, while there is a shortage in the manufacturing capacity for large-scale equipment. Overall in the industry, companies generally have weak R&D capabilities, low technical levels, and a lack of core technologies and key products with independent intellectual property rights; their innovation capabilities are not strong ； Research resources are scattered and disconnected, lacking overall planning ； There are a large number of small enterprises, each operating independently; there is severe low-level duplication of investments, which leads to wasted production capacity and a certain degree of disorderly competition among peers. In terms of imports and exports, according to Zheng Guowei, head of the Import Office at the former Ministry of Machinery Industry, although China’s exports of petrochemical machinery products grew rapidly in 2006, with the trade surplus increasing steadily, the situation was favorable. However, it should be noted that the current structure of imports and exports of such machinery products in China is not entirely ideal; the proportion of exports of products with domestic brands and high-tech products is low, as is the proportion of imported key components for major equipment as well as innovations in related technologies. To this end, the industry must not only continuously update its industrial equipment to meet current production needs, but also take a long-term perspective and make a determined effort to strengthen research and development methods, capabilities, and infrastructure. It is necessary not only to focus on bringing in technology and talent, but also to make a determined effort to develop one’s own core technologies, R&D personnel, and high-skilled professionals. Only in this way can our development be based on sustainable principles, and only then can we have a certain degree of autonomy in facing risks in today’s international competition. Outlook for 2007 Considering the impact of the continuous decline in oil prices since August 2006, so far the drop in oil prices has not had a significant effect on the oil drilling and production equipment industry; various key economic indicators continue to show rapid growth, and the number of enterprises as well as total investment levels remain on the rise. The manufacturing industry for oil refining and chemical equipment is relatively sensitive; since September 2006, there have been two consecutive months of an increase in the number of companies suffering losses as well as in the total amount of those losses, with a significant slowdown in the growth of key economic indicators. In 2007, the growth rate of the oil drilling and production equipment industry is expected to remain at this year’s level, with increases in total industrial output and product sales revenue exceeding 65% ； The growth in the refinery and petrochemical equipment industry is slowing down, with increases in total industrial output and product sales revenue ranging between 25% and 30% ； The increase in pressure vessels is relatively small, around 20%. In 2007, the industry-wide growth rate is expected to be around 38%–40%.
