Sinopec News Network reported that on the afternoon of August 31, the fractionation tower (C-3102) of Shijian Maoming High-end Carbon Project was successfully and smoothly hoisted into place through the close cooperation and scientific construction of all participating personnel. It is understood that the fractionation tower is 49.39 meters long, has a maximum diameter of 2.6 meters, and weighs 107.1 tons. Previously, after the equipment arrived, it was the rainy season in Maoming, which was also affected by typhoons. The project department scientifically arranged a series of construction processes to improve rainproof, moistureproof, windproof, and heatstroke prevention measures during the operation in advance. ； Close contact with the owner and the supervisory unit, close connection with the construction process, proactive shift work at night, and regaining time delayed due to weather. Preparatory work such as attached ladder platform, attached tower pipeline, insulation, etc. are in place step by step according to procedures. ； The persons in charge of various professions strictly controlled the construction quality of welding, anti-corrosion, prefabrication, insulation and other construction, and withstood the test of hot summer weather and rainy weather to ensure that the fractionation tower was ready for hoisting. This construction adopts the single-host crane delivery method, using a 400-ton crawler crane as the main crane and a 300-ton truck crane as a tail-sliding crane. Because the site space is narrow and there are many steel structures around it, the position and angle movement of the lifting equipment before hoisting were carefully considered and carefully calculated, and the safety technology briefing was fully covered. During this period, two cranes first lifted the equipment, the main crane was responsible for lifting the equipment, and the tail crane was responsible for delivering it, gradually transitioning the equipment from a horizontal state to a vertical state. After the equipment reached an upright state, the tail crane unhooked, the main crane rotated, and the equipment was installed on the foundation. After alignment, the anchor bolts were tightened to complete the hoisting work. At present, a total of 55 pieces of equipment have been installed in high-end carbon projects, and on-site construction is proceeding in an orderly manner.

Nowadays, the names of the projects are relatively high-profile, and you can’t tell what the products are.
There seems to be a difference. At 8:38 a.m. on November 1, 2019, the pile driver at the construction site of the 100,000 tons/year high-end carbon material project of Sinopec Shijian Maoming Engineering Project Department successfully started drilling. The sound of "cracking" firecrackers resounded in all directions, playing the prelude of struggle. It was a lively scene and kicked off the next step of pile foundation construction. The total land area of the high-end carbon project is about 97,300 square meters. The construction content includes a vacuum distillation unit with a processing scale of 500,000 tons/year, a hydrodesulfurization unit of 300,000 tons/year, a needle coke unit of 300,000 tons (raw material)/year, and a needle coke calcining unit of 100,000 tons (cooked coke)/year. The concrete volume of China Civil Engineering Construction reaches 43,000m³, the steel structure is 6,000 tons, and the process pipeline is 35,593.8 meters. It also builds necessary public works and auxiliary facilities. The project department organized the construction of this project based on the concepts of factoryization, modularization, soilless, specialization, and informationization.
Main research and development, ten years of hard work Shanghai Petrochemical is one of the largest refining and chemical integrated enterprises in China, and was also the largest acrylic fiber manufacturer in China. Relying on the advantages of the acrylic fiber industry, the company took the lead in carrying out communication research and technical research on carbon fiber as early as the 1980s. In 2007, Sinopec decided to deploy the research and development and industrialization of PAN-based carbon fiber, and implemented the construction project in Shanghai Petrochemical. With the strong support of Sinopec and Shanghai Municipality, Shanghai Petrochemical, together with dozens of scientific research institutes, universities, enterprises, etc. such as Shanghai Petrochemical Research Institute, Shanghai Engineering Company, Fudan University, etc., has developed a collaborative innovation that combines "production, academia, research, and application" with enterprises as the main body. A new path, and relying on the strong basic theoretical research of universities and the seamless connection of engineering technology development of enterprises, without "moving forward in the dark", without "meaningless imitation", without "blind trial and error", under the guidance of clear goals, taking less detours, crossing the gap, and achieving the accumulation of technology. With the concerted efforts of all teams, carbon fiber research is advancing rapidly: In November 2008, the pilot plant was built ； In March 2009, 12K raw silk was successfully developed. In September 2012, using the self-developed domestically unique NaSCN (sodium thiocyanate) wet process and a complete set of technologies with independent intellectual property rights, the first phase of Shanghai Petrochemical's annual production of 3,000 tons of raw silk and 1,500 tons of carbon fiber project was completed and put into operation, forming an annual industrial production capacity of 3,000 tons of polymer, 1,500 tons of raw silk, and 500 tons of carbon fiber. In May 2016, Shanghai Petrochemical carried out industrial research and testing of carbon fiber 48K large tow raw filaments. In January 2018, the company successfully developed the polymerization, spinning, and oxidation carbonization process technologies for large-tow carbon fiber, forming the technical basis for a kiloton-level PAN-based 48K large-tow carbon fiber complete technology package. In March, the company successfully trial-produced domestically produced 48K large-tow carbon fiber and implemented the entire process. According to tests, after the 48K large-tow raw filaments are oxidized and carbonized into 48K carbon fiber large-tows, the single-filament strength reaches high performance. This laid a solid foundation for the technical upgrade of general-grade carbon fiber (small tow + large tow) in the previous stage and the production of high-performance carbon fiber. It is understood that since the start-up of the first-stage kiloton carbon fiber device, as of May 2018, the device has produced a total of 4,286 tons of raw silk and 709 tons of carbon fiber. The unique NaSCN wet strand process enables the produced carbon fiber to have excellent surface structure and interface properties, which can greatly enhance the performance of carbon fiber composite materials.
Needle coke is a high-quality carbon material. It is named after the particles are crushed into fine needles. Needle coke has a metallic luster in appearance, a layered structure inside, good orientation, and good electrical and thermal conductivity. Therefore, it is the main raw material for manufacturing ultra-high-power electrodes for steelmaking. According to different raw materials, needle coke production is divided into oil-based needle coke and coal-based needle coke. The needle coke produced from petroleum heavy oil as raw material is oil-based needle coke; the needle coke produced from coal tar pitch and its fractions as raw material is coal-based needle coke. Compared with coal-based needle coke, oil-based needle coke has higher volume density and mechanical strength, better adsorption of binders, and easier control of the graphitization process. However, because my country is rich in coal and short of oil, coal-based needle coke has certain raw material advantages in my country. The coal-based needle coke process is mainly divided into three steps. One is raw material pretreatment, the second is delayed coking process, and finally the needle coke is obtained through calcination. With the continuous development of technology, needle coke production technology has achieved breakthrough development after a long period of exploration and research. At this stage, domestic needle coke can not only produce higher-power electrode products, but also can, to a certain extent, replace imported needle coke in the production of ultra-high-power electrode products, with a wide range of applications.
With the rapid development of my country's steel industry and the rapid growth of converter rod production, my country's electric furnace steel production has increased year by year, which has resulted in a large demand for needle coke. After 2017, * * Environmental protection has also promoted the development of electric furnace steelmaking. It is expected that the demand for needle coke will exceed 600,000 tons/year by 2020, and the demand for lithium batteries may exceed 500,000 tons/year. Driven by demand and profits, the full release of production capacity by the end of 2019 will generate 550,000 tons of new production capacity, which will demand approximately 1.5 million tons of coal tar. Most of these production capacities are concentrated in Shanxi, which makes coal tar, which is already in tight supply in the region, even more scarce. The profit situation is higher than that of deep-processed products such as coal pitch. With auctions guiding market prices, it has had a considerable impact on pushing up the coal tar market. The application market of coal-based needle coke in the next few years will mainly be in ultra-high-power graphite electrodes and lithium battery anode materials. Although steel companies have stopped falling and rebounded through capacity reduction, the development prospects are still not optimistic. The lithium battery industry has entered a period of rapid development, and the rapid development of new energy vehicles has also driven the demand for needle coke. Therefore, the price of the coal tar market has grown rapidly under the leadership of a new technology and the huge profits of needle coke. Although the downstream operation of coal tar such as coal tar carbon black is difficult to support the high price of coal tar, needle coke companies are more enthusiastic about purchasing coal tar. Therefore, when this new industry suppresses the old industry, companies need to increase their market competitiveness by improving their technical level and gaining insight into the development of market demand.
