Lifting of the settler in the catalytic cracking unit of the Sinopec Refining project begins 2019-05-28 Source: Print Article Petrochemical News On May 27, lifting and installation of the first section of the settler began – one of the key equipment components in the 10 million tons per year oil refining facility and the 4.2 million tons per year catalytic cracking unit as part of the Sinopec Refining integrated project. “The construction of the two core equipment units – the regenerator and the settler – presents two major challenges. First, the technical requirements for the large-scale concrete foundations are very high, making it extremely difficult to organize the construction and ensure proper safety management. The foundation slab beneath this framework is 3.95 meters deep, while the foundation above ground is 50.5 meters high; it represents the highest concrete foundation for equipment frameworks in this COSIC project. During construction, the contractor, Sinopec Luoyang Engineering Company, carried out meticulous organization and coordination, as well as careful planning to achieve high quality standards ； Strict quality control ； Nanjing Yangzi Petrochemical Engineering Supervision carries out thorough inspections and strict quality control ； The civil engineering construction team strived for excellence, ensuring that the framework foundations for the “two units” were completed on schedule and to high standards. The framework foundations for the sedimentators, which featured excellent quality both in terms of appearance and structure, were recognized by the Quality Management Department of the Sino-foreign joint venture’s Guangdong Petrochemical Integration Project Management Department as a “model project for the entire plant”. Secondly, the “two types of equipment” have large diameters and high quality requirements; there are many different types of internal components, and lining work is also necessary. Assembly and welding are carried out on-site, and the modular assembly process is complex. Additionally, due to the compact design of these devices, the space available for prefabrication and assembly is limited, making the production of these devices and their modular installation extremely difficult. Shi Jian Company, which is responsible for the installation, attached great importance to this task. It brought together experts with extensive experience in the construction and management of catalytic cracking units as well as technical engineers to prepare a construction plan for the “two units.” Special meetings were held with the contractor, supervisors, and other parties involved in the construction process to discuss these plans in detail, with the aim of developing and optimizing a modular assembly method for the ground-based components of these “two units.” The approach adopted was to pre-assemble and weld the cylinder sections on the ground in 9 separate segments; thereafter, the internal components of the “two units” as well as the steel structure platforms were all assembled modularly at a lower height on the ground, before being lifted and installed segment by segment. Through the five months of hard work by the workers from Shijian Company, the assembly and welding of sections 9 through 10 of the \"two units\"’ cylindrical structures were completed by mid-May; the first section of the regenerator was hoisted into place on May 19. The settler has a total height of 66.32 meters, with a maximum diameter of 9 meters and a minimum diameter of 1.9 meters; it has a conical shape with a larger upper part and a smaller lower part, and its total weight is 994 tons. On the afternoon of May 26, the first section of the sinker, which is 21.8 meters high, 1.9 meters in diameter and weighs 20 tons, was lifted to a height of about 80 meters using a large crane. The lower end of the sinker was then aligned with the center of the 50.5-meter-high frame foundation, and it was slowly lowered to a temporary support at a height of 1.9 meters above the ground. Thus, the important installation milestones for the “two units” of the catalytic cracking unit in the Zhongke project, which began in late May, have been achieved on schedule. (Gao Mingliang)

The sedimentator framework of the Sinopec refining project was recognized as a \"model project for the entire plant\". April 19, 2019 – Source: Sinopec News Network. Print article. Petrochemical news: The concrete foundation of the reaction sedimentator equipment in Sinopec’s 10 million tons per year refining project and 4.2 million tons per year catalytic cracking unit, now that all internal and external scaffolding as well as formwork have been removed, makes this large-scale structure stand out like a magnificent and exquisite \"artwork\" on the land of western Guangdong. During the construction of this framework, the contractor responsible for the project, Sinopec Luoyang Engineering Company, Nanjing Yangzi Petrochemical Engineering Supervision, and Shandong Jinding Construction and Installation Company, all worked diligently to achieve excellence. They exercised strict control over technical aspects, ensured high quality standards, and strived for perfection in the construction process. The concept of using \"model projects as a guide\" was applied to every stage of framework construction; high-quality models were used to standardize construction operations, and uniform systems and standards were implemented. As a result, the framework that was built met high standards in terms of both appearance and quality. It was recognized by the Quality Management Department of Zhongke (Joint Venture) Guangdong Refining and Chemical Integration Project Management Department as a \"model project for the entire plant.\" On April 17th, honorary medals and certificates for being the \"Model Concrete Framework Project for the Entire Plant\" were awarded to the construction team, the general contractor, and the supervision team involved in the project. The framework consists of two parts: an underground cap foundation and an above-ground frame foundation. The underground cap is 44 meters long, 24.4 meters wide, and 2.5 meters thick, with a foundation depth of 3.95 meters ； The reinforced concrete frame on the ground is 12 meters long, 12 meters wide, and 50.5 meters high; it represents the tallest concrete structure foundation for the Sinopec refining project. A total of 680 tons of rebar were used in its construction, and 5,423 cubic meters of concrete were poured. The load-bearing scaffolding of the \"Man Tang Hong\" type as well as the floor-standing working scaffolds required 528 tons of steel frames. This structure has high technical and quality requirements, making construction organization and safety management extremely challenging. All participating units regard this as a top priority in civil engineering construction; they prepare thorough construction organization plans, develop detailed technical construction plans, and organize the construction in strict accordance with established procedures. It is essential to turn the concrete frame of the settlement device into a model project first. Therefore, great efforts were made to achieve \"strictness, precision, and practicality\": first, strict control was exercised over material inspection – strength tests were carefully conducted on the steel bars that arrived, as well as on the ready-mixed concrete supplied. II. Strictly control the inspection processes during steel component construction; aspects such as the spacing between rebars, the proper offset between the joints of adjacent rebars, and the installation height of embedded shims in relation to the curvature of the foundation surface are all carried out in accordance with the requirements specified in the project plans. III. Strictly control the concrete pouring process: conduct slump tests on the concrete before each pour, and use methods such as layered and continuous pouring during the pouring stage. IV. Pay close attention to external lighting; strictly control the equal spacing when installing the \"Man Tang Hong\" scaffolding in accordance with the plan, ensure the density of the timber used for formwork support, properly adjust the vertical and horizontal alignment of the formwork, and tighten the nuts on each bolt used to fix the formwork against the walls. V. Great care is taken in the detailed work; all wooden formwork is of high quality, and a sealant is applied to it before use. After the formwork is properly set in place, the gaps around the bolts used to connect the formwork together, as well as the gaps between the formwork pieces, are sealed using sealing strips or duct tape. VI. Ensure that the concrete is vibrated evenly and compactly. Implement a responsibility system for the workers responsible for vibrating the concrete, so as to avoid under-vibration, insufficient vibration, or over-vibration, and to ensure that no construction joints are formed after concrete pouring, nor are there any issues such as honeycombing or pitting. Through the above measures, it was ensured that the concrete pouring did not result in leakage or seepage, and that the frame, once the formwork was removed, had a smooth, even surface that was beautiful and impressive. During the framework construction process, from measurement, positioning, and setting out to the completion of the framework foundation and handover for safety checks, there are more than a dozen different steps involved. Each of the participating units treats each of these steps as a quality control point. Before starting work on any step, technical and quality officers provide thorough and detailed safety instructions to the workers. Before a step is completed, an inspection team composed of engineers from various participating units in charge of engineering, technology, quality, and safety conducts inspections, verifies the work, and signs off on it. Thanks to the high level of attention paid by all parties involved and the effective management measures implemented, along with the commitment of all workers to deliver top-quality work, the construction of the sinker framework was carried out to an excellent standard, making it a \"model project for the entire plant\" within the Zhongke Refining and Chemical project.

The third section of the catalytic cracking settler in the Shijian Zhongke project was successfully lifted into place. June 18, 2019 – Source: Sinopec News Network. Print article. Petrochemical news: On June 16, after several days of rainy weather, the Zhongke Refining and Chemicals project site finally saw clear skies. Taking advantage of this favorable condition, the refining division of Shijian Company quickly mobilized its staff. At 17:10 in the afternoon, with the help of a 650-ton crawler crane, the third section of the 4.2 million tons per year catalytic cracking unit in the Zhongke Refining and Chemicals integrated project was successfully lifted and installed. The regenerator and settler are the core equipment of the entire catalytic cracking unit; Shijian Company, which is responsible for their installation, attached great importance to this task and, after careful planning, decided to lift them in five stages. What was lifted this time is the third section of the settler, which consists of a transition section, a skirt, and the settler’s cylinder, and weighs approximately 50 tons. To ensure the smooth installation of the settler, Shijian Company developed a detailed construction plan. Several coordination meetings were held to thoroughly discuss and negotiate various aspects of the construction work with the installation team, technical experts, manufacturers, and others ； After five months and several revisions, the optimal construction plan was finalized. By using ground-based modular assembly followed by segmented modular lifting, **the workload and difficulty of installation at heights are reduced, which not only lowers safety risks and costs but also improves construction quality and efficiency. Entering May, rainfall in Zhanjiang increased gradually, posing significant challenges to the progress of on-site construction. The 10th Construction Company overcame these difficulties, took proactive measures, and organized its work efficiently; within less than a month it completed the installation and lifting of the three settlement device units, thereby ensuring that the installation of these devices proceeded according to the planned schedule.

At 20:00 on February 28th, with the pouring of the last batch of concrete completed, the highest concrete structure in Sinochem Refining and Chemicals’ 4.2 million tons per year catalytic cracking unit – the 50.45m reactor settler frame – was successfully topped out. To date, the main structural frameworks of the two core units in Sinochem Refining’s 4.2 million tons per year catalytic cracking unit – namely the regenerator and the settler – have all been constructed.

The 4.2 million tons per year catalytic cracking unit was under the general contract of Luoyang Engineering Company; Shandong Jinding Construction and Installation Engineering Co., Ltd. was responsible for the civil engineering work, while Shijian Company handled the installation tasks. Through systematic organization and coordination by all involved parties, as well as the extra efforts put in by the construction teams, it was possible to complete the pouring of the framework on schedule. The framework of the reactive settler consists of an underground foundation and an above-ground frame. The underground foundation is 3.95 meters deep, 44 meters long, 24.4 meters wide, and 2.5 meters thick; a total of 2,500 cubic meters of reinforced concrete was used for its construction. The reinforced concrete frame on the ground is 12 meters long, 12 meters wide, and 50.45 meters high; it has six floors and represents the tallest concrete frame structure in the Sinopec Refining project. For the main structure, a \"full-house\" load-bearing scaffold was used; 528 tons of scaffold bars were employed in total, 680 tons were used for the fabrication and installation of rebar, and 2,923 cubic meters of concrete were poured. The civil engineering contractor, Shandong Jinding Building Installation Engineering Co., Ltd., has given top priority to the construction of the reactor settler frame in the catalytic cracking unit. Kong Dongming, the chief engineer in charge of the construction of this project, carefully organized the preparation of the construction technical plans. Before the framework construction began, five experts reviewed the \"Special Construction Plan for Scaffolding,\" the \"Special Construction Plan for High-Height Formwork and High-Bearing Formwork Systems,\" and the \"Special Plan for Formwork Support at the 39.8-meter Floor Transition Layer,\" thereby providing a solid guarantee for the safe and high-quality completion of the high-rise framework. Construction above the ground level of the reactor settler frame began in November 2018. During the 4-month frame construction period, the owner, general contractor, supervisor, and all construction parties strictly monitored the quality control at each stage of the work ； All construction workers worked hard and with determination; steelworkers, carpenters, concrete workers, and other tradespeople collaborated closely, upholding the collectivist spirit of putting the greater good first. They worked overtime to complete the construction tasks on schedule, thus fulfilling in practice the solemn commitments made in the owner’s milestone responsibility document. The successful completion of the framework for the reaction settler creates favorable conditions for the subsequent lifting and installation of the core equipment of this facility, namely the two types of reactors.

“The two units are generally assembled on-site; it is quite rare to see them supplied and lifted as a complete unit, like at the refineries in Nigeria.

It mainly relates to material processing, site facilities, construction timeline, and other requirements. It can also be referenced domestically; for example, conversion furnaces used to be assembled on-site as well

On August 7, Sinopec’s Zhongke Project held a mobilization meeting for the \"150-Day Intensive Work\" campaign, aiming to fully implement the guidelines set forth by Chairman Dai Houliang regarding the construction of the Zhongke Project.
