The refining and chemical transformation and upgrading project of Jilin Petrochemical Company with an annual output of 120 tons of ethylene unit. The refining and chemical transformation and upgrading project of PetroChina Jilin Petrochemical Company is the project of Jilin Provincial Committee and Provincial Committee.* * and China National Petroleum Corporation to thoroughly implement the Party’s * It is the largest single industrial project invested in Jilin Province since the founding of the People's Republic of China and the first chemical project of PetroChina to use all green electricity. It is an important measure for the high-quality development of PetroChina's refining and chemical business and the strategic optimization and adjustment of the refining and chemical business layout in Northeast China. It is important for promoting the revitalization, development and maintenance of Jilin. * * Important industrial chain supply chain security, promote * * The implementation of the strategy to revitalize the old industrial bases in Northeast China is of great significance for striving to promote the high-quality development of PetroChina and the construction of an ever-lasting world-class comprehensive international energy company. As the most critical device of the transformation and upgrading project, the 1.2 million tons/year ethylene plant covers a total area of ​​118,600 square meters. It adopts the ethylene technology of Sinopec Engineering & Construction Co., Ltd. and can produce 1.2 million tons of polymer grade ethylene and 587,000 tons of polymer grade propylene annually. It also produces by-products such as hydrogen, mixed C4, crude cracked gasoline, cracked diesel and cracked fuel oil. After the new ethylene and downstream units are put into operation, the total ethylene production capacity of Jilin Petrochemical will reach 1.9 million tons/year, and the ethylene production capacity and chemical scale will reach the domestic advanced level. The "reducing oil and increasing chemical" has achieved remarkable results, and an industrial layout and product structure with Jilin Petrochemical's characteristics and competitive advantages will be formed. 3 months! All 14 modules of 7 cracking furnaces are hoisted in place! The 1.2 million tons/year ethylene unit cracking furnace of Jilin Petrochemical Company's refining and chemical transformation and upgrading project has a total of 7 cracking furnaces. Furnace body wall panels, etc. are made on-site and installed in accordance with the overall hoisting and installation method of 14 modules. The cracking furnace project began to be installed in September, with the first crane up to 14 cranes, which lasted nearly three months. The next step will be the installation transition period. In September 2023, at the construction site of the 1.2 million tons/year ethylene unit, the core device of Jilin Petrochemical's refining and chemical transformation and upgrading project, the furnace plates in the radiant section of the cracking furnace are being assembled intensively. After the furnace plates are assembled in accordance with the installation sequence, the cracking furnaces will be installed one by one as planned. At 14:27 on December 2, 2023, the cracking furnace construction area of ​​the 120-ton-per-year ethylene unit area of ​​Jilin Petrochemical's refining and chemical transformation and upgrading project, which is 29.24 meters long, 4.55 meters wide, and weighs 120 tons, the No. 2 cracking furnace Section B furnace hoisting operation was successfully completed. At 14:27 on December 2, the cracking furnace construction area of ​​the 120-ton-per-year ethylene unit area of ​​Jilin Petrochemical's refining and chemical transformation and upgrading project, which is 29.24 meters long, 4.55 meters wide, and weighs 120 tons, the No. 2 cracking furnace section B furnace hoisting operation was successfully completed. For this hoisting, one 400-ton crawler crane is responsible for the main crane, and two 150-ton crawler cranes are responsible for the auxiliary crane. Furnace B of No. 2 furnace is the last cracking furnace in place. It needs to be placed in a furnace area with a width of 12 meters. It has the smallest working space and the greatest difficulty in hoisting. After many adjustments and alignments, the project team overcame many difficulties, and finally at 15:47, furnace B was firmly seated on the skirt. After the hoisting of the radiant section module of the cracking furnace is completed, the joint platform in the middle of the A furnace and B furnace of each cracking furnace will be installed first. After the transition section structure is installed, the structure around the radiant section furnace will be installed.
