On the morning of July 25, the inauguration ceremony for the 400,000 tons per year high-density polyethylene production unit as part of Jilin Petrochemical’s refining and chemical industry transformation project was held at the construction site. The 400,000 tons per year high-density polyethylene project, part of Jilin Petrochemical Company’s refining and chemical industry transformation initiative, was designed by CNPC Jilin Chemical Engineering Co., Ltd., with CNPC Jilin Chemical Construction Engineering Co., Ltd. acting as the joint general contractor. The entire project consists of a polymerization reaction and external circulation cooling framework, a powder handling and recycling framework, a compressor area, a powder storage framework, powder transfer stations, hexane/mother liquor tank areas, underground piping networks, power supply lines and road lighting, telecommunications lines, as well as utility systems within the general layout, transportation areas, and plant boundaries. The Jilin Petrochemical Refining and Chemical Transformation Project, with a total investment of 33.9 billion yuan, is the largest single industrial project in Jilin Province. It will help transform Jilin Petrochemical from a company focused on fuel production to one that specializes in chemical products and organic materials. The project includes the construction of 21 petrochemical units with an annual production capacity of 1.2 million tons of ethylene and 600,000 tons of ABS, the renovation of 9 units, and the shutdown of 7 units including one with an annual ethylene production capacity of 150,000 tons. Jilin Petrochemical’s current total oil refining capacity is 9.8 million tons per year. Upon the implementation of this project, the refining division of Jilin Petrochemical will adjust the types of crude oil processed, while keeping the total processing capacity unchanged. New facilities will be built, including a 2.2 million tons per year wax oil hydrocracking unit (including a 300,000 tons per year naphtha normal and isomer separation unit), a 1 million tons per year diesel adsorption unit, and a 300,000 tons per year C2 recovery unit. The existing Unit I atmospheric and vacuum distillation unit is retrofitted in a different location, with the crude oil processed there being replaced by Russian crude; meanwhile, Unit II atmospheric and vacuum distillation unit is adapted to process Qingdao/Jilin crude oil ； The 900,000 tons per year hydrocracking unit has been converted into a catalytic diesel hydrogenation and upgrading unit; while maintaining its crude oil processing capacity, it now uses straight-run diesel as raw material and no longer processes wax oil ； Environmental improvement of a 1 million tons/year delayed coking unit ； The solvent regeneration system of the III sulfur recovery unit in the 20,000–20,000 tons/year sulfur recovery complex was adapted to enable a processing capacity of 240 tons per hour, while the II catalytic cracking unit was shut down. The chemical processing section will feature a new ethylene plant with an annual production capacity of 1.2 million tons. Downstream, facilities will be built for the hydrogenation of pyrolysis gasoline at 1 million tons per year, a combined aromatics extraction plant at 450,000 tons per year, a high-density polyethylene plant at 400,000 tons per year, an ethylene oxide plant at 300,000 tons per year, an EVA plant at 400,000 tons per year, a phenol propylene plant at 350,000 tons per year, a bisphenol A plant at 240,000 tons per year, an EPDM plant at 40,000 tons per year, an MTBE/1-butene plant at 100,000/40,000 tons per year, a styrene plant at 600,000 tons per year, an acrylonitrile plant at 260,000 tons per year, an ABS plant at 600,000 tons per year, a solvent deasphalting plant at 800,000 tons per year, an asphalt gasification plant at 160,000 tons per year, a SBR plant at 50,000 tons per year, a butadiene extraction plant at 200,000 tons per year, and an acetonitrile plant at 8,000 tons per year. Once the project is completed and put into operation, Jilin Petrochemical Company’s crude oil processing capacity will remain at its current level; the strategy of \"reducing oil production and increasing chemical product production\" will yield significant results, with 2.63 million tons of oil products being reduced annually and approximately 2.8 million tons more of chemical products being produced. The total ethylene production capacity reaches 1.9 million tons per year ； The production capacity of key chemical products such as ABS resin, acrylonitrile, and methyl methacrylate is among the highest in China ； The scale advantages of ethylene-propylene rubber, styrene, and high-density polyethylene are fully utilized ； New products such as EVA, bisphenol A, and cis-butadiene rubber have been added, helping to further extend the industrial chain and make the product structure more rational. Establish an industrial layout and product structure that reflect the characteristics of Jilin Petrochemical and offer competitive advantages in the market, thereby moving toward the higher end of the industrial chain.
