According to Chen Tonghai, Zhenhai Refining and Chemical Co., Ltd.'s 1 million-tonne ethylene project has an estimated investment of 22 billion yuan. There are 10 main production plants, of which ethylene "leader" - 1 million tons / ethylene cracker is used by Sinopec and the United States ABB Lu The company's cooperation technology, the use of 800,000 tons/year pyrolysis gasoline hydrogenation, 700,000 tons/year aromatics extraction, 650,000 tons/year ethylbenzene, 300,000 tons/year polypropylene, etc Intellectual property technology.
Ethylene is known as the "mother of the petrochemical industry," and it is a basic raw material from which synthetic resins, synthetic fibers, synthetic rubber, and a wide variety of petrochemical products can be derived. In recent years, especially during the "10th Five-Year Plan" period, China's ethylene industry has developed rapidly. In 2005, its production capacity has reached 7.875 million tons, ranking second in the world.
The biggest bright spot in the development of the ethylene industry in China is the increase in size. According to Wang Tianpu, president of Sinopec, Sinopec now has an ethylene production capacity of 6.2 million tons, which accounts for more than 70% of China’s total ethylene production. The average size of a single set of equipment is 462 thousand tons, which is almost doubled compared with the early period of the “10th Five-Year Planâ€. Some time. Today, Yanshan Petrochemical, Shanghai Petrochemical, Yangzi Petrochemical, Qilu Petrochemical, Maoming Petrochemical and other large-scale ethylene have completed the second round of technological transformation, with the exception of Shanghai Petrochemical's production capacity of 650,000 tons/year, and the rest more than 700,000 tons/year.
Integration is another bright spot in the development of China's ethylene industry. According to Sun Weijun, general manager of Sinopec Zhenhai Refining and Chemicals, Zhenhai Refining and Chemical Project is a typical integrated project of refining and chemical, which will better realize mutual supply and optimization of upstream and downstream raw materials. He said that hydrogenated tailings of oil refining, reformed raffinate, and carbon, carbon, and carbon tetra components in dry gas can be very good chemical raw materials, while by-product hydrogen from ethylene cracker is a refinery. Cheap hydrogen source, methane hydrogen is a good hydrogen production of raw materials, pyrolysis gasoline, etc. have become the blending component of refined oil. The rational use of this resource and raw material configuration can effectively reduce the energy and material consumption of the integrated refinery and chemical plant, and maximize the value of oil and gas resources after processing.
Sinopec Zhenhai Refinery and Chemicals' 1 million tonne/year ethylene project broke ground today and is expected to be completed and put into production in 2009. Chen Tonghai, chairman of Sinopec, stated that the move marks China’s ability to build high-tech, world-class large-scale ethylene projects in key technologies such as patented technologies, independent design, and independent construction, marking China’s ethylene industry entering a new development. stage.
