Market demand
In 2005, China's ethylene production capacity was 9 million tons/year. It is predicted that in 2010 China's ethylene demand will reach 25 million to 26 million tons, and its production capacity will reach 14 million tons, which can only meet 55% of domestic demand. In 2020, China's ethylene demand will reach 37 million to 41 million tons, and the production capacity will reach 23 million tons, which can only meet 60% of domestic demand. It is tentatively predicted that by 2010 China will need to add about 8 sets of 800,000 to 1 million tons of ethylene complete sets of equipment, and by 2020 will need to add another 9 sets.
It is understood that China has approved the construction of large-scale ethylene projects are: Zhejiang Zhenhai Petrochemical 1 million tons / year ethylene project, a total investment of 23.3 billion yuan, completed in 2009; Quanzhou, Fujian 800,000 / year ethylene project, a total investment of 26.6 billion Yuan, completed in 2008; Tianjin Petrochemical 1 million tons/year ethylene project, with a total investment of RMB 20.1 billion, completed in 2008; Chengdu Chengdu 800,000 tons/year ethylene project, total investment RMB 21 billion, completed in 2010; 600,000 tons in Lanzhou The annual ethylene transformation project, with a total investment of 6.3 billion yuan, was completed in 2006; the Xinjiang Dushanzi Petrochemical 1 million tons/year ethylene project, with a total investment of 26.2 billion yuan, was completed in 2008. The ethylene projects that are being prepared in advance include Guangzhou Petrochemical's 800,000-ton ethylene project, Fushun Petrochemical's 800,000-ton ethylene project, Wuhan Petrochemical's 800,000-ton ethylene project, and Dalian's 800,000-ton ethylene project.
Build a set of one million-ton large-scale ethylene complete sets of equipment. The total investment is generally over 20 billion yuan. According to experience, equipment costs account for about 30% of the total investment, and the equipment cost for each large-scale ethylene project will reach about 7 billion yuan. Therefore, there will be equipment market demand of about 56 billion yuan during the “11th Five-Year Plan†period, and 63 billion RMB will have equipment market demand during the “12th Five-Year Plan†period.

development trend
At present, the general trend of the development of large-scale ethylene equipment in the world is that the petrochemical process technology has been continuously improved and the scale of production equipment is increasing, thereby promoting the development of petrochemical equipment. The single-line production capacity of ethylene crackers in the world has reached 1.27 million tons/year, and the single-line production capacity of polyethylene and polypropylene units has reached 500,000 tons/year. The large-scale petrochemical plant has promoted the development of technologies such as the design, manufacture, heat treatment, quality inspection, transportation, and on-site assembly of petrochemical equipment as well as the research and development of high-performance new materials; the development of petrochemical equipment and the research and development of process technology and design have become increasingly closer. The formation of proprietary and patented technologies has become a common practice and trend for foreign patent companies; mechatronics is a major trend in the development of petrochemical equipment industry. Future petrochemical equipment will be high performance, high raw material utilization, low energy consumption, and low The intelligent system of pollution, environmental comfort and recyclability; the development of energy-saving and environment-friendly petrochemical equipment to reduce energy consumption and protect the environment has become the development trend of the world's petrochemical equipment manufacturing industry; as most petrochemical equipment is at a high temperature, Operating under high pressure and corrosive conditions, the application of new materials can significantly improve the mechanical properties of the material, reduce equipment quality, reduce costs, and facilitate transportation.
