据中国国家统计局数据显示,2012年,我国全年乙烯产量约1 490万t,同比下降2.4%,继2008年以后历史上第二次下降。全年乙烯开工率93.5%,与过去几年接近100%的开工率相比,2012年中国乙烯工业的开工率明显下降。全年乙烯开工率呈先降后升的走势,基本在90%～95%之间。三季度开工率一度跌破90%,但四季度开工率止跌回升。2013年,随着四川、武汉等大乙烯的建成投产,我国将新增乙烯产能220万t/a,同比增长12.9%,产能将达到1 929.5万t/a。预计乙烯年产量将进一步上升并突破1 600万t。
According to data from the National Bureau of Statistics of China, ethylene production in China for the year was estimated at about 14,090,000 tons in 2012, down 2.4% from the same period of last year and the second decline in history after 2008. The operating rate of ethylene in the whole year was 93.5%. Compared with the operating rate close to 100% in the past few years, the operating rate of ethylene in China decreased significantly in 2012. The annual operating rate of ethylene was the first drop after the rise, the basic 90% to 95%. Operating rate in the third quarter fell below 90%, but the operating rate in the fourth quarter rebounded. In 2013, with the completion of the large-scale ethylene production in Sichuan and Wuhan, China will add 2.2 million t / a of ethylene capacity, an increase of 12.9% over the same period of last year and its production capacity will reach 19.295 million t / a. It is estimated that the annual output of ethylene will further rise and break through 16 million tons.
