摘要
截至2002年年底,我国乙烯生产能力已经达到555.5万吨/年,居世界第四位;2002年共生产乙烯541.33万吨,但自给率仅为41.9%。未来几年随着我国经济的持续快速发展,对乙烯的需求将进一步增加,预计到2010年国内乙烯的需求当量将达到2032万吨。目前,我国乙烯工业还存在诸多不足,如装置规模小,综合利用率低;原料重,物耗、能耗高;国产化程度低,自我开发创新能力差;产品结构不合理,专用料比例低等。下一步我国乙烯工业发展的重点是扩能改造现有乙烯装置,规划建设好大型乙烯项目,并坚持炼化一体,大力开发副产品综合利用技术等。未来我国乙烯的发展有可能遇到原料进一步变重及不足的问题,对此我们需要及早研究。如果简单地将原料缺口寄希望于通过进口解决,可能要付出很高的代价,而且保证程度也将会受到影响。因此,应立足于国内,配合乙烯发展,规划好炼油厂扩建改造,最大限度地提供乙烯原料。同时,要利用好天然气轻烃资源,继续做好原料的轻制化工作。
As of the end of 2002, China had an ethylene production42Acapability of 5.555 million tons per year,ranking her fourth highest in the world. The country actuallyproduced 5.4133 million tons of ethylene in 2002, but ratedits self-sufficiency level at only 41.9 percent. China’sdemand for ethylene will further rise with the rapid andsustainable economic development of the country over the nextfew years. The domestic ethylene demand is expected to reach20.32 million tons by 2010. There are a number of shortcomingsin the country’s ethylene industry at present, such as smallscale facilities, low comprehensive utilization rates, heavyraw materials, inefficiently high consumption of energy andmaterials, a low degree of localization, a lack of self-development and innovation, unreasonable product structure,and a low proportion of specialized products. China’s ethyleneindustry should focus on expansion of productivity and therenovation of existing facilities, while at the same timeworking on plans for the construction of large-scale ethyleneproduction facilities. Great efforts need to be made to refinechemical integration processes and to develop technologiesfor the comprehensive utilization of by-products. As it develops, China’s ethyleneindustry is likely to face a shortage of rawmaterials. It is necessary for us to studythis issue as soon as possible. It will be costly in thelong run to relieve the shortage simply by importing neededmaterials. The country’s ethylene industry should utilizedomestic resources and formulate plans for expansion andrenovation of refineries to ensure an adequate supply of rawmaterials for ethylene production. Meanwhile, it is necessaryto make effective use of light natural gas hydrocarbon resourcesand to continue lightening of raw materials.
