摘要
目前,全世界的苯乙烯生产从融洽整体来看是有些过剩。但是近年来,亚洲特别是中国苯乙烯的消费量逐年上升。预计我国到2005年苯乙烯的消费量将达到420×104t,届时其生产能力只有约290×104t/a,因而仍须大量进口。随着生产苯乙烯的CDTECH技术、“SmartSM”技术、裂解汽油抽提蒸馏回收法等世界先进技术的进展,我国应加快自有技术的研发。具体做法是可以通过改造和新建装置增加苯乙烯的生产能力,特别是有条件的企业应充分利用炼油厂的干气资源和乙烯裂解汽油中的苯乙烯资源,以满足市场需求。
The worldwide styrene capacity has superabounded as a whole. However,styrene consumption in Asia,especially in China,keeps increasing in recent years. China will consume about 4.2 million tons of styrene in 2005,while the corresponding styrene productivity ofChina will be only 2.9 million tons per year. So,a large amount ofstyrene has to be imported. China should closely follow the development of worldwide styrene technology,such as CDTECH technique,“Smart” technique and distillation technique of pyrolysis gasoline. Moreover, China should quicken the research of own styrene technology,increase styrene capacity by building new settings or expanding existing devices and fully utilize dry gas produced from refinery and the styrene resource in pyrolysis gasoline to satisfy domestic market demand.
