伴随社会经济发展步伐的不断加快,进一步促进石化产业发展步伐的不断加快,这其中炼厂干气中乙烯的有效利用至关重要,与此同时,乙烯的回收也引起了极大的重视,从某种程度来说可以大幅度提升石化经济利益,实现资源的再利用。本文中详细分析了炼厂干气中乙烯的回收及利用的技术发展现状,论述了不同分离及再利用技术的具体应用,谨以此给予理论参考。 Accompanied by the accelerating pace of social and economic development to further promote the pace of development of the petrochemical industry continues to accelerate, of which the effective utilization of ethylene in the refinery dry gas is essential, at the same time, the recovery of ethylene has also attracted great attention, from To some extent, it can significantly enhance the economic benefits of petrochemicals and realize the reuse of resources. In this paper, the current status of ethylene recovery and utilization in refinery dry gas is analyzed in detail. The specific applications of different separation and reuse technologies are discussed. Therefore, theoretical references are given.
