高压聚乙烯在役老装置高能耗原因分析及对策

摘要

In view of the fact that the 1^# LDPE plant is an old on - service plant characterized by small production scale and unadvanced processing conditions, based on comparison with the newly built 2^# LDPE plant, the causes of gap in comprehensive energy consu%针对1号高压聚乙烯在役老装置生产规模小，工艺技术条件陈旧等状况，通过与后续建成投产的2号高压聚乙烯装置进行比较，剖析了其与先进装置存在综合能耗差距的原因；从节电和节约蒸汽等方面，提出了该装置节能降耗的对策；通过实施优化改造，使装置综合能耗（标油）减少70．81kg／t，取得良好的经济效益。
