摘要
兰州化学工业公司 16万 t/a乙烯装置自开车以来 ,因分离系统脱甲烷塔通过能力低、乙烯损失大而成为制约乙烯生产的瓶颈。本文介绍了应用 PRO-II软件对乙烯装置脱甲烷系统进行的流程模拟计算过程 ,分析了存在的问题 。
The poor pass through ability of the demethanizing tower in the separation system and the great ethylene loss have become bottlenecks in the ethylene production since the startup of the 160 000 t/a ethylene in Lanzhou Chemical Industrial Corporation. Process simulation for the demethanizing system conducted by using PRO II simulator is described in the paper. Existing problems are analyzed and proposals for improvement are also given.
