摘　　要：收集了某石化厂在增产时不同阶段的大量数据,利用ASPEN PLUS软件对丁二烯第一萃取精馏装置进行模拟仿真,并对塔内压力、溶剂比、回流比等参数进行优化分析,得出最佳溶剂比区间为8.0~8.2,在分离效率不变的实际生产过程中,降低回流比可使装置的处理能力提高20%~30%.A large amount of data in different increasing production phases of a certain petrochemical plant were collected.The first extractive distillate device of butadiene was simulated based on ASPEN PLUS software,parameters of tower pressure,solvent ratio,reflux ratio were optimized and analyzed.The results show that the optimum solvent ratio is 8.0~8.2,and keeping the separate efficiency of the production process unchanged,to reduce the reflux ratio can increase processing ability of the device by 20%~30%.
