摘　　要：利用Aspen plus(version:11.1)软件对双塔精馏流程中单体脱轻脱水塔内的塔板上气相液相中水和阻聚剂对叔丁基邻苯二酚(TBC)的质量分数进行模拟计算和分析,发现如果用带侧线采出的复杂精馏塔代替传统的两个简单塔,与双塔流程相比能够在保证产品质量的基础上节省约23.63%蒸汽消耗和22.62%的冷冻水消耗。该流程在640t/a异戊橡胶中试装置上得到进一步验证。Abstract： In this paper Aspen plus is used to simulate and analyze the content of water and inhibitor TBC in vapor and liquid phase above each column plate of the light component and water removal tow- er, and it comes to the conclusion that a single side-draw complex tower can replace the traditional two simple towers. Compared with the two-tower process, the new process can save about 23. 63% of steam consumption,and 22. 62% of the chilled water consumption on the basis of quality assurance of product. The process has been verified in Jihua 640t/a isoprene rubber pilot plant.
