Abstract: The technological process for the separation of methylcyclopentane from raffinate oil was studied. Simulated by Aspen Plus software，the optimum design parameters，operating condition，heat duty of condenser and heater were obtained for common distillation. The separation of methylcyclopentane with methanol as entrainer in azeotropic distillation was also simulated. Meanwhile，the optimum design and operating condition of the azeotropic distillation column for methylcyclopentane were obtained.

摘要： 研究了从芳烃抽余油中分离甲基环戊烷的方法和流程，首先用Aspen Plus软件模拟了精馏法提取甲基环戊烷的分离结果。通过模拟计算得到了最优的设计参数、操作条件、各塔冷凝器、再沸器的热负荷。在此基础上，还模拟了用甲醇作共沸剂共沸精馏分离得到甲基环戊烷的结果，获得了最优的设计参数和操作条件。
