摘　　要：随着丙烯和聚丙烯生产工艺的多元化、大型化、一体化,间歇式小本体聚丙烯聚合装置生存空间越来越小。本文分析了小本体聚丙烯工艺和SPG(丙烯“液相本体聚合+卧式釜气相聚合”组合)聚丙烯工艺在丙烯单耗、能耗、人工成本等方面的差距,并阐述了变压吸附技术、不同催化剂、自动化控制、外循环撤热、停用溴化锂制冷等措施的应用效果,来降低小本体装置生产成本。The survival space of the batch bulk polypropylene process is becoming smaller and smaller,alone with the diversification,large-scale and integration of propylene and polypropylene processes.The disparity of propylene consumption,energy consumption and labor cost between batch bulk polypropylene and SPG(combination of liquid phase bulk polymerization and horizontal kettle gas phase polymerization)was analyzed,and the application of pressure swing adsorption technology,catalysts with different characteristics,automatic control,external circulation heat exchange and shutdown of lBr chiller were described,which can reduce the production cost of batch bulk polypropylene.
