摘　　要：本文基于国能宁夏煤业集团Novolen气相法聚丙烯工艺中的丙烯精制系统,针对再生过程氮气消耗量大、脱附丙烯难以回收的问题,提出三种优化改造方案,其中,再生氮气循环+压缩深冷组合工艺不仅能够大幅降低氮气消耗量,而且对脱附产生的丙烯气体进行回收。由此实现了资源的合理化利用,提升了装置的盈利能力,具有显著的经济效益和社会效益。This paper is based on the propylene refining system in the Novolen gas-phase polypropylene process of Guoneng Ningxia Coal Group. Aiming at the problem of large nitrogen consumption in the regeneration process and difficult recovery of desorbed propylene, three optimized transformation schemes are proposed. Among them, regeneration nitrogen cycle and compressed cryogenic combined process can not only greatly reduce nitrogen consumption, but also recover propylene gas produced by desorption. As a result, the rationalized utilization of resources is realized, the profitability of the device is improved, and it has significant economic and social benefits.
