乙烯泡点气的回收与利用

Recovery and Utilization of Ethylene Bubble Point Gas

乙烯球罐会产生乙烯泡点气,在氨制冷故障或停用时,只能返回裂解装置回收,直接影响裂解装置能耗和负荷,本文提出了另外一种将乙烯泡点气回收到乙二醇装置利用的方法,成效显著。

ethylene spherical tank will produce ethylene bubble point gas.In the event of ammonia refrigeration failure or shut down,it can only be returned to the cracking unit for recovery,which Directly affects the energy consumption and load of the cracking unit.In this paper,another method of recovering ethylene bubble gas from ethylene bubble tank to ethylene glycol plant is put forward,and the effect is remarkable.
