简介:公开号CN1769250A公开日2006.5.10申请人中国石油化工股份有限公司共同申请人中国石油化工股份有限公司北京化工研究院本发明公开了一种从裂解气中分离烯烃和氢气的方法。该方法是将进料气送入前脱丙烷塔或前脱乙烷塔,分离得到的气相流A送入膜分离工序,分离成富氢气流C和富烃类气流B;然后将富烃类气流B送入深冷分离工序。该方法主要包括前脱丙烷(或前脱乙烷)气液分离步骤、氢烃膜分离步骤和富烃深冷分离步骤。该方法可使原料裂解气的氢回收率达20%以上,氢纯度达到95v%以上,回收的氢可直接作为加氢原料气,同时由于分离出部分氢气可减少深冷分离系统至少14.1%的冷量消耗。该工艺流程简单,操作方便,能耗低,尤其适用于乙烯工业化装置。
