The invention relates to a method for recovering petrochemical engineering output gases with advantages of strong applicability, low energy consumption and high product purity. The method has excellent wide applicability, is applicable to gas by-products produced in petrochemical processing procedures such as catalytic cracking, pyrolysis, catalytic reforming, isomerization and the like, and realizes high-efficiency recovery of hydrogen, carbon monoxide, methane, ethylene, ethane and the like in chemical gases. Moreover, absorbents and refrigerants are recycled, and the economic value is high. 本发明涉及一种应用性强、能耗低、产品纯度高的石油化工产出气体的回收处理方法。该方法具有很好的广泛应用性，可适用于催化裂化、裂解、催化重整、异构化等石油化工加工过程中产出的气体副产品，实现了高效回收化工气体中的氢气、一氧化碳、甲烷、乙烯、乙烷等气体，并且对吸收剂、制冷剂进行了循环利用，经济价值高。
