摘　　要：介绍了炼油厂干气中目前使用的深冷法、吸收法、水合物分离法、膜分离法、吸附分离法等烯烃分离技术。其中深冷法和吸收法投资大,生产成本高;水合法得到的产品纯度低;膜分离法中使用的膜的寿命通常少于1年;变压吸附法具有清洁、低能耗等优点,适合炼油厂干气中烯烃的分离,具有良好的应用前景。Technologies used for separating alkene from dry gas are reviewed,which include cryogenic method,absorption,hydrate separation,membrane separation and adsorption separation.The investment of cryogenic method and absorption is comparatively high.The purity of product obtained from hydrate separation process is low.Life of membrane used in membrane separation process is usually less than one year.The pressure swing adsorption considered as a clean and low cost technology is a promising technology applied in alkene separation from dry gas.
