根据国内主要天然气的组成特点，从技术与经济角度出发，论述了天然气凝液（NGL）回收及其用作乙烯原料的可行性。以新疆柯克亚凝析气田的天然气为例，对凝液回收项目的经济效益进行了预测。结果表明，对于大部分天然气，C2+以上烃类含量高，有利于天然气凝液回收。回收的天然气凝液主要以乙烷、丙烷、丁烷为主，可直接用作乙烯原料。

According to characteristics of domestic natural gas composition, the feasibility of recovering natural gas liquids (NGL) used as ethylene feedstocks was discussed from the aspects of technology and economy. Taking natural gas from Kekeya condensate field in Xinjiang as an example, benefits of NGL recovery project were predicted. The results show that,most of natural gas has high content of hydrocarbon components above ethane, which is favor for NGL recovery. NGL is mainly composed of ethane, propane and butanes, and it can be used as ethylene feedstocks.
