摘　　要：介绍了根据中原油田文23块气田天然气特点(高压、产量稳定、甲烷含量高、不含H2S和Hg、CO2含量低等)设计的国内第一座商业化运营的LNG生产厂的情况。该厂在设计时对三种液化方案进行了对比优选,最终选用了"丙烷预冷+乙烯预冷+节流"的方案。该方案具有收率高、运行可靠、操作灵活性强等优点,对国内其他油气田建设LNG工厂具有借鉴意义。This paper introduces the LNG production factory designed by zhongyuan oil field, which is the first commercialization operation LNG production factory in China. By comparing and optimizing three kinds of liquefaction process, one process is selected which is 'propane precoolling + ethylene precoolling +throttling'. That process has some characteristics such as high recovery rate, good operational reliably and good flexibility, it can be used to direct the building of LNG factory in other oil and gas field.
