| 摘 要： | 目前天然气净化中广泛应用的工艺方法绝大多数和立足于不同类型的化学反应，而从发展角度看，对若干类型特殊的原料天然气还有必要开发新型的分离过程，以进一步改善装置投资，操作成本，净化度和环境保护等方面的指标。８０年代以来，物理分离过程应用于天然气净化的势头方兴未艾，尤其是在其它工业中应用颇多的膜分离、低温分馏和变压吸附三大技术，在天然气净化中的应用也发展甚快。

| Abstract: | ??At present,most of gas purification techniques are the patterns of chemical reaction.It is necessary developing new techniques to meet the needs of separating many kinds of special unstripped gas and to improve the indexes of equipment,investment,operation cost,purification rate and environmental protection etc.Since the 1980s,physical separation methods are in the aceendent of gas purification.The applied situations of the three physical separation such as membrane separation low-temperature fractional distillation and pressure-swing adsorption are introduced. |

| Keywords: | Natural gas Membrance permeation Low temperature Fractional distillation pressure-swing adsorption method.Application Developing trend |
