天然气脱水技术现状

The Development Status of Natural Gas Dehydration Technology

天然气行业正进入快速发展的新阶段,天然气脱水有利于高效地开发利用天然气。介绍了国内目前使用的传统天然气脱水技术(包括溶剂吸收法、固体吸附法和低温分离法)的应用情况,并对近年发展起来的超音速脱水法和膜分离法进行了分析,说明了各自的优缺点。新型天然气脱水方法将逐步成为天然气脱水领域的新趋势。

Natural gas industry is entering a new stage of rapid development. Natural gas dehydration is conducive to the efficient development and utilization of natural gas. Introduces the application situations of traditional natural gas dehy- dration technologies used in China at present, including solvent absorption, solid desiccant adsorption and low temperature separation. Analyzes the supersonic dehydration method and membrane separation method which are developed in recent years, and illustrates their respective advantages and disadvantages. The new methods for dehydration of natural gas will gradually become a new trend in the field of natural ~as dehydration.
