摘　　要：随着天然气在能源消费中的比重越来越大,天然气集输过程中的液态水及烃质等杂质的不利影响受到广泛的关注。本文对天然气的液态水与烃质的分离进行了调研。结果显示,目前,天然气脱水的主要方法有以下几种:冷却分离技术、固体吸附技术、溶剂吸收技术、膜法分离技术以及超音速分离技术,使用较为广泛为膜分离技术与超音速分离技术。天然气脱烃的主要方法是节流分离技术和吸附分离技术。另外,丙烷压缩制冷技术在天然气脱水脱烃也有广泛的应用。With the proportion of natural gas in energy consumption is growing, the adverse effect of impurities in natural gas gathering and transportation process is paid wide attention. In this paper, separation of liquid water and gas hydrocarbon impurities from natural gas was investigated. The results show that, at present main methods of natural gas dehydration are as follows： cooling separation technology, solid adsorption technology, solvent absorption technology, membrane separation technology and supersonic separation technology. Application of the membrane separation technology and the supersonic separation technology is wider. Main methods of natural gas dealkylation include the throttling separation technology and adsorption separation technology.
