摘　　要：目前,国内天然气行业正进入高速发展的历史新格局,天然气的高效开发和利用已成为未来能源发展的新课题。所以,未来天然气高效脱水技术将是一个重要的研究方向。现阶段工业上天然气脱水方法主要有:三甘醇脱水(TEG)、分子筛脱水、低温脱水。近年来膜分离和超音速这两种新型技术正日益受到人们的关注,发展迅速。这两种新技术在天然气脱水方面具有结构简单、能耗低、运行维护费用小、操作简单、污染小等特点。从根本上弥补了以往天然气脱水技术系统复杂、体积庞大、高能耗、维护费用高、污染大的特点。未来以膜、超音速脱水为代表的新技术将会有很大的发展空间。At present, domestic natural gas industry is entering a stage of rapid development, and efficient development and utilization of natural gas has become a new topic of future energy development. The highly efficient gas dehydration technology is an important part of the effective use of natural gas. Now industrial gas dehydration methods include TEG dehydration（TEG）, molecular sieve dehydration and low temperature dehydration. In recent years, the membrane separation and supersonic method are drawing people＇s attention. These two new technologies have many characteristics, such as simple structure, low energy consumption, low operation and maintenance cost, and low pollution. The new film and supersonic dehydration technologies will be a great space for development.
