摘要
天然气管道干燥是输气管道建设中的重要环节,国内外常用干燥方法有干燥剂法、流动气体蒸气法(干空气法、氮气法、天然气法等)和真空干燥法。文章介绍了这些方法的基本原理、各自的优缺点,并将它们进行了比较。国内外的应用实例表明,在长距输气管道的干燥技术领域,我国和国外还存在明显的差距。
Drying natural gas pipeline is an important part in the construction of gas pipeline.The drying methods used in domestic and overseas were desiccating agent method,the gas vapor flow method（dry air method,nitrogen gas method,natural gas method,etc.） and vacuum drying method.The paper described the basic principles of these methods,their advantages and disadvantages,and comparison of these methods.The using examples in the world show that there is still significant distance of drying method in the area of long-distance gas pipeline.
