管道干燥处于工程后期,工程施工过程及工期进度都受到管道干燥程度的影响。管道中的液体水分会导致天然气的含水量升高,从而影响供气品质下降,供气品质要求严格的用户的正常使用受到严重影响,因此本文通过对于长距离天然气的管道干燥技术进行研究,了解干空气干燥技术的广泛应用。 Pipeline drying is in the late stage of the project, the construction process and schedule are affected by the extent of pipeline drying. The liquid moisture in the pipeline will lead to the increase of the water content of natural gas, which will affect the quality of the gas supply and the normal use of users with strict gas quality requirements. Therefore, this paper studies the pipeline drying technology for long distance natural gas Dry air drying technology widely used.
