The Application of Dry Air Desiccating Method in Long Distance Natural Gas Pipeline

This paper emphasizes the necessity to carry out the desiccation to long distance natural gas pipeline, and introduces international desiccating techniques in long distance natural gas pipeline at present. The authors establish the dry air model and analyze the main influence factors on drying effectiveness. Taking the Zhongxian-Wuhan Gas Pipeline as an example, the paper describes the dry air desiccation technique and its application in this pipeline.
