摘要
文章主要介绍使用冷却镜面目测法检测天然气水露点的方法。根据现场常见问题,总结检测经验,提出检测前采用GB/T 13609取样的吹扫方式,将整个检测系统作为一个取样器,采用充气排空法将测定室及管路内的空气置换完全的改进方法。
This title mainly introduces the method of detecting the dew point of natural gas by using the cooled mirror method. According to the common problems in the field and summarizing the testing experience,it is proposed that the sampling method of GB/T 13609 is adopted in the purge before testing,and the entire testing system is used as a sampler,and the improved method of completely replacing the air in the testing room and pipeline by the method of aeration and emptying is adopted.
