Embodiment 1
[0050] Taking a natural gas pipeline with a diameter of 150mm as an example, the total length of this natural gas dehumidifier is 1575mm, and four flange ports are used. One DN150 main air inlet is connected to the natural gas transmission channel by a straight pipe inlet section, and one DN150 is used to connect the rectifier section and straight pipe output section, a DN150 gas outlet is connected by the straight pipe output section and the natural gas transmission channel, and a DN50 is used for the outlet of the liquid discharge pipe.
Embodiment 2
[0052] The natural gas dehumidification device should be installed horizontally close to the wellhead or at the beginning of the gathering and transportation pipeline after the gas production pipes are assembled. The flange connection can replace a section of the delivery pipeline, and the installation is simple and convenient; the outlet of the liquid collection container is transported to the liquid storage tank through the infusion pipeline for further processing.
Embodiment 3
[0054] The on-site natural gas pipeline pressure is 3MPa, the gas temperature is 30 degrees Celsius, the actual measured pressure drop loss is about 20%, and the free liquid components can be separated by more than 95% after being treated by the natural gas dehumidification device, eliminating the liquid components in the pipeline transportation process Hazard of hydrate formation, freezing, clogging at elbows.
