Integrated gas purification dehydration device

Abstract

The invention discloses an integrated gas purification dehydration device, which comprises a first filtering unit, a second filtering unit and a third filtering unit. The first filtering unit is usedfor preliminary gas filtration to remove solid particle impurities contained in natural gas and preliminarily remove condensate or liquid drops contained in the natural gas at the same time; the second filtering unit can perform secondary filtration on the natural gas for further gas dehydration and removal of residual water vapor in the gas; the third filtering unit can perform tertiary filtration on the gas to remove residual water vapor and impurity gas at the same time, thus realizing purification dehydration of the natural gas. According to the technical scheme, the design of a first airoutlet pipe and a second air outlet pipe is used for achieving communication of the first filtering unit, the second filtering unit and the third filtering unit. According to the technical scheme, thedevice provided by the invention has reasonable structural design, is easy to operate, not only effectively realizes the purification dehydration effect of natural gas, but also improves the dehydration efficiency, and has high practicability.

Description

technical field [0001] The invention relates to the technical field of gas purification, in particular to an integrated gas purification and dehydration device. Background technique [0002] As a clean, efficient and convenient high-quality fuel and an important chemical raw material, natural gas has a wide range of applications, but the composition of the wellhead natural gas exploited today is very complex, and it needs to go through a series of processing before it can enter the pipeline for transportation . [0003] In the process of natural gas processing, it is first necessary to dehydrate natural gas to avoid the corrosion of acid gas on pipeline equipment in the presence of someone, and to avoid the formation of hydrates to block pipelines. However, for the problem of natural gas dehydration, the current dehydration effect is poor , the work efficiency is low, which brings us inconvenience. [0004] In response to this situation, we designed an integrated gas purif...
