Natural gas purification and dehydration device

Abstract

The invention discloses a natural gas purification and dehydration device, which comprises a first filtering device, a second filtering device and a third filtering device, the first filtering deviceis used for preliminarily filtering gas, and condensate or liquid drops contained in natural gas can be preliminarily removed while solid particle impurities contained in the natural gas are removed;the second filtering device can conduct secondary filtering on the natural gas, further conduct gas dehydration and remove residual water vapor in the gas, the third filtering device can conduct tertiary filtering on the gas, impurity gas is removed while the residual water vapor is removed, and purification and dehydration of the natural gas are achieved. According to the technical scheme, the design of a first air outlet pipe and a second air outlet pipe is used for achieving communication among the first filtering device, the second filtering device and the third filtering device; accordingto the technical scheme, structural design is reasonable, operation is easy, the purification and dehydration effect of natural gas is effectively achieved, dehydration efficiency is improved, and high practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of gas purification, in particular to a natural 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 purificat...
