Abstract

The invention relates to a natural gas dewatering device. A net gas outlet of a first filter separator is connected with an inlet of a molecular sieve dewatering tower, and an outlet of the molecular sieve dewatering tower is connected with an external conveying dry gas pipeline; one end of a heating inlet pipe is connected with the external conveying dry gas pipeline, and the other end of the heating inlet pipe is connected with an opening of the molecular sieve dewatering tower; one end of a cold blowing pipe is connected with the external conveying gas pipeline, and the other end of the cold blowing pipe is connected with an opening of the molecular sieve dewatering tower. When the natural gas is dewatered, the natural gas to be treated only needs to be sequentially introduced into the first filter separator and the molecular sieve dewatering tower; the dewatered and heated natural gas is introduced into the molecular sieve dewatering tower to dry molecular sieve balls, and then the dewatered natural gas is introduced into the molecular sieve dewatering tower to cool the molecular sieve balls, so that the water absorption of the molecular sieve balls is restored.

Description

technical field [0001] The invention relates to a natural gas treatment device, in particular to a natural gas dehydration device. Background technique [0002] During the development of large-scale oil and gas fields, some remote and scattered gas wells have not been utilized due to reasons such as unrealized reserves, small production, or remote location of the gas wells. Some wells are shut down, and some are vented and burned. Today, with the increasing calls for environmental protection, such waste is astonishing, and the pollution to the environment is also extremely serious. [0003] For low-yield oil and gas well natural gas in remote and scattered areas where it is difficult to lay pipelines or be utilized locally, it is recommended to develop by adopting a small mobile compressed natural gas (CNG) cylinder storage and transportation solution. [0004] Before storage and transportation, natural gas needs to be treated with impurity removal and dehydration; in the p...
