Abstract

The invention discloses a double-column adsorption purification process for natural gas. A device comprises: an adsorption pipeline, a communication pipeline, a conveying pipeline and an electrical cabinet, wherein two ends of the communication pipeline are respectively communicated with the adsorption pipeline and the conveying pipeline; an electronic one-way valve is mounted on the adsorption pipeline; an adsorption module and a moisture detection probe are arranged in the adsorption pipeline; the moisture detection probe is connected with the electrical cabinet through a data line; and theelectrical cabinet is connected with the electronic one-way valve through a data line. According to the device, through the disconnected connection of the adsorption pipeline and the conveying pipeline, when the molecular sieve in the adsorption pipeline is regenerated, the standby adsorption pipeline can be connected to the conveying pipeline; therefore, the regeneration process of the molecularsieve does not influence natural gas transportation.

Description

technical field [0001] The invention relates to an adsorption purification process, in particular to a natural gas double-tower adsorption purification process, which belongs to the application field of natural gas equipment. Background technique [0002] Due to the increasingly serious pollution caused by coal and oil resources to the natural world, as the concept of green, environmental protection and sustainable development is highly respected, people's calls for new energy are getting louder and louder. Clean fuels are much favored by people. [0003] In the process of natural gas adsorption and purification, as the moisture absorbed by the molecular sieve in the adsorption tower increases, the adsorption capacity of the molecular sieve to water molecules gradually decreases. When it reaches a certain value, the molecular sieve in the adsorption tower is saturated. At this time, the molecular sieve in the adsorption tower must be regenerated. [0004] However, the exis...
