Abstract

The invention provides a natural gas purification device, a purification system, a treatment system and an adsorbent regeneration method. Specifically, the natural gas purification device comprises a first adsorption tower, a second adsorption tower, a pre-heating unit and a heating unit. The inlet of the pre-heating unit is connected to a cold air source to receive the cold air provided by the cold air source, the outlet of the pre-heating unit is in connection with a cold blowing section inlet of the first adsorption tower, a cold blowing section outlet of the first adsorption tower is connected to a hot blowing section inlet of the second adsorption tower, and a hot blowing section outlet of the second adsorption tower is used for outputting the gas in the second adsorption tower. The heat of the gas output by the cold blowing section outlet of the first adsorption tower is reutilized, effective utilization of energy is realized, the utilization rate of energy is greatly improved, the energy consumption of the heating unit is reduced, and further energy is saved. In addition, the first adsorption tower is also effectively protected.

Description

Technical field [0001] The present invention relates to the technical field of natural gas processing, in particular to a natural gas purification device, a purification system, a processing system and an adsorbent regeneration method. Background technique [0002] Natural gas is a clean energy and chemical raw material. my country's long-distance natural gas pipelines use high-pressure gas transmission to transport natural gas to various natural gas gate stations. Each natural gas gate station decompresses the high-pressure natural gas and transports it to the downstream pipeline network. Or it can be liquefied into liquefied natural gas for users to use. [0003] Generally speaking, the feed gas from the natural gas gate station contains impurities such as water, mercury, acid gas, etc., and each impurity will have a serious impact on the natural gas pressure reduction system. For example, the moisture in natural gas and natural gas will form hydrates under certain conditions an...
