Clean natural gas exploiting method

Abstract

The invention discloses a clean natural gas exploiting method which comprises the following steps of: 1) adding an ice inhibitor, 2) separating liquid from natural gas, 3) sending the gas obtained in step 2) into an open container, 4) adding alkali into the open container for regeneration, 5) separating waste slag, 6) sending the gas obtained in step 5) into another open container, 7) ventilatingand removing moisture, 8) conducting separation and purification, and 9) recycling the ice inhibitor solution. The invention has the advantages that the clean natural gas exploiting method overcomes the defects of the existing natural gas exploiting method, effectively exploits natural gas, effectively solves the problems that natural gas hydrate or ice affects the exploitation of the natural gasand that the natural gas exploitation causes environmental pollution and has high energy consumption, effectively eliminates potential safety hazards in the natural gas exploitation, significantly reduces the fixed investment, exploitation cost, energy consumption, self gas consumption, management workload and the like of the exploitation of the natural gas, and is characterized by easy implementation, safety, reliability, wide application range, easy promotion, high economic and environmental benefits and obvious safety benefits.
