Title:
INTEGRATED PROCESS AND SYSTEM FOR MEASUREMENT AND TREATMENT OF TOXIC GASES IN DEEP NATURAL GAS
Document Type and Number:
WIPO Patent Application WO/2022/105548
Kind Code:
A1
Abstract:
An integrated process and system for measurement and treatment of toxic gases in deep natural gas. The process comprises: cooling and depressurizing deep natural gas and then drying same; sequentially performing radon, hydrogen sulfide, and mercury measurements on the dried deep natural gas; if it is found after the measurements that the concentrations of mercury, radon, and hydrogen sulfide in the deep natural gas reach standards, delivering the deep natural gas to a gas transmission pipeline; if it is found after the measurements that the concentrations of radon, hydrogen sulfide, and mercury in the deep natural gas are substandard, sequentially performing harmless treatment on radon and partial mercury, hydrogen sulfide, and remaining mercury in the deep natural gas; sequentially performing mercury, radon, and hydrogen sulfide measurements on the deep natural gas having experienced the harmless treatment; if the concentrations of mercury, radon, and hydrogen sulfide in the deep natural gas reach the standards, delivering the deep natural gas having experienced the harmless treatment to the gas transmission pipeline; and if the concentrations of mercury, radon, and hydrogen sulfide in the deep natural gas are substandard, continuing to sequentially perform harmless treatment on radon and partial mercury, hydrogen sulfide, and remaining mercury in the deep natural gas, until the concentrations thereof reach the standards.
