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 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; 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.
