Abstract

The present invention provides an integrated process and system for detecting and treating toxic gases in deep natural gas. If it is found that the concentration of mercury, radon and hydrogen sulfide in the deep natural gas reaches the standard, the deep natural gas will be sent to the gas pipeline; , hydrogen sulfide and the remaining part of mercury are harmlessly treated sequentially; and then mercury, radon and hydrogen sulfide are detected for the deep natural gas after the harmless treatment. If the concentration of mercury, radon and hydrogen sulfide in the deep natural gas reaches the standard, there will be no The deep-layer natural gas after detoxification treatment is sent to the gas transmission pipeline; if the concentration of mercury, radon and hydrogen sulfide in the deep-layer natural gas is not up to the standard, the radon, part of mercury, hydrogen sulfide and the remaining part of mercury will continue to be harmlessly treated in sequence until Up to standard.

Description

technical field [0001] The invention relates to an integrated process and system for detecting and treating toxic gas in deep natural gas, belonging to the technical fields of oil and gas exploration, safe production and occupational disease prevention. Background technique [0002] With the expansion of oil and gas exploration to deep and unconventional fields, more and more natural gas has been discovered, developed and utilized, which has greatly eased the tense situation of natural gas supply in China. However, these deep sources and unconventional natural gas contain more or less toxic and harmful components, and some of them seriously exceed the standard, posing a threat to safe production and life and health. In the past natural gas treatment, hydrogen sulfide has attracted attention because of its abnormal smell, and many natural gas with high hydrogen sulfide content have been desulfurized. However, radon and mercury in these deep sources and unconventional types o...
