The low-temperature diesel oil absorption oil gas recovery process recommended in the technical specification of petroleum refining industrial waste gas treatment engineering is a process route adopted by petrochemical enterprises at present. The exhaust gas absorbed by the low-temperature diesel in the route generally enters the heating furnace through an air inlet of the heating furnace for combustion. One of the important control parameters of this scheme is the total hydrocarbon content in the exhaust gas after absorption to prevent the hydrocarbon content from exceeding the lower explosive concentration limit.

The hydrocarbon content in the waste gas is mixed with air and then is burnt in a heating furnace (the required oxygen content is lower than 2%), and the concentration of combustible substances in the pipeline is required to be detected before burning through the scheme. The main problems with these three schemes are: 1. the existing catalytic combustion type combustible gas detector requires the oxygen content to exceed 10%, and the oxygen content in the absorbed waste gas is far below the value and cannot be detected; 2. the PID detector has no requirement on the oxygen content, but is limited to the characteristics of the product, the detectable range is extremely small, and the measurement requirement cannot be met; 3. chromatograph is expensive.
