Description
Here, "hydrogen sulfide tail gas, for recovery" refers to hydrogen-sulfide-containing gas discharged by reaction or purification units and not fully recovered and utilized during oil refining, coal chemical processing, natural gas treatment, coking or desulfurization processes, typically accompanied by small amounts of other sulfides and inert gases. When such hydrogen sulfide tail gas has no direct value in use or is regarded as an emission gas, it must be discharged to standard after combustion conversion, catalytic oxidation or further desulfurization treatment, or, where conditions permit, enter a sulfur recovery unit to achieve resource recovery.

Process Description
The "hydrogen sulfide tail gas for recovery" here refers to the hydrogen sulfide-containing gas that is discharged from the reaction or purification unit during the oil refining, coal chemical industry, natural gas processing, coking or desulfurization process and is not fully recycled. It is usually accompanied by a small amount of other sulfides and inert gases. When this type of hydrogen sulfide tail gas has no direct utilization value or is regarded as an emission gas, it needs to undergo combustion conversion, catalytic oxidation or further desulfurization treatment before reaching the emission standard, or enter a sulfur recovery device for resource utilization when conditions are met.
