Hydrogen sulfide removal device and hydrogen sulfide removal method

摘要

A hydrogen sulfide removing section 30 for removing a hydrogen sulfide by bringing a first raw material containing a hydrocarbon and hydrogen sulfide into contact with an oil-soluble hydrogen sulfide absorbent, and containing a high-boiling hydrocarbon having a boiling point equal to or higher than the boiling point of propane A mixing section 40 for mixing a second raw material to be mixed with a hydrogen sulfide absorbent having the hydrogen sulfide absorbed in the hydrogen sulfide absorbent. It is preferable that a first separation unit 20 that separates the high-boiling-point hydrocarbon from the first raw material is further provided upstream of the hydrogen sulfide removal unit 30.
