SYSTEM FOR REMOVING HYDROGEN SULFIDE AND METHOD FOR REMOVING HYDROGEN SULFIDE

摘要

A system 1 for removing hydrogen sulfide, which is characterized by comprising: a hydrogen sulfide separation device 30 which separates a starting material gas containing hydrocarbon and hydrogen sulfide into a first gas that has a lower hydrogen sulfide concentration than the starting material gas and a second gas that has a higher hydrogen sulfide concentration than the starting material gas; and a sulfuric acid production device 50 which produces sulfuric acid with use of the second gas.
