Abstract

Systems and methods of removing sulfur from a gas stream comprising hydrogen sulfide (H2S) is provided. The systems and methods may utilize iodine to remove sulfur from the gas stream. In certain systems and methods, the iodine may be regenerated. In particular, the present systems and methods may be capable of reducing sulfur content in a gas stream comprising hydrogen sulfide H2S gas to levels that are undetectable.
