ABSTRACT:
The present invention relates to a process for removing hydrogen sulfide from a hydrogen sulfide containing gas comprising contacting the gas in a contactor with an aqueous reactant solution including a coordination complex of Fe(III) with a chelating agent to produce a purified gas and spent aqueous reactant solution containing solid sulfur and having an increased content of coordination complex of Fe(II) with the chelating agent, and regenerating the spent aqueous reactant solution by contacting in a first contact vessel the spent aqueous reactant solution co-currently with air to produce partly regenerated aqueous reactant solution followed by contacting in a second contact vessel partly regenerated aqueous reactant solution counter-currently with air to produce regenerated aqueous reactant solution which is removed from the lower part of the second contact vessel.
