Process and apparatus for treatment of a gas containing hydrogen sulfide with recycling of the reduced catalytic solution

A gas is desulfurized by contacting a catalytic solution including a chelated polyvalent metal that oxidizes the hydrogen sulfide to sulfur. The metal is reduced to a lower oxidation state. The sulfur remains in the solution An Independent claim is included for a plant for desulfurizing having enclo...

More Information
Summary:A gas is desulfurized by contacting a catalytic solution including a chelated polyvalent metal that oxidizes the hydrogen sulfide to sulfur. The metal is reduced to a lower oxidation state. The sulfur remains in the solution An Independent claim is included for a plant for desulfurizing having enclosure(s) for contacting the gas with the solution, devices for removing the treated gas and the used solution from the enclosure(s), a regulator controlling the amount of the used solution recycled to the enclosure(s) and a regulator controlling the grain size of the sulfur.
