Fremgangsmåte og anordning for behandling av en gass inneholdende nitrogensulfid, med resirkulering av den reduserte katalytiske opplösning

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...

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.
