METHOD OF REMOVING HYDROGEN SULFIDE FROM A GAS

摘要

F5423 The present invention provides a method of removing hydrogen sulfide (H2S) from a gas by contacting the gas in a reaction zone with a reaction solution of a chelated polyvalent metal, thereby producing elemental sulfur (S), removing the elemental sulfur, regenerating the reaction solution by contacting it with oxygen produced electrolytically, and recycling the regenerated reaction solution to the reaction zone.
