Title:
METHOD FOR REMOVING H2S FROM GASEOUS STREAM AT NORMAL TEMPERATURE
Document Type and Number:
WIPO Patent Application WO/2010/081289
Kind Code:
A1
Abstract:
A wet desulfurizing method for removal of H2S from gaseous stream at normal temperature comprises the steps: (a) contacting and reacting the gaseous stream containing H2S with a suspension containing desulfurizer in a desulfurization reactor (4); (b) leading the suspension containing waste agent produced by desulfurizing of desulfurizer after the reaction in step (a) to a regenerative reactor (1), and regenerating the waste agent by using an oxygen-containing gas; (c) leading the suspension containing desulfurizer regenerated in step (b) to the desulfurization reactor (4) in step (a), and contacting and reacting with the gaseous stream containing H2S.
