摘要： A method is disclosed for reducing the sulfur deposition in the absorber of a Stretford process. In the Stretford process, hydrogen sulfide is removed from a gas stream by contacting the gas stream in an absorber with a circulating aqueous solution to convert the hydrogen sulfide to elemental sulfur particles, passing the solution containing the sulfur particles to a reaction vessel where the conversion of hydrogen sulfide to sulfur is completed, passing the solution containing the sulfur particles to an oxidizer, oxidizing the solution containing the sulfur particles in the oxidizer to form a regenerated solution, separating the sulfur particles from the regenerated solution, and recirculating the solution to the absorber. The sulfur deposition in the absorber is reduced by adding about 300 ppm of a hydroxyquinone compound, such as 1-hydroxyanthraquinone (1-HAQ); 1,2-dihydroxyanthraquinone (1,2-DHAQ); 1,8-dihydroxyanthraquinone (1,8-DHAQ); 1,2-dihydroxyanthraquinone 3-monosulfonic acid (1,2-DHAMA); 1,2,5,8-tetrahydroxyanthraquinone (1,2,5,8-THAQ); 1,4,5,8-tetrahydroxyanthraquinone (1,4,5,8-THAQ); 5- hydroxy 1,4-naphthoquinone (5-HNQ); or a mixture thereof, to the absorber.
