Abstract
METHOD AND PLANT DESIGN TO REDUCE INITIAL SULFUR OXIDE EMISSIONS IN SULFURIC ACID PRODUCTION. The invention is a method and a sulfuric acid plant design for the reduction of SO2, SO3 and H2SO4 emissions at the start of sulfuric acid production, where SO2 is converted to SO3 in n successive catalyst beds, where n is a integer > 1. The final catalytic beds are used as absorbers of SO2 to SO3 during the start-up procedure, and one or more of the beds downstream of the first bed are purged, separately or simultaneously, with hot gas, where m is an integer > 1 and m n, during the previous shutdown. In addition, a separate hot gas purge is used in the final bed.
