Method and apparatus design for reducing start-up emissions of sulfur oxides in sulfuric acid production

Applicants

Abstract

The invention relates to a method for reducing SO in sulfuric acid production₂、SO₃And H₂SO₄Start-up emission method and sulfuric acid plant design of (1), wherein SO₂Conversion to SO in n successive catalyst beds₃Wherein n is an integer greater than 1. The last catalyst bed is used as SO during the start-up procedure₂And SO₃And during a preceding shutdown, one or more of the m beds downstream of the first bed are purged, either separately or simultaneously, with hot gas, where m is an integer greater than 1 and m is<n is the same as the formula (I). In addition, a separate purge with hot gas is used on the last bed.
