Abstract

PURPOSE: To accomplish an effective removal of concentrated sulfuric acid from gases containing sulfur dioxide and sulfuric anhydride gas through condensation and removal of water and recycling of dilute sulfuric acid after absorption of sulfuric anhydride in the waste gases by sulfuric acid with a concentration of less than 55π while it is brought into contact therewith.
