Abstract

Procedure for the separation of the sulfuric acids contained in the exhaust gases of the sulfuric acid facilities; operating according to the wet catalysis system, these facilities where the gases containing hydrogen sulfide are burned and in which sulfur trioxide is being absorbed from the combustion gases in the form of sulfuric acid, while the remaining gases are separated, in a mechanical or electrical way, the referred acid mists; characterized by the fact that the remaining gases are being mixed with cold air before they effect their entry into the separation device.
