Abstract
Procedure for the production of sulfuric acid from wet gases, containing SO2, by catalytic transformation of the content of SO2 into SO3, direct cooling of the wet gases, containing SO3, with an aqueous medium, condensation of sulfuric acid in the gases cooled by indirect cooling below the dew point of sulfuric acid, and evacuation of water not necessary for the formation of sulfuric acid, as water vapor with the final gases, characterized in that the direct cooling of the humid gases containing SO3 is carried out at 190-270ºC in a vertical Venturi in isocurrent with diluted sulfuric acid injected, a part of the sulfuric acid is separated in a collecting tank below the outlet end of the Venturi, the gases are led from the Venturi to a settling space, there another part of the sulfuric acid is separated in a collecting tank, the cooled gases from the settling space are conducted To a condenser, the sulfuric acid separated there by condensation in the indirect cooling is led to the separated sulfuric acid in the Venturi and in the settling space, after cooling, a production is removed from a amount corresponding to that of the newly formed sulfuric acid, and the remainder of the cooled sulfuric acid is injected back into the Venturi.
