Abstract

This invention relates to a process and an apparatus for producing concentrated sulfuric acid by means of an absorption tower. To absorb large amounts of S03 (or H2O) in sulfuric acid of different concentration, it is proposed that an empty tube is integrated inside a packed absorber, wherein the gas and the acid are introduced at the head of the empty tube and are cocurrently passed into the lower portion of the succeeding packed absorber, subsequently the gas is passed upwards through the packing, further acid is introduced into the packed absorber above the packings and is countercurrently mixed with the gas in the packing region, the gas from the head of the packed absorber being withdrawn and the acid being discharged from the bottom of the packed absorber.
