Abstract

In the preparation of sulfuric acid, a 240-330 DEG C hot gas stream containing SO3 and H2SO4-vapour in a total amount of up to 10% b.v. and up to 50% b.v. of steam, the ratio steam/SO3 being at least 1:1, is passed upwards through a plurality of externally cooled, vertical, acid resistant tubes (7) in a heat exchange tower for condensing sulfuric acid. The tubes are cooled with air introduced through an inlet opening (12) in the upper part of the tower and discharged through one or more exit openings in the lower half of the tower. By regulating cooling air velocities and levels from the bottom of the tower of discharging the cooling air the cooling is regulated so as to determine the discharge temperature T4 DEG C by the formula T4>125+6 alpha + beta +0.2(T1-Td> (where alpha is the %b.v. content of SO3+H2SO4-vapour in the feed gas, beta its % b.v. content of steam, T1 its temperature in DEG C and Td its dew point for H2SO4-vapour in DEG C). Sulfuric acid is condensed on the inner tube walls as a film of liquid flowing downwards and in contact with the hot feed gas is concentrated to 93-98% H2SO4. <IMAGE>
