Abstract
In the production of highly concentrated sulphuric acid by the condensation of gaseous mixtures of sulphur trioxide and water vapour, the gases, at a temperature above 300 DEG C. are passed upwardly through an irrigation tower, whereby a portion of their sulphuric acid content is condensed, and are then subjected to electrical precipitation to remove their residual sulphuric acid content, the acid recovered by the precipitation being employed for irrigating the tower. In an example, a metallurgical gas containing SO2, O2 and H2O was catalyzed to SO3 by passage over a catalyst comprising vanadium oxide, potassium oxide and silica, and admitted at a temperature of 350 DEG C. to the irrigation tower wherein the gases were cooled to 100 DEG C. Two-thirds of the SO3 was precipitated in the tower, the remaining gases passing to the electrical precipitator in which the whole of the acid mist was precipitated. Sulphuric acid of 97,5 per cent concentration was obtained.
