Abstract
Procedure for the preparation of sulfuric acid by catalytic transformation of SO2 into SO3 in various catalysis beds, cooling between the catalysis beds of gases containing SO3 and absorption of 30, in sulfuric acid, characterized by the combination of the following steps: a) combination of the preparation of sulfuric acid with a treatment of dilute sulfuric acids containing salts, b) splitting of the resulting sulfates in the treatment, and eventually splitting of at least a part of the resulting diluted, treated sulfuric acid, c) carrying out SO3 absorption from catalysis gases from catalysis as hot absorption at working temperatures of 100 - 200ºc, d) expulsion of water from dilute sulfuric acids containing salts, by direct catalysis with hot gases, which they consist of the final gas from the catalysis and/or inert gases that are poor in water, which are heated with heat from the syst catalysis ema, e) and possibly simultaneous contribution of thermal energy from the hot acid of the absorber and/or the acid from the dryer of the catalysis system, by indirect heat exchange with the diluted sulfuric acids containing salts.
