Zusammenfassung:A process for preparing sulfuric acid, in which process gases comprising sulfur dioxide are obtained by combustion of liquid sulfur by means of process air introduced from the outside or by dissociation of waste sulfuric acids and the sulfur dioxide in the process gases comprising sulfur dioxide is oxidized to sulfur trioxide and converted into sulfuric acid by the contact process, wherein the process air which is introduced from the outside for combustion of sulfur or the process gases comprising sulfur dioxide which are obtained by dissociation of waste sulfuric acid have their water vapor content reduced by cooling them, is proposed.
