Abstract

La presente invenzione concerne un procedimento per la desolforazione di gas di scarico umidi contenenti SO2, in particolare quelli dalla desolforazione di mosto, e un dispositivo per l'attuazione del procedimento. Anzitutto vengono condensate porzioni condensabili del gas di scarico, quindi il gas di scarico viene immesso in soluzione acquosa di perossido d'idrogeno; l'interruzione del punto finale avviene comandata elettronicamente. Mentre la purificazione di gas di scarico finora era connessa con la creazione di un prodotto di scarto secondo la presente invenzione viene ricavato acido solforico puro adatto per la vendita.The present invention relates to a process for the desulphurization of wet exhaust gases containing SO2, in particular those from the desulphurization of must, and a device for carrying out the process. First, condensable portions of the exhaust gas are condensed, then the exhaust gas is introduced into an aqueous solution of hydrogen peroxide; the end point is interrupted electronically controlled. While the purification of exhaust gases has hitherto been connected with the creation of a waste product according to the present invention, pure sulfuric acid suitable for sale is obtained.
