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.
