DESULFURIZATION OF SMOKE

A process for desulfurizing waste gas is described, wherein an SO2 containing waste gas is absorbed in an aqueous solution and the resultant solution containing sulfite is treated electrolytically which is much less expensive than the prior art methods, is simpler to implement and avoids the danger...

Beschreibung
Zusammenfassung:	A process for desulfurizing waste gas is described, wherein an SO2 containing waste gas is absorbed in an aqueous solution and the resultant solution containing sulfite is treated electrolytically which is much less expensive than the prior art methods, is simpler to implement and avoids the danger of producing explosive gases which is possible in prior art methods based on anodic O2 formation and cathodic H2 formation. In this process, electrochemical oxidation of SO32- ions into SO42- ions occurs at the anode as well as a simultaneous formation of H+ ions, thereby producing H2SO4, while avoiding the production of oxygen. Apparatus suitable for carrying out this process is also described.
