ABSTRACT:
A process is described for the removal of oxides of sulfur, dust and mist from a combustion waste gas such as the waste gas evolved from a glass melting furnace in which the waste gas is contacted with an absorbing solution containing an alkaline absorbent such as NaOH, Na.sub.2 CO.sub.3 or Na.sub.2 SO.sub.3, whereby the oxides of sulfur are absorbed and the temperature of the waste gas is decreased and the humidity of the waste gas in increased. The treated waste gas is then passed through a glass fiber filter which is maintained under moist conditions in order to efficiently remove dust and mist particles from the waste gas. Crystalline sodium sulfate hydrate is recovered from the absorbing solution contacted with the waste gas.
