ABSTRACT:
High efficiency scrubbing of SO.sub.2 from stack gases by contact with a sodium based liquor is achieved by adjusting the pH of the scrubber liquor supplied to be in the range of 7.00 to 8.00; and a source of such liquor in a dual alkali system is disclosed in which a mixture of slaked lime and limestone is reacted with spent liquor in two stages one of which is at pH above 8.00, the other of which is at a pH below about 6.8 and the pH of the resulting regenerated liquor is adjusted to the desired pH range.
