Abstract

The invention concerns a method for elimination of sulphur from the noxious gases occurring in a sulphate cellulose factory. The sulphur dioxide obtained by burning of the noxious gases is treated in a smoke gas scrubber with a solution containing NaOH and the resulting solution containing sodium bisulphite is treated with the residual calcium oxide obtained from the sludge burning, so that the sulphur can be recycled as a calcium sulphite and calcium sulphate precipitation.
