ABSTRACT:
A method of desulfurizing exhaust gases by a wet lime-gypsum process comprises the steps of neutralizing a suitable amount of liquid containing impurities separating the neutralized material into solid and liquid phases, heating the separated solid phase to dryness while concentrating the separated liquid phase, mixing the concentrated liquid and dried solid phase in such a manner that the resulting mixture exists as a solid mass containing the impurities, thus making it unnecessary to dispose of any waste liquid.
