Abstract
Method of treatment of a hot exhaust gas stream containing acid forming pollutants to produce a scrubbed exhaust and useful or benign by-products. The gas stream is first passed through a heat exchanger and then reacted with an aqueous, alkaline scrubbing solution. After the reaction the solution, now containing dissolved salts with a precipitate of any insolubles, is passed through the heat exchanger wherein it is heated by the gas stream to remove water therefrom, thereby crystallizing the dissolved salts, and wherein it serves to cool and dehumidify the gas stream in a manner to remove heat and collect water therefrom prior to its reacting with the scrubbing solution. Any remaining insolubles are non-toxic or useful, e.g. as cement kiln feed.
