Abstract
By separating a noxious-component-containing flue gas into two separate streams, subjecting one of these streams to dry purification and the other to wet purification, and recombining the resulting purified streams, purified flue gas is obtained at a temperature greater than the dew point of remaining corrosive constituents. This makes it possible to disseminate the recombined product through pipes and chimneys without a deleterious effect thereon. The beneficial results are obtained without having to heat the recombined gas stream even though the wet-purification process yields purified gas at a temperature far below that which is desired. Both the dry- and the wet-purification processes are significantly enhanced by incorporating piperazine in treating materials. Sorption agents used in the dry purification are reused in the wet purification, enhancing the efficiency of the disclosed system.
