ABSTRACT:
The invention relates to separately removing organic and inorganic impurities from exhaust gases so that the recovered materials are relatively pure and re-usable, using adsorption on carbon for selective removal of the organics and absorption in aqueous media for the inorganics. Carbon is first saturated with the same inorganics so that, when contacted with the exhaust gas, it removes only the organics. The residual gas, free of organics, upon absorption gives an inorganic solution of high purity. Steam regeneration of the carbon liberates the volatile organics. Systems are described using the two carbon beds in series, the second of which is undergoing inorganic presaturation while the first is removing the organics.
