ABSTRACT:
A cleansing liquid is conveyed along a first closed circuit which includes a scrubbing device. Here, the liquid comes into contact with and scrubs an impurity-containing gas so that the impurities in the gas are transferred to the liquid. When the concentration of impurities in the liquid has increased to a sufficient extent, the impurity-laden liquid is admitted into a second closed circuit which communicates with the first circuit. The second circuit includes an evaporator in which the impurities contained in the liquid are caused to evaporate from the latter. The purified liquid is recycled to the first circuit while the evaporated and highly concentrated impurities are admitted into a combustion chamber and burned.
