ABSTRACT:
The present invention relates to a process and apparatus for purifying waste gases by scrubbing with an adsorbent suspension. The adsorbent suspension in a concentration from 40 g/l to 200 g/l is here distributed uniformly or almost uniformly in at least one gas-scrubbing device, passed through at least one ordered mass transfer zone and contacted with the gas and then passed into at least one separately arranged reactor, the biologically degradable or convertible impurities are reacted, with the additional use of aerobic bacteria and oxygen, with forced motion and the purified liquid or suspension is recycled, wholly or as part stream, to the gas-scrubbing device, distributed therein and contacted again with the gas which is to be purified.
