Absorption involves one substance taking in or dissolving another substance. The substance to be treated is generally gaseous, while the absorbing medium is generally liquid but can also be solid. Gas scrubbing is a typical application. In this process, undesirable exhaust gas pollutants or by products from combustion, e.g. sulfur oxides, halogens or their acids, as well as chemicals such as ammonia, are removed directly from exhaust gases or exhaust air. This gas scrubbing generally follows the oxidation process and sometimes precedes it.
