Abstract
A process for removal of organic impurities from a gas mixture is disclosed for removing most of the impurities from the gas mixture in an economical way. The gas to be purified is subjected to two successive purification stages, in which the impurities still remaining in the gas to be purified after the first purification stage are burned in a second purification stage and the released energy thus is used for operating the first purification stage.
