Abstract
Acid constituents, eg. H.sub.2 S and CO.sub.2 or their mixtures, are removed from industrial gases or natural gases by means of a washing agent which contains the methyl isopropyl ethers of polyethylene glycols. The washing can be carried out with simultaneous drying of the gas, especially in the case of natural gases, since the anhydrous ethers are able to absorb water.
