    Abstract: 1. A process for removing CO2 and/or H2 S from a gas containing CO2 and/or H2 S by washing the gas with an aqueous alkanolamine-containing absorption liquid and subsequently regenerating the latter, wherein the aqueous absorption liquid used contains from 3 to 60% by weight of methyldiethanolamine and from 1 to 50% by weight of monoethanolamine, processes with two absorption stages arranged in series, in which regeneration of the laden absorption liquid is carried out using two flash stages and a stripping zone, to the extent they utilize an absorption liquid containing from 0.05 to 1 mole of monoethanolamine per litre, being excluded.

    Abstract: A process for simultaneously removing water and hydrogen sulfide from gases containing both of these by treating the gases, in an absorption zone under superatmospheric pressure, with polyethylene glycol dialkyl ethers as a solvent, stripping the hydrogen sulfide from the loaded solvent, obtained from the absorption zone, in a desorption zone, removing the water, taken up in the absorption zone, from the solvent and recycling the regenerated solvent to the absorption zone, wherein the solvent additionally contains from 0.01 to 20% by weight, based on the solvent mixture, of an alcohol or ether boiling in the range from 50 DEG to 140 DEG C.
