CLAIMS

1. A process for conditioning moist gas, c h a r a c t e r i z e d i n that the gas step-by-step is contacted with a successively more concentrated absorption liquid consisting of a solution of one or more non-volatile components in the substance condensing during the absorption, which is carried out isothermally or almost isothermally on cooled surfaces, and that the diluted absorption liquid is concentrated by evaporation and recycled to the absorption device.
2. A process according to claim 1, c h a r a c t e r i z e d i n that the absorption is carried out step-by-step counter-currently, and that the diluted absorption liquid is concentrated by multi-stage evaporation.
3. A process according to claim 1, c a r a c t e r i z e d i n that the diluted absorption liquid obtained in each absorption stage is concentrated in a corresponding stage of a multi-stage evaporator having as many stages as the absorption device.
4. A process according to any of the claims 1-3, c h a r a c t e r i z e d i n that the gas is air, that the absorption liquid is an aqueous solution of one or more salts, and that the resulting air having a low humidity is re-moistened to the desired humidity by the injection of water, whereby the air simultaneously is cooled to the desired temperature by the evaporation of water.
