Abstract
An apparatus is provided for drying a gas by gradually releasing and condensing the moisture in various chambers of a column, different pressures and different temperatures thus being present in the chambers of the column. The gas to be dried is first fed into the bottom chamber, where the largest amount of the water contained in the gas is condensed, and the gas is then discharged from the bottom chamber via a nozzle. Subsequently the gas is cooled and fed into at least one more chamber located above the first chamber, where further moisture is condensed before the resulting condensate is fed via a pipe—preferably shaped like a siphon—into the bottom reservoir to prevent the gas from flowing from the chamber below into the chamber above. A process which enables a gas to be dried is also described.
