Abstract: Device for drying a gas, consisting of a dryer (2) of the type using a pressure vessel (3) with a drying zone (4) and regeneration zone (5), with an adsorption and/or absorption medium (6) which is brought alternatively through the drying zone (4) and the regeneration zone (5); a main canalization (7) allowing that the gas to be dried is led through the drying zone (4) of the dryer (2); an auxiliary canalization (8) allowing that part of the gas to be dried is led through the regeneration zone (5) of the dryer (2) and taked up moisture herein; a cooler (9, 47, 53, 62, 66) providing in the cooling of the gas from the auxiliary canalization (8), whereby liquid excretion takes place; and a blending device (10) for adding the gas from the auxiliary canalization (8) back to the gas in the main canalization (7), characterized in that the blending device (10) is integrated in the dryer (2).
