摘要：The invention concerns a method for dehydrating a gas contained in water using a hydrophilic liquid dessicant, with regeneration of said liquid dessicant, characterised in that it comprises: (a) a step for absorbing water by contact between said wet gas and a regenerated liquid dessicant derived from step (c), producing a dry gaseous effluent and a liquid dessicant flux loaded with absorbed water and gas; (b) a step for regenerating said water-loaded liquid dessicant in a regeneration zone comprising a re-boiling zone and a distillation zone, the loaded liquid dessicant being sent in said distillation zone, wherefrom comes out, at the top, vapour containing water and from the base in the re-boiling zone, the liquid dessicant still containing water; and (c) a step wherein said liquid dessicant derived from the re-boiling zone of step (b) and still containing water is sent to an absorption zone, wherein the water and the vapour generated by said dessicant is absorbed by a fraction of regenerated or non-regenerated dessicant, taken at one point of the process, and sending said dessicant which has absorbed the water of said vapour towards the re-boiling zone of step (b) and sending the regenerated dessicant to the absorption zone of step (a).
