An improved method of drying natural or other gases to extremely low water dewpoints via countercurrent contact with very pure hygroscopic liquid desiccant which is regenerated by heating and reboiling in a distillation stripping column. Preferably, the liquid desiccant is further regenerated in an azeotropic distillation stripping column using a condensable hygroscopic vapor as a stripping and azeotroping medium.</SDOA B>
