Abstract

A method of drying a gas making use of the distillation of a liquid desiccant, the method comprising the introduction of a stream of make-up liquid containing water and of an organic solvent miscible with water, the solvent being a more volatile solvent than water under the conditions of the method and forming no azeotropes with water, in an intermediate zone of an elongated vertical contact and fractional distillation zone.
