PROCEDE ET DISPOSITIF DE TRAITEMENT D'UN GAZ CONTENANT DE L'EAU TEL QU'UN GAZ NATUREL

摘要

A gas containing at least water is treated to at least partially remove water from the gas by (a) directly contacting the gas with a liquid fraction containing at least one aqueous phase in the presence of a solvent over all or part of the contact area, said solvent being a non-hydrocarbon compound other than water, and, at the same time, at least partially cooling said gas in the presence of said solvent to cause condensation of at least one liquid phase essentially consisting of solvent and water; and (b) separating the uncondensed gas phase from the condensed liquid phase from which the solvent has been at least partially removed.
