Abstract

A method of treating gas containing water in order to remove at least part of the water from the gas, including feeding the natural gas to be treated by a first line, with a liquid fraction containing at least an aqueous phase is fed via a second line in the presence of a solvent into a contact zone, so as to bring the gas into direct contact with the liquid fraction over at least a portion of the contact zone. The solvent is a non-hydrocarbon compound other than water, and simultaneously, the gas is cooled in the presence of the solvent in order to condense at least one liquid phase consisting essentially of water in a mixture with the solvent. The non-condensed gaseous phase is separated from the condensed liquid phase, from which the solvent has essentially been removed
