Abstract
A process for partial dehydration of a gas by contact with a solvent that can be regenerated by: a) A stage for absorption of H2O by contact of the gas to be treated and regenerated solvent producing a dehydrated gas effluent and a liquid solvent effluent that is charged with H2O and absorbed gas, b) A stage for cooling the solvent charged with H2O at ambient temperature, c) A stage for separation by segregation during which liquid H2O and the solvent are separated at ambient temperature, d) A stage in which the regenerated solvent that is obtained at the end of stage c) is heated, e) A stage in which the regenerated and heated solvent that is obtained at the end of stage d) is recycled to the absorption stage a).
