METHOD OF DEHYDRATING GAS CONTAINING CO Russian patent published in 2014 - IPC F25J3/02 F25J3/08 

FIELD: chemistry.

SUBSTANCE: method of dehydrating a gas containing CO₂ is based on preparing a two-phase mixture with expansion thereof and separating the liquid phase from the mixture in a separator. Raw gas is cooled by adding liquid CO₂ with water dissolved therein; the obtained mixture is separated into a gas phase and a liquid phase containing water; the gas phase is expanded to obtain a liquid containing liquid CO₂ and water; the liquid is partially or completely fed for mixing with raw gas, wherein expansion is carried out to temperature below the hydrate formation point.

EFFECT: higher degree of dehydration of the gas.
