FIELD: oil-and-gas industry.
SUBSTANCE: invention relates to a method of drying of natural gas or industrial gas containing acid gaseous components. Gas is dried to remove acid gaseous components therefrom. The same physical solvent is used at both process steps. Gas to be dried is brought in contact with a physical solvent to absorb the major portion of water contained therein. The physical solvent being enriched with water is fed to the solvent recover unit wherein the said solvent is heated. Water contained in the solvent is separated in a countercurrent at the solvent recovery unit with the help of the flow of acid gas extracted from the dried useful gas during absorption of the acid gas. Note here that the acid gas is, again, released at the said recovery unit and separated from the solvent and released from the said unit for the solvent recovery. The invention relates also to a plant for the implementation of the described process.
EFFECT: invention provides efficient gas drying.
