PROCESS AND CONTRIVANCE FOR THE REMOVAL OF WATER FROM NATURAL GAS OR INDUSTRIAL GASES USING PHYSICAL SOLVENTS

摘要

The invention relates to a method for drying a natural gas or an industrial gas that contains acidic gas components, wherein the gas drying is followed by a removal of the acidic gas components from the dried gas. The same physical solvent is used for both of the process steps of gas drying and of acidic gas removal. The gas to be dried is brought into contact with the physical solvent, which absorbs most of the water contained in the gas. The physical solvent, which is then loaded with water, is transferred into a solvent regenerating device in which the solvent is heated. In the solvent regenerating device, the water contained in the solvent is stripped from the solvent in the countercurrent by means of a sub-flow of the acidic gas that is removed from the dried useful gas during the acidic gas absorption, said acidic gas being released again in the acidic gas solvent regenerating device, stripped from the solvent, and discharged from the solvent regenerating device. The invention also relates to an arrangement as the device with which said method can be performed.
