    Abstract: The process relates to the production of a liquid absorbate from a liquid F and a readily soluble gaseous substance A. In this process, beginning with the liquid F and a gaseous mixture of A and a gaseous substance B sparingly soluble in F, this mixture, in a first reaction vessel, is brought into intimate contact with the liquid F, the undissolved portions of gaseous substance B are conducted away and the resulting liquid phase of F and A and small portions of B is expanded in a second reaction vessel. The thus released portions of B (and possibly A) are withdrawn as a gas phase. A liquid absorbate is obtained composed of F and A, which is essentially free of B. The gaseous mixture used is at a pressure of above 1 bar and the resulting liquid phase composed of F, A and small portions of B is expanded in an evacuated vessel. The vacuum is generated by a gas jet pump which is driven by the pressurised gaseous mixture of A and B. The gaseous mixture exiting the pump is brought into intimate contact with the liquid F. Alternatively, the vacuum is generated by a liquid jet pump which is driven by the pressurised liquid F. In this case, the liquid which exits the pump is brought into intimate contact with the gaseous mixture of B and, possibly, A.
