ABSTRACT:
An air-vapor mixture, derived from a vaporous, volatile liquid, has vapors stripped and recovered therefrom, in accordance with the method and apparatus, by first stripping a multi-component vaporous, volatile liquid of at least some of its more volatile constituents and then contacting the air-vapor mixture with a stream of the stripped liquid. Leaning or stripping of the contacting liquid provides an unburdening of cooling means which, selectively, are subsequently deployed to effect vapor absorption condensation. Thus the method and apparatus offer economies in cooling equipment and overall greater efficiency in the liquid absorption. In one embodiment, a jet inductor is used to spray volatitle liquid into the mixture to partially strip the liquid of its more volatile fractions. An embodiment of a sub-combination apparatus comprises means for stripping a vaporous, volatile liquid of vapor, and either storing the vapor-stripped liquid for subsequent use, or continuously using liquid thus vapor-stripped, in vapor stripping and recovery apparatus. The sub-combination apparatus obviates the use of a jet inductor or like devices toward vapor-stripping the volatile liquid as an optional practice of the invention.
