sweetening liquid desiccants the improved method still utilizes a reboiler and distillation column to remove the bulk of liquid water absorbed by the liquid desiccant but it employs a liquid or valve seal between the reboiler and a polishing vapor stripping column in which the lean descending liquid desiccant generates equilibrium desiccant water vapor in its vapor space the water laden desiccant vapor rises up an internal conduit of a separation chamber mounted above the stripping column to a condensing coil where the desiccant and water vapors are liquefied and introduced into said upper separation chamber the liquid settles to the bottom of the chamber and is level controlled and gravity fed to a water disposal tank or back into the reboiler as the process warrants the very lean liquid desiccant exits the vapor stripping column for further use as a gas drying desiccant the present method regenerates a hygroscopic liquid desiccant to a low moisture content allowing for the attainment of low water contents of natural or other gases without the utilization of condensable or non condensable stripping vapor which is often vented to atmosphere although this water exhaustive liquid desiccant regeneration system may also be designed to operate either with condensable hygroscopic vapor or non condensable stripping gas in the stripping column as operating process and environmental circumstances warrant besides eliminating costly stripping gas losses or the inefficiencies inherent in the use of a condensable hygroscopic stripping vapor water exhaustive stripping allows for the improved recovery of desiccant absorbed.
