A method of regenerating liquid desiccant used in the dehydration or sweetening of gases. A first step involves boiling wet liquid desiccant containing water t o create lean liquid desiccant. A second step involves introducing the lean liquid desicca nt via a liquid seal pot into a water exhausting stripping column. The hot lean liquid desiccant cascades down the stripping column and evolving equilibrium vapors rise up the stripping column. A third step involves directing the rising equilibrium vapor into a condense r in which the vapor undergoes cooling with a resulting phase change back to liquid. The phase change from vapor to liquid reduces pressure in the condenser, which draws more evolving vapor from the lean liquid desiccant cascading down the stripping column upwards into the condenser, thereby further reducing the water content of the lean liquid desiccant to create a very lean liquid desiccant.
