Abstract
This invention relates to the low temperature regeneration of liquid desiccants and acid gas absorbing liquid desiccants. Both classes of desiccants can be regenerated to separate water and/or water and acid gases to a satifactory degree under the pressure conditions employed at temperatures substantially below the normal boiling point of the dry desiccant or desiccant-water mixture by countercurrently contacting the desiccant to be regenerated in conventional distillation equipment with the vapors of an easily condensable hydrocarbon or hydrocarbon mixture which is substantially immiscible with the regenerated desiccant at the boiling temperature of the hydrocarbon or hydrocarbon mixture employed as a stripping agent.
