LIQUID DESICCANT VAPOR SEPARATION SYSTEM
A system for extracting water from the atmosphere is disclosed. The system has a vapor absorber vessel, an absorption cycle pump, a flash drum vapor desorber, a vapor condenser, an output conduit, and a heat exchanger. The vessel has an atmospheric air inlet and outlet ports, at least one liquid desiccant inlet port, at least two liquid desiccant outlet ports, and a surface on which the liquid desiccant flows between the at least one liquid desiccant inlet port and the at least two liquid desiccant outlet ports. The pump is adapted to circulate a first portion of the liquid desiccant from a first of the outlet ports to the at least one inlet port. The desorber is adapted to receive a second portion of the liquid desiccant from a second of the outlet ports, after passage through an expansion valve, the desorber incorporates a heat exchanger for supplying heat to liquid desiccant therein. The condenser receives desorbed vapor from the desorber, the condenser incorporates condensation surfaces adapted to be cooled to a temperature of less than 20° C., for enabling the condensing of the desorbed vapor to water. The output conduit collects water condensed in the condenser. The heat exchanger is located such that it receives desorbed heated liquid desiccant from the desorber and transfers part of its sensible heat to vapor-charged liquid desiccant passing from the vessel to the desorber.
