Abstract
A humidification-dehumidification system comprises a source of liquid; a humidifier including carrier-gas and liquid inlets and outlets and a chamber in which the liquid can contact a carrier gas containing a condensable fluid in vapor phase that is introduced from the carrier-gas inlet in a counterflow arrangement and in which a portion of the liquid can vaporize into the carrier gas; a bubble-column vapor mixture condenser including at least first and second stages, each stage including a carrier-gas inlet and outlet and a chamber configured to contain a liquid bath in fluid communication with the carrier-gas inlet and the carrier-gas outlet; a conduit passing from the source of the liquid through the chamber of each stage of the bubble-column condenser; and an intermediate exchange conduit coupled with (a) the bubble-column vapor mixture condenser and (b) the humidifier chamber at intermediate stages of each for transfer of the carrier gas therebetween.
