Abstract: A multi-stage bubble-column vapor mixture condenser includes at least a first stage and a second stage. Each stage includes a condenser chamber including a carrier-gas inlet and a carrier-gas outlet and contains a condensing bath. Carrier gas bubbles from the carrier-gas inlet up through the condensing bath, overcoming a hydrostatic head of the condensing bath, to a volume of carrier gas above the condensing bath. The carrier-gas outlet is positioned with an opening for carrier-gas extraction, and the first-stage carrier-gas outlet is in fluid communication with the second-stage carrier-gas inlet to facilitate flow of the carrier gas through the condensing bath in the first-stage condenser chamber, into the volume of carrier gas above the first-stage condensing bath, and then through the condensing bath in the second-stage condenser chamber. The first-stage condenser chamber further includes an intermediate-exchange inlet positioned and configured to inject additional carrier gas into the first-stage condenser.

Abstract: A feed liquid flows into a second-stage humidifier chamber to form a second-stage humidifier bath. A first remnant of the feed liquid from the second-stage humidifier chamber then flows into a first-stage humidifier chamber to form a first-stage humidifier bath having a temperature lower than that of the second-stage bath. A second remnant of the feed liquid is then removed from the first-stage humidifier. Meanwhile, a carrier gas is injected into and bubbled through the first-stage humidifier bath, collecting a vaporizable component in vapor form from the first remnant of the feed liquid to partially humidify the carrier gas. The partially humidified carrier gas is then bubbled through the second-stage humidifier bath, where the carrier gas collects more of the vaporizable component in vapor form from the feed liquid to further humidify the carrier gas before the humidified carrier gas is removed from the second-stage humidifier chamber.

Abstract: In a bubble-column vapor mixture condenser, a fluid source supplies a carrier-gas stream including a condensable fluid in vapor phase. The condensable fluid in liquid form is contained as a bath in a chamber in each stage of the condenser, and the carrier gas is bubbled through the bath to condense the condensable fluid into the bath. Energy from condensation is recovered to a coolant in a conduit that passes through the liquid in the stages of the condenser. The bubble-column vapor mixture condenser can be used, e.g., in a humidification-dehumidification system for purifying a liquid, such as water.
