20130015051 | Separation of a Vaporizable Component Under Reduced Pressure - The productivity of a combined heat and mass transfer device is improved by directing a flow of a carrier-gas mixture through a fluid flow path in a combined heat and mass transfer device operating at a pressure below atmospheric pressure. Heat and mass are transferred from or to the carrier-gas mixture by a direct or indirect interaction with a liquid composition that includes a vaporizable component (e.g., water) in a liquid state to substantially change the content of the vaporizable component in the carrier-gas mixture via evaporation of the vaporizable component from the liquid composition or via condensation of the vaporizable component from the carrier-gas mixture, producing a flow of carrier-gas mixture having a concentration of the vaporizable component that differs from the concentration of the vaporizable component in the carrier-gas mixture before the heat and mass transfer process. | 01-17-2013 |
20130074694 | Bubble-Column Vapor Mixture Condenser - 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 fluid into the bath. The bubble-column vapor mixture condenser can be used, e.g., in a humidification-dehumidification system for purifying a liquid, such as water. | 03-28-2013 |
20130075940 | Bubble-Column Vapor Mixture Condenser - 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 fluid into the bath. Energy from condensation is recovered to a liquid composition 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. | 03-28-2013 |
20140367871 | Multi-Stage Bubble Column Humidifier - 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. | 12-18-2014 |
20150260418 | Humidification-Dehumidification System with a Bubble-Column Vapor Mixture Condenser and Intermediate Gas Extraction - 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. | 09-17-2015 |
20150290557 | Multi-Stage Bubble-Column Vapor Mixture Condenser - A multi-stage bubble-column vapor mixture condenser comprises at least a first stage and a second stage. Each stage includes a carrier-gas inlet and a carrier-gas outlet, as well as a condenser chamber containing a condensing bath in fluid communication with the carrier-gas inlet and the carrier-gas outlet. The carrier-gas inlet is positioned to bubble carrier gas from the carrier-gas inlet up through the condensing bath, overcoming a hydrostatic head of the condensing bath. The carrier-gas outlet is positioned with an opening for carrier-gas extraction above the condensing bath, wherein the first-stage carrier-gas outlet is in fluid communication with the carrier-gas inlet of the second stage to facilitate flow of the carrier gas through the condensing bath in the condenser chamber of the first stage and then through the condensing bath in the condenser chamber of the second stage. | 10-15-2015 |

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. | 11-12-2015 |
