  • Patent number: 10688409
    Abstract: A counter-flow simultaneous heat and mass exchange device is operated by directing flows of two fluids into a heat and mass exchange device at initial mass flow rates where ideal changes in total enthalpy rates of the two fluids are unequal. At least one of the following state variables in the fluids is measured: temperature, pressure and concentration, which together define the thermodynamic state of the two fluid streams at the points of entry to and exit from the device. The flow rates of the fluids at the points of entry and/or exit to/from the device are measured; and the mass flow rate of at least one of the two fluids is changed such that the ideal change in total enthalpy rates of the two fluids through the device are brought closer to being equal.

  • Patent number: 10456757
    Abstract: A method and apparatus for carbonating a liquid in a pressurizable vessel, including first connecting a vessel with a carbon dioxide tank, wherein said vessel contains a liquid. A vessel can then be pressurized with carbon dioxide to a desired first pressure. A pump is activated to circulate the liquid through a hose out of the vessel to a fitting assembly and out of the fitting assembly back into the vessel. While the liquid is flowing through the fitting assembly carbon dioxide is introduced to the liquid at a second pressure level, wherein the second pressure is greater than said first pressure. After a pre-determined period of time the pump is deactivated and the carbon dioxide can cease to be introduced to the liquid flowing through the fitting assembly.

  • Patent number: 10053373
    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.

  • Patent number: 9327207
    Abstract: The spherical desalination device includes a hollow spherical transparent shell serving as a distillation chamber or still. Water initially flows through an underground system for geothermal heating, then flows into the hollow shell. The water flows from the upper portion of the shell, filling a series of concentric circular trays arranged in a conical stack within the shell. Water cascades from the smallest diameter uppermost tray to the largest lowermost tray, in sequence. Sunlight focused on the transparent shell causes the water to evaporate, and condensation collects upon the interior surface of the shell. A resilient seal extends about the lower rim of the largest and lowest evaporator tray, and is located at the equator of the hollow shell. The shell is rotated by an external motor, thereby drawing the internal surface of the shell across the seal to remove collected condensation from the internal surface of the shell.

  • Patent number: 8771407
    Abstract: Various apparatus provide for spraying high velocity droplets of liquid into a low velocity gas stream. Finely atomized droplets may quickly transfer their momentum to the gas, resulting in deceleration of the spray and acceleration of the gas. A high velocity spray of atomized liquid may transfer a substantial fraction of its kinetic energy to the gas before contacting a surface, in some aspects, suspended particles in the gas phase may be removed by high velocity liquid droplets passing through the gas. Certain aspects provide for controlling a gas flow by controlling the relative amounts of upstream and downstream momenta transferred to the gas by one or more liquid sprays.

  • Patent number: 8647477
    Abstract: Water can be separated from a liquid composition (e.g., salt water) by directing a carrier gas flow through an evaporator and directly contacting the carrier gas flow with the liquid composition in the evaporator to humidify the carrier gas with water evaporated from the liquid composition, producing a humidified gas flow, which is then compressed by injecting a fluid that includes steam and/or an organic compound at an elevated pressure at least five times greater than the pressure in the evaporator and at a temperature at least as high as a saturation temperature of the steam/organic compound at the elevated pressure of the fluid. After being compressed, the humidified gas flow is directed through at least one condenser where water is condensed from the compressed humidified gas flow and collected; and the dehumidified gas flow is re-circulated back through the evaporator for reuse as the carrier gas.

  • Patent number: 8608841
    Abstract: In a process, a portion of a liquid mixture flow is vaporized to produce a vapor and a depleted flow of liquid. The vapor is introduced to a brine which is adapted to exothermically absorb one or more components therefrom, and heat is withdrawn, to produce at least a flow of heat and a flow of brine which is enriched in the one or more components. The heat previously withdrawn is transferred, to drive the vaporization. This transfer can be associated with the change of a working fluid from a gaseous into a liquid state. In this case, the heat withdrawal involves the change of the working fluid from the liquid to the gaseous state. In the liquid state, the working fluid flows only by one or more of gravity, convection and wicking. In the gaseous state, the working fluid flows only by one or more of diffusion and convection.

  • Patent number: 8109489
    Abstract: A method for contacting gases and liquid droplets for mass and/or heat transfer and a spray tower are disclosed, in which liquid is injected at a number of levels in counterflow to the gas, the gas being fed through at least two inlet openings in the shell of the spray tower. In this case, in order to reduce the differences in the contact duration, the flow direction of the gas at the inlet openings points into the internal region of the spray tower, which has a diameter of greater than or equal to 12 m, in particular greater than 20 m, such that the flow directions of the at least two gas streams intersect on their extension inside the spray tower, in particular at the center of the spray tower at up to half the spray tower radius downstream of the center of the spray tower.

  • Patent number: 8105419
    Abstract: The invention relates to a gas liquid contactor and effluent cleaning system and method and more particularly to an array of nozzles configured to produce uniformly spaced flat liquid jets shaped to minimize disruption from a gas. An embodiment of the invention is directed towards a gas liquid contactor module including a liquid inlet and outlet and a gas inlet and outlet. An array of nozzles is in communication with the liquid inlet and the gas inlet. The array of nozzles is configured to produce uniformly spaced flat liquid jets shaped to minimize disruption from a gas flow and maximize gas flow and liquid flow interactions while rapidly replenishing the liquid.

    Abstract: The invention is intended to produce high-pressure light fuel gas with good combustibility by contacting and reacting high-temperature, high-pressure water and heavy oil with each other in a contact-reaction unit to extract light oil components from the heavy oil and to remove metals. The high-temperature, high-pressure water and the heavy oil are introduced to the contact-reaction unit for contact and reaction with each other therein. Heavy oil components not dissolved in the high-temperature, high-pressure water are separated by precipitation from hydrocarbon gases and light oil components which are dissolved in the high-temperature, high-pressure water. The separated heavy oil components are burnt or incinerated without any further modification.
