  • Patent number: 10654732
    Abstract: Equipment for massive dissolution of gases in liquids via the formation of thin liquid films and the exchange of gases with said films. The equipment provides movement of liquids over great distances via the upward movement of bubbles therein. The equipment can alter the direction of the flow of water, said aspect being useful for the recovery of liquid bodies. In addition to providing a high rate of dissolution of gases in liquids, the equipment is very energy-efficient and has a very large volumetric capacity, thereby being useful for the preservation and/or recovery of liquid bodies, being able, in certain applications, to operate in an energy-autonomous manner. The equipment can be used in situations where energy-efficient dissolution of gases in liquids is desired, such as the preservation and/or recovery of liquid bodies; processes for preserving and/or improving the productivity of aquaculture systems; wastewater treatment systems; and the fixation of gases.

    Abstract: A fermenter can have at least one hollow fluid conduit disposed at least partially within a vessel. An external circumference of the hollow fluid conduit and an interior circumference of the vessel can define a downward flow path through which a multi-phase mixture including a liquid media and compressed gas substrate bubbles flows. An interior circumference of the hollow fluid conduit can defined an upward flow path which is in fluid communication with the downward flow path. The multi-phase liquid can flow through the upward flow path and exit the fermenter. Cooling may be provided in the hollow fluid conduit or the vessel. One or more backpressor generators can be used to maintain a backpressure on the fermenter. One or more fluid movers can be used to variously create an induced and/or forced flow in the downward and upward flow paths.

  • Patent number: 9732768
    Abstract: An intermittent fluid pump is disclosed wherein a gas is introduced into a fluid storage housing containing liquid. The gas is released intermittently from a fluid transfer housing via a fluid transfer passage into a vertically oriented fluid conveyance conduit thereby creating a density differential along with an ascending lift that sucks liquid into a liquid suction conduit wherein the liquid discharges into the fluid conveyance conduit. The ascending gas and liquid are discharged from the fluid conveyance conduit, allowing liquid to be introduced into both the storage and transfer housings thereby temporarily interrupting any further transfer of gas into the fluid conveyance conduit such that an intermittent cycling of fluid is established.

A larger diameter low-pressure pipe or tube is placed concentrically about the high-pressure pipe. Regulated low-pressure gas flows down through the outer low-pressure pipe to a dispensing nozzle below the diffuser plate, whereupon the gas flows upward and is broken up by the perforations in the diffuser plate to form smaller aeration bubbles.

  • Publication number: 20130069253
    Abstract: Apparatus and process for dissolving gas in a liquid. The process comprises: tangentially introducing a liquid into a chamber having an inner wall with sufficient volume and pressure to develop a vortex in the flowing liquid; orthogonally introducing gas into the flowing liquid through means located at the chamber inner wall for developing gas bubbles within the liquid. The apparatus comprises: a cylindrical chamber having a cylindrical inner wall, the chamber being oriented in any direction enclosed at both ends and with an entry port to introduce liquid to develop a spiral flow of liquid along the chamber inner wall toward the output end, a porous wall to permit the introduction of gas orthogonally into the stream to develop gas bubbles within the stream, and an exit port to discharge the mixture of gas bubbles and liquid.

  • Patent number: 8235360
    Abstract: A fluid jet for injecting fluids in the liquid of a tub through a throughbore in a wall of the tub comprises a gas injector with a hollow body having a gas inlet receiving a gas flow from a pressurized gas source. A gas outlet produces a flux of gas with the gas flow. A liquid injector comprises a hollow body with a liquid inlet connected to a pressurized liquid source to receive a liquid flow therefrom. A liquid outlet produces a flux of liquid with the liquid flow, the gas injector being received in the hollow body of the liquid injector, for the gas outlet and the liquid outlet to form a common jet outlet. The liquid injector is secured to the wall of the tub opposite the throughbore such that fluids exiting the common jet outlet are directed concurrently through the throughbore into the liquid of the tub.
