Patent number: 6848258Abstract: A gas transfer system and method for dissolving at least one gas into a liquid. The system includes a gas transfer vessel also known as a reactor. A liquid inlet feed is connected to the reactor for transferring the liquid into the reactor. A gas inlet is connected to the reactor for feeding the gas into the reactor. An outlet is connected to the reactor for transferring the liquid with at least some of the gas therein away from the reactor. The system also includes a feed pump connected to the inlet feed to pressurize the contents of the inlet feed and the reactor, and a regenerative turbine connected to the feed pump and to the outlet. The various embodiments of the gas transfer system use pressurization in the gas transfer vessel to enhance gas transfer therein, minimize the net energy consumption, and retain highly supersaturated dissolved gas in solution. Some embodiments further help to reduce effervescence loss.Type: GrantFiled: September 29, 2003Date of Patent: February 1, 2005Assignee: Eco-Oxygen Technologies, LLCInventor: Richard E. Speece

Publication number: 20030201554Abstract: A method and apparatus for dissolving a gas into a fluid which may contain at least one other dissolved gas. The apparatus includes an inlet tube for receipt of the fluid from a container containing the fluid. A gas inlet is operably connected to the inlet tube for the introduction of gas into the fluid. The mixture of gas and fluid is introduced into a gas transfer device via the inlet tube. The gas transfer device is positioned below the surface of the fluid in the container so that the gas transfer device is hydrostatically pressurized in order to increase the rate and concentration at which the gas is dissolved into the fluid. The gas and fluid mixture is allowed to flow downward through the gas transfer device such that bubbles of gas are dissolved in the fluid. The fluid having the gas dissolved therein enters an outlet means positioned within the gas transfer device.Type: ApplicationFiled: April 1, 2003Publication date: October 30, 2003Applicant: Eco-Oxygen Technologies, LLC, an Indiana limited liability companyInventor: Richard E.

Patent number: 6474627Abstract: A method and apparatus for dissolving a gas into a fluid which may contain at least one dissolved gas. The apparatus includes a conventional U-tube oxygenator which includes a U-tube member having an inlet for the introduction of the fluid and the gas to be dissolved into the fluid, and an outlet. The fluid is housed in the U-tube member. The apparatus further includes a helix-shaped bubble harvestor located proximate the bottom of the inlet side of the U-tube member. The helix-shaped bubble harvester removes fugitive (undissolved) gas bubbles from the fluid flow and returns them to the bubble swarm located above the helix-shaped bubble harvestor. The resulting fluid, which contains a high concentration of dissolved gas, exits the outlet of the U-tube member.Type: GrantFiled: October 26, 2001Date of Patent: November 5, 2002Assignee: Eco-Oxygen Technologies, LLCInventor: Richard E.
