Abstract:
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. The method of the present invention utilizes the system of the present invention and operates the feed pump and regenerative turbine to accomplish these advantages.

Abstract:
System and apparatus to accelerate solution of gas into liquid. The system includes an aspirating injector to bring the gas into the pressurized system, a collider, a reactor, and an optional gas/liquid separator. The collider and reactor provide for prompt renewal of the interface in the bubble with the liquid as the consequence of abrupt changes of direction of flow.
Abstract:
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.
Abstract:
The present invention relates to a process of oxidation, of the wet oxidation or ozonization type, of a liquid contained in a reactor. The gas of the gas headspace is aspirated into the liquid, and the portion which is not dissolved in the liquid is recovered in the gas headspace. The agitation means creates a flow of liquid immediately adjacent to the end of the duct opening into the liquid, and generates a gas/liquid dispersion in the zone, within which the liquid reacts with the gas, then conveys and ejects the said dispersion at its periphery, such that the gas is dissolved in the liquid in the zone extending from the agitation means to the surface of the liquid. The said process is particularly suitable for oxidations which make use of considerable quantities of oxygen or of ozone. It is particularly applied for the oxidation of papermaking liquors.
Abstract:
An improved apparatus for the introduction of a gas into a liquid comprising a mixing device formed by a first generally convergent section and a second generally divergent section, said first section having a narrow outlet end of smaller diameter than an inlet end of said second section and extending thereinto so as to form an annular gap therebetween, and supply means for supplying said gas to said annular gap so as to facilitate the mixing of said gas with any liquid passing therethrough. The mixing device is preferably positioned at or near the surface of the liquid so as to avoid problems associated with hydrostatic head. The apparatus is advantageous in the treatment of a liquid with oxygen which is preferably generated by a Pressure Swing Adsorption device.
