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: The invention concerns an oxidising method by wet process oxidation or ozonization of a liquid contained in a reactor. The gaseous roof (20) is sucked into the liquid, the part undissolved in the liquid is recuperated in the gaseous roof. The stirring means (2) generates a liquid flux immediately proximate to the end of the conduit (3) emerging into the liquid and generates a gas/liquid dispersion in the zone (15), wherein the liquid reacts with the gas, then transports and ejects said dispersion at its periphery, such that the gas is dissolved in the liquid in the zone (16) extending from the stirring means (2) to the surface of the liquid. The method is more particularly suitable for all oxidising processes using large amounts of oxygen or ozone. It is in particular used for oxidising paper-mill liquors.

Abstract: An apparatus (10) for dissolving a gas into a fluid which may contain at least one dissolved gas. The apparatus (10) includes a first vertically oriented tube (2) defining a first inner space (32) and a second vertically oriented tube (12). The space between the first and second tubes is referred to as the second inner space (40). The gas is introduced through an inlet (18) into the second inner space (40). The apparatus (10) includes an acceleration device (20) for accelerating the flow of fluid through the second inner space (40). The apparatus includes a helix-shaped bubble harvester (22) which removes fugitive (undissolved) bubbles from the fluid flow and returns them to the second inner space (40) to increase the probability that those bubbles will be dissolved into the fluid.

Abstract: In order to dissolve a gas such as oxygen in a liquid, typically aqueous, a stream of liquid is taken from tank 2 by a pump 10 and pressurised thereby. Oxygen is introduced into the stream via a conduit 18 upstream of a venturi 20. Turbulence created as the stream passes through the venturi 20 helps to disperse the oxygen as fine bubbles in the stream. The dispersion is then conducted to a sparge pipe 14 and introduced into the main volume 4 of liquid in the tank 2. The bubbles are thereby sheared into very small bubbles that readily dissolve in or are consumed by the volume 4 of liquid. Some of the gas in the dispersion is separated therefrom at a relatively downstream position and drawn along a pipe 26 back into the stream at a relatively upstream position by the action of the stream passing through the venturi 20. A valve 28 is operable to regulate the rate at which gas is so recycled.

Abstract: In order to dissolve a gas such as oxygen in a liquid, typically aqueous, a steam of liquid is taken from tank 2 by a pump 20 and pressurised thereby. Oxygen is introduced into the stream via a conduit 18 upstream of a venturi 10. The resulting mixture of oxygen bubbles and liquid is accelerated from a sub-sonic to a super-sonic velocity as it flows through the venturi 20. The resultant shockwave is effective to reduce the size of the bubbles. The stream of liquid carrying oxygen bubbles dispersed therein is then transported at sub-sonic velocity along the conduit 12 to a sparge pipe 14 through which it is introduced into the main volume 4 of liquid into the tank 2. As the liquid passes through the orifices of the sparge pipe 14 so it is again accelerated to a super-sonic velocity and another shockwave is created thereby causing the bubbles to reduce in size such that they readily dissolve in or are consumed by the main volume of liquid.
