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.
