Abstract
A method and apparatus for dissolving a gas into a fluid which may contain at least one dissolved gas. The apparatus includes an inlet through which fluid enters the apparatus. The fluid is then housed in a chamber. The apparatus also includes a feed for the introduction of the gas into the fluid housed in the chamber. The chamber has a first portion having a diverging interior surface and a second portion having a cylindrical surface, which configuration enhances gas absorption. Further, the apparatus includes an acceleration plate which accelerates the flow of fluids and gas bubbles in the chamber. In addition, the apparatus includes a helix-shaped bubble harvestor which removes fugitive (undissolved) gas bubbles from the fluid flow and returns them to the chamber above the harvester to increase the probability that those bubbles will be dissolved in the fluid. Fluid having gas dissolved therein exits the chamber through an aperture through the bottom surface of the chamber into an outlet.
