Abstract

An apparatus and method for increasing gas absorption in a liquid includes, in a first embodiment, gas injection airfoils at an inlet of an extended vertical tube and a pump at an outlet of the tube for drawing the liquid at a rate greater than the rise rate of the gas bubbles. An outlet of the pump preferrably includes a plurality of outlet nozzles. A second embodiment for use with a liquid or slurry includes a venturi gas inlet in place of the airfoils.
