Abstract
A method for efficiently providing supplemental oxygen to a reaction mixture which is oxidized by or otherwise uses air, wherein the reaction mixture is agitated to create one or more stationary vortices, oxygen is injected into the reactor vessel at a stationary vortex, and air bubbles are circulated within the reaction mixture in the reactor vessel and outside the stationary vortex or vortices into which the oxygen is injected.
Claims10
A method for providing supplemental oxygen to a reaction mixture comprising:
- (A) providing air into a reactor vessel containing a reaction mixture, and passing the air in the form of air bubbles within the reaction mixture;
- (B) agitating the reaction mixture to create a stationary vortex;
- (C) providing oxygen in the form of oxygen bubbles directly into the stationary vortex;
- and
- (D) passing oxygen out from the oxygen bubbles and dissolving oxygen into the reaction mixture.
