Abstract
A method and apparatus for increasing the concentration of oxygen in the reaction medium present in the oxidation reactor. A volume of aqueous medium from the oxidation reactor is removed and pressurized and oxygen is added to it. The oxygen-rich volume of aqueous medium is then reintroduced into the oxidation reactor at an increased pressure to ensure adequate mixing with the aqueous medium having a lower content of oxygen.
