Improved oxidation method and reactor

摘要

Disclosed herein are methods for increasing the concentration of oxygen in a reaction medium present in an 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 in the oxidation reactor having a lower content of oxygen.
