Abstract
Processes are provided for accomplishing wet oxidation using a reaction zone wherein the gas phase (oxygen) is allowed to pass therethrough at a flow rate independent of the liquid phase (waste water) flow rate so that more oxygen can be supplied to a given volume of waste water than is possible for a conventional reactor of the equivalent size. A high efficiency wet oxidation is provided by which the process technology can be practiced either in a single stage or multistage. The reactor is directed to operate at temperatures ranging from about 350.degree. to 600.degree. F. at pressures ranging from about 800 to 2200 psig and the reactor provides a gas phase/liquid phase separation feature.
