Abstract

The method of this invention is particularly, although not exclusively, adapted for effecting accelerated oxidation reactions in a downhole or deep well wet oxidation apparatus, including the processing of aqueous organic waste, such as municipal sludge. It includes injecting a multiple-phase composition which contains an oxygen or an oxygen-rich gas which is fully saturated with water vapor and which also contains water in the liquid phase into a wet oxidation reaction apparatus which contains an aqueous stream of combustible waste, preferably at the temperature and pressure of the waste stream at the point of injection. This reduces the likelihood of hazardous spontaneous combustion which may otherwise occur if dry spots are allowed to form in the reaction apparatus. The volume of water in the composition should be equal to at least twice the volume of water necessary to saturate the gas with water vapor to maintain at least 50 percent of the water in the liquid phase.
