چکیده

The destruction of toxic organic wastewaters from munitions demilitarization and complex industrial chemical clearly becomes an overwhelming problem if left to conventional treatment processes. Two options, incineration and supercritical water oxidation (SCWO), exist for the complete destruction of toxic organic wastewaters. Incinerator has associated problems such as very high cost and public resentment; on the other hand, SCWO has proved to be a very promising method for the treatment of many different wastewaters with extremely efficient organic waste destruction 99.99% with none of the emissions associated with incineration. In this review, the concepts of SCWO, result and present perspectives of application, and industrial status of SCWO are critically examined and discussed.

Experimental Determination of Hydroxyl Radical Reactivity in Supercritical Water Using Pulse Radiolysis

Complete mineralization of hazardous organic compounds to innocuous products can be achieved using supercritical water oxidation (SCWO). At typical SCWO process conditions (500 – 650 °C), free radical chemistry has been shown to be the dominant reaction path. Detailed Chemical Kinetic Mechanisms (DCKM), consisting of elementary free-radical reactions, have been used to model the oxidation of a ...
