Supercritical water oxidation of chemical agents, and solid propellants

A Model Incorporating Ion Dissociation, Solute Concentration, and Solution Density Effects To Describe the Thermodynamics of Aqueous Sodium Chloride Solutions in the Critical Region of Water

“…There has been increasing interest in recent years in the use of supercritical water oxidation (SCWO) to achieve high destruction efficiencies for a wide variety of hazardous chemical wastes − including munitions, polychlorinated biphenyls, aqueous organics, − sewage, and sludges. , The SCWO technology involves the oxidation of the organic components with oxygen or other oxidizing agents in a water medium at temperature ( T ) and pressure ( P ) values above the critical T ( T c ; 374 °C) and critical P ( P c ; 22.1 MPa) values of water. In practice, the oxidation is initiated at about 400 °C and 25 MPa .…”
