“…Carbon monoxide oxidation in supercritical water was first studied in our laboratory by Helling and (2) where the units are as in eq 1. Holgate et al" also developed a rate expression for the direct-oxidation pathway, which incorporated experimental data from the earlier study10 as well as newer data:…”

“…Water above its critical point ( T c = 647 K, P c = 221 bar) is highly miscible with both organics and oxygen. SCWO technology has been shown to be effective for destroying a large variety of industrial and high-risk wastes. The SCWO process is conducted at temperatures and pressures above the critical point of water and is considered applicable to aqueous streams containing 0−20% organics . As this technology has become commercially available, , interest in process development research has been shifting from feasibility demonstration to the evaluation of process scale-up costs.…”

“…Supercritical water oxidation has been used to successfully treat a wide variety of wastes including organics (Thomason and Modell, 1984), halogenated organics (Swallow et al, 1989), biological and pharmaceutical wastes (Johnston et al, 1988;Hong et al, 1987), and surrogate mixed waste (Bramlette et al, 1990). However, when treating organic compounds containing chlorine, sulfur, phosphorous, and certain nitrogen groups, the products of oxidation include strong acids such as HCl (Swallow et al, 1989). The presence of these acids combined with the high temperatures and oxidizing media of the process create an extremely corrosive environment, resulting in degradation of structural materials.…”
