Status Report: Process Technology Improvements in Supercritical Water Oxidation (C.L.E.A.N. Tech)

This paper will discuss some of the most recent process technology improvements in supercritical water oxidation of wastes, over the last 15 years, and highlight the status of current facilities in operation around the world. Supercritical Water Oxidation Technology established itself about 25 years ago as an emission-free method to destroy toxic wastes, especially aqueous sludges. The technology is very efficient in destroying chlorinated organic toxins such as PCBs and Dioxins that resist destruction in conventional incinerators. As 'green' initiatives have increased, this technology has continually gained momentum because it's efficient and contained, producing pure water, ash, and carbon dioxide by-products.

(Note: A separate session by the same author will focus on the economics of building and running a SCWO facility.)
