The work accomplishments during this project consist of five different studies conducted by three current PhD students in the laboratory. An experimental study of methylphosphonic acid (MPA) oxidation has been completed that includes macroscopic modeling of the overall global rate law for MPA oxidation in supercritical water (SCW) and for the major pathways in MPA oxidation. Additionally, an elementary reaction rate model for supercritical water oxidation (SCWO) of MPA has been developed consisting of rate parameters from the available literature and ab initio calculations. Urea hydrolysis kinetics have been experimentally measured at sub and supercritical water conditions. Additionally, recent studies in the laboratory include a co-oxidation stud of MPA and ethanol kinetics in SCW and a methane SCWO experimental study.

Download Using Supercritical Water Oxidation to Treat Hydrolysate from VX Neutralization Book in PDF, ePub and Kindle
The U.S. Army has asked the National Research Council (NRC) to evaluate whether supercritical water oxidation (SCWO) is an effective and appropriate means of eliminating hazardous or toxic organic constituents in VX hydrolysate for ultimate disposition. The NRC was not asked to conduct an in-depth analysis of the entire integrated VX bulk agent destruction and disposal process for the Newport Chemical Agent Disposal Facility. As the facility design is being finalized (March 1999-April 2000), the NRC will probably be asked to assess all aspects of the facility design, including monitoring, containment, process control, and redundancy, as well as the quantitative risk assessment (QRA). This report outlines the elements of the proposed neutralization/SCWO technology, evaluates the results of ongoing SCWO tests, and makes recommendations concerning aspects of the technology that require further development. The scope of this evaluation did not include evaluations of other potential technologies or management options for the treatment of VX hydrolysate.

Download The Destruction of Hazardous Chemical Waste by Oxidation in Supercritical Water Book in PDF, ePub and Kindle
The chemistry of oxidation in supercritical water is being investigated for development into a practical destruction process for hazardous chemical waste. In principle, a wide variety of waste streams might be treated by this technology, including those that are unsuitable for incineration because of high water content. To establish a basis for extrapolation of kinetic measurements to a variety of compounds, a mechanism is being developed for oxidation in supercritical water on the basis of conventional free-radical reactions, with modifications for high pressures and high concentrations of water. Global rate expressions for oxidation of methane and methanol in supercritical water have been determined. A base mechanism and modifications to the mechanism to account for the roles of hydrogen bonding and water dimer formation have been investigated for CO. On this limited basis, reasonable agreement between model and experimental results has been obtained. Further verification of the model with experimental results will provide insight into the roles of hydrogen bonding and water dimer formation in oxidation in supercritical water. 30 refs., 3 tabs.

Download Destruction of Hazardous Chemicals by Oxidation in Supercritical Water: A Theoretical and Computational Treatment of Mechanisms and Elementary Reactions Book in PDF, ePub and Kindle
The principal objective of this course of study was the development of detailed kinetic mechanisms which described the oxidation of simple compounds in supercritical water at the elementary reaction level. The compounds chosen were hydrogen and carbon monoxide. Kinetic mechanisms were developed from corresponding high-temperature, low-pressure combustion mechanisms available in the literature. The mechanisms were adapted to the high-pressure conditions of the SCWO environment and the resulting modified mechanisms were used to predict the temporal behavior and temperature and pressure dependence of the oxidation of each compound. The model predictions were then compared to hydrogen and carbon monoxide oxidation data obtained from experimental work carried out in parallel to the kinetic modeling effort. (jg).

Download Detoxification and Disposal of Hazardous Organic Chemicals by Processing in Supercritical Water Book in PDF, ePub and Kindle
A new process for the destruction of hazardous waste makes use of supercritical water (SCW) as the medium for a rapid and highly efficient oxidation reaction. Destruction efficiencies of 99.99% and greater have been achieved for a broad spectrum of organic chloride compounds and solvents. This report presents the results of bench scale tests of the SCW system on a variety of compounds which yielded information on destruction efficiency, performance capacity, reaction kinetics, fate of inorganic heteroatoms and system corrosion. Keywords: Supercritical water; Hazardous waste, Destruction; Oxidation, Hazardous materials.
