“…Hydrothermal chemical reactions such as wet-air oxidation and supercritical water oxidation occur in a highly corrosive environment inside a pressure vessel. Average corrosion rates from 23 to 80 mils per year in conventional reaction vessels have been reported by Rice et al (1994) and Latanision and Shaw (1993). The actual observed corrosion is often uneven, and pitting is sometimes seen.…”

SummaryThe main purpose of this work was to demonstrate the Dual Shell Pressure Balanced Vessel (DSPBV) as a safe and economical reactor for the hydrothermal water oxidation of hazardous wastes. Experimental tests proved that the pressure balancing piston and the leak detection concept designed for this project will work.The DSPBV was sized to process 10 gaVhr of hazardous waste at up to 399°C (750°F) and 5000 psia (34.5 m a ) with a residence time of 10 min. The first prototype reactor is a certified ASME pressure vessel. It was purchased by Innotek Corporation (licensee) and shipped to Pacific Northwest Laboratory (PNL) for testing. Supporting equipment and instnunentation were, to a large extent, transported here from Battelle Columbus Division. A special air feed system and liquid pump were purchased to complete the package. The entire integrated demonstration system was assembled at PNL.During the activities conducted for this report, the leak detector design was tested on bench top equipment. Response to low levels of water in oil was considered adequate to ensure safety of the pressure vessel.Shakedown tests with water only were completed to prove the system could operate at 35OOC at pressures up to 3300 psia. Two demonstration tests with industrial waste streams were conducted, which showed that the DSPBV could be used for hydrothermal oxidation. In the first test with a metal plating waste, chemical oxygen demand, total organic carbon, and cyanide concentrations were reduced over 90%. In the second test with a munitions .waste, the organics were reduced over 90% using H,O, as the oxidant.

Staff exchanges are intended to facilitate communication and collaboration among scientists and engineers at Department of Energy (DOE) laboratories, in U.S. industry, and academia. Funding support for exchanges is provided by the DOE, Office of Energy Research, Laboratory Technology Transfer Program. The exchanges offer the opportunity for the laboratories to transfer technology and expertise to industry, gain a perspective on industry's problems, and develop the basis for further cooperative efforts through Cooperative Research and Development Agreements (CRADAs) or other mechanisms.

Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing this collection of information. REPORT TYPE AND DATES COVEREDQuarterly report, Jan. 1-Mar, 31, 1995 TITLE AND SUBTITLE Kinetics of Supercritical Water Oxidation FUNDING NUMBERSN/A AUTHOR(S)Steven F. Rice This project consists of experiments and theoretical modeling designed to improve our understanding of the detailed chemical kinetics of supercritical water oxidation (SCWO) processes. The objective of the three year project is to develop working models that accurately predict the oxidation rates and mechanisms for a variety of key organic species over the range of temperatures and pressures important for industrial applications. Our examination of reaction kinetics in supercritical water undertakes in situ measurements of reactants, intermediates, and products using optical spectroscopic techniques, primarily Raman spectroscopy. Our focus is to measure the primary oxidation steps that occur in the oxidation of methanol, phenol, methylene chloride, and some simple organic compounds containing nitro groups with a special emphasis on identifying reaction steps that involve hydroxyl radical and hydrogen peroxide.
