Recommendation (Pueblo) GA-3. Methods for monitoring the extent of corrosion in the supercritical water oxidation reactor other than by measuring effluent turbidity should be investigated. Outputs from the monitors should identify corrosion that exceeds safe operating limits, enabling operators to take corrective action when necessary. [Pg.67]

Figure ES-2 is a block diagram of the Eco Logic technology process. The primary treatment destroys the agent and the energetic materials by hydrolysis with caustic or water. Flowever, the hydrolysis products (hydrolysates) must be further treated prior to final disposal. For this secondary step, Eco Logic proposes to use a transpiring-wall supercritical water oxidation (SCWO) reactor design. The following major operations are included ...

Foster Wheeler Development Corporation (FWDC) has designed a transportable transpiring wall supercritical water oxidation (SCWO) reactor to treat hazardous wastes. As water is subjected to temperatures and pressures above its critical point (374.2°C, 22.1 MPa), it exhibits properties that differ from both liquid water and steam. At the critical point, the liquid and vapor phases of water have the same density. When the critical point is exceeded, hydrogen bonding between water molecules is essentially stopped. Some organic compounds that are normally insoluble in liquid water become completely soluble (miscible in all proportions) in supercritical water. Some water-soluble inorganic compounds, such as salts, become insoluble in supercritical water. [Pg.596]

Catalytic oxidation has been used in many wastewater treatment processes. Catalysts are now being applied to enhance supercritical water oxidation operations (Ding et al., 1998 Krajnc and Levee, 1997a). Hazardous organic pollutants can be destroyed by supercritical water oxidation at temperatures around 500°C and reactor residence times of less than 1 min, with the... [Pg.404]

Supercritical Water Oxidation (SCWO) has been proved to be a suitable process for treatment of several toxic and hazardous organic wastes due to its high removal efficiency. SCWO requires of hard reaction conditions (22.1 MPa and over 374°C). Special reactors are needed to support these conditions. An original reactor design is presented here wich has been tested in the treatment of alcohols+ammonia solutions in water. Performance results are presented here for ammonia and alcohols. Destruction efficiency greater than 99.9% are reached for both compounds, probing the correct performance of the reactor. [Pg.121]

A simple model of lumped kinetics for supercritical water oxidation included in the partial differential equations for temperature and organic concentrations allows to qualitatively simulate the dynamic process behavior in a tubular reactor. Process parameters can be estimated from measured operational data. By using an integrated environment for data acquisition, simulation and parameter estimation it seems possible to perform an online update of the process parameters needed for prediction of process behavior. [Pg.162]

For the oxidation of hazardous wastes in acidic supercritical water solutions, reactors made of alloy 625 or similar Ni-base alloys can be used, if the preheater and the cooler sections of the reactor are protected with liners made of Titanium. Some... [Pg.113]
