Show 5'10'6 taken and analyzed for contaminates via the laboratory's gas chroraatograph and atomic absorption spectrophotometer. This verifies complete detoxification of the waste effluent streams prior to landfilling or other disposal. A control room is also located in the laboratory van. The incinerator combustion process and ancillary processes are monitored and controlled by an integrated system of analog and digital readouts, single loop controllers, and a computer system. The computer system is employed in a multifunction role, providing data acquisition and display as well as operational process control. Single loop controllers are utilized to regulate combustion air flow, fuel flow and boiler drum level. Single parameter readouts, mounted on a graphic panel, are used to monitor process temperatures, waste water flow, quench water flow and scrubber water flow. The system has built-in signal conditioning electronics and measurement signals are directly wired to it. These signals include thermocouple millivolts, pressure transmitter milliamps, and milliamp/millivolt signals from the four combustion gas analyzers. Signal scaling to engineering units is accomplished through digital processing as directed by a portion of the software. Calculated prameters such as combustion efficiency and gas flows are also generated, displayed, and logged by the computer. The MWP-2000-ER unit is now contracted to destroy hydrocarbon contaminated sand and water at a contaminated lagoon and site closure in the Southeast. This operation will not use the liquid incineration trailer or the neutralization trailer. Table I summarizes the anticipated destruction test parameters that is expected at the contaminated pond clean-up operations. ^ |
