Abstract : A catalytic oxidation unit, also commonly known as a catalytic incinerator, is an emission control device to treat air streams contaminated with volatile organic compounds (VOCs). At Wurtsmith AFB (Oscoda MI), a catalytic oxidation unit treats the effluent air from an air stripping operation which transfers VOCs, chiefly trichloroethylene (TCE), from groundwater to air. Air stripping has been proven to be effective and economical for removing VOCs from groundwater; however, some states require that an emission control device be used in conjunction with the air stripping unit since air stripping merely transfers the VOCs from the water phase to the air phase. Incineration Is an attractive choice for emission control since the contaminants are destroyed on site. A catalytic oxidation unit is preferred to a thermal incinerator because the unit operates at a lower temperature to obtain high destruction efficiencies so less fuel is required to operate the catalytic oxidation unit. The purpose of this project was to evaluate the catalytic oxidation unit at Wurtsmith AFB. The results obtained from this study indicated that the catalytic oxidation unit at Wurtsmith AFB destroys TCE with 99 percent efficiency when it is operated at the vendor recommended catalyst bed temperature of 370 deg C (700 deg F) and when the unit contains yields 19 cm (7.5 inches) depth of catalyst as indicated by the pressure drop across the catalyst bed. ...
