Description:
This report describes a test program conducted at a paint bake oven facility. The purpose was to measure total hydrocarbon (THC) concentrations at the inlet and outlet of an incinerator with heat recovery used to reduce organic solvent emissions. Data were also collected to evaluate the energy efficiency and economics of the system compared to other THC control alternatives. The incinerator system was designed by Schweitzer Industrial of Madison Heights, Wisconsin, and incorporates DuPont's Torvex catalyst with platinum to enhance hydrocarbon reduction in the process stream. The incinerator system includes a heat exchanger following the catalyst bed. The heat exchanger 'effectiveness' of this configuration was 82 percent, allowing for a recovery of 35.1 percent of total thermal energy from the gas stream. Analysis of the annualized costs of thermal and catalytic incineration and carbon adsorption was performed. Because the concentration of hydrocarbons to the control device is small, the annualized cost of carbon adsorption is less than other control devices. Measurements conducted at the inlet and outlet of the incinerator indicate an average reduction in emissions of approximately 86 percent. Bypassing the incinerator with a fraction of the total gas stream resulted in an emissions reduction to the atmosphere of 70 percent.
