Abstract:

Significant quantities of volatile organic compounds VOCs and hazardous air pollutants are released into the atmosphere during USAF maintenance operations. Painting operations conducted in paint spray booths are major sources of these pollutants. Solvent based epoxy primers and solvent-based polyurethane coatings are typically used by the Air Force for painting aircraft and associated equipment. Solvents used in these paints include methyl ethyl ketone MEK, toluene, lacquer thinner, and other solvents involved in painting and component cleaning. In this report, carbon paper adsorptioncatalytic incineration CPACI and fluidized-bed catalytic incineration FBCI were evaluated as control technologies to destroy VOC emissions from paint spray booths. Simultaneous testing of pilot-scale units was performed to evaluate the technical performance of both technologies. Results showed that each technology maintained greater than 99 percent Destruction and Removal Efficiencies DREs. Particulate emissions from both pilot-scale units were less than 0.08 grainsdry standard cubic foot. Emissions of the criteria pollutants--sulfur oxides, nitrogen oxides, and carbon monoxide--were also below general regulatory standards for incinerators. Economic evaluations were based on a compilation of manufacturer-supplied data and energy consumption data gathered during the pilot scale testing. CPACM and FBCI technologies are less expensive than standard VOC control technologies when net present costs for a 15-year equipment life are compared.
