Description:
The report gives results of the characterization of organic emissions resulting from the pilot-scale incineration of trichlorofluoromethane (CFC-11) and dichlorodifluoromethane (CFC-12) under varied feed rates. (NOTE.- As a result of the Montreal Protocol, an international accord implemented to reduce the production and use of stratospheric ozone depleting substances, considerable quantities of chlorofluorocarbons (CFCS) and halons may be accumulated and ultimately require disposal or destruction. Incineration is a potential destruction technology; however, little is known of the combustion emission characteristics from CFC incineration. ) A 293 kill (1 million Btu/h) incinerator was made available to the EPA for the characterization, which focused on determining the destruction efficiencies (D-E$) and major products of incomplete combustion (PiCs) for each CFC evaluated. Sampling was performed to screen for volatile and semivolatile organic emission products including chlorinated aliphatics, chlorobenzenes, chlorophenol, polychlorinated dibenzodioxins and furans (PCDDs and PCDFS), and polyaromatic hydrocarbons (PAHs). Results indicate that 99.999% DE can be achieved at a CFC-11 feed rate as high as 69% by mass. The formation of volatile and semivolatile organic PICs was minimal. Less than" concentrations are presented for target analytes not detected.
