Measurement and control of dioxins and furans from a hazardous waste incinerator
- Rollins Environmental Inc./ENCOTEC, Ann Arbor, MI (United States)
- Rollins Environmental Inc., Wilmington, DE (United States)
Rollins Environmental Services (RES) Inc. owns and operates five hazardous waste incinerator (HWI) facilities subject to the hazardous waste combustor maximum achievable control technology (MACT) polychlorinated dibenzodioxin and polychlorinated dibenzofurans (PCDD/F) standard proposed by the Environmental Protection Agency. Complying with MACT will require HWIs, including those owned by RES, to evaluate current dioxin emission levels. Observations will include method detection limits and precision, effects of estimated maximum possible concentration (EMPC) results, split sample analysis, and PCDD/F signature differences. Method detection limits were evaluated and established based on analytical detection limits of 0.05 ng (or less) and two hour sample times. The resulting in-stack detection limits were 0.015 ng/dscm or less. The precision results, generally less than 30%, indicate that the method performance is adequate for evaluating the PCDD/F emission reductions due to the carbon injection system. The effects of removing EMPCs from the data were investigated. Most showed a percent difference of less than 10% between treating EMPCs as non-detects and treating them as confirmed detections (these numbers were based on treating reported non-detects as zeros). The split sample analysis as proposed in Method 0023A is found to be promising projects involving carbon injection. Split samples collected after carbon injection ranged from 30 to 90 percent in the particulate phase. This shows that the PCDD/F were transferred from the vapor to particulate phase by the carbon injection. This information provides the bases for future engineering considerations. Thus, capture of the fine, non-polar particulate has become the major engineering challenge.
