Air Control Techniques, P.C. and Emission Monitoring, Inc. provide complete expulsion test services for the analyses of cement and lime kiln feed materials. The expulsion tests are conducted to help industrial clients evaluate:

  • Native polychlorinated dibenzo-p-dioxin and polychlorinated dibenzofuran levels in feed materials

  • Total hydrocarbon (THC) and volatile organic compound (VOC) emissions

  • Speciated organic compound (i.e. benzene, toluene, ethyl benzene, xylenes, formaldehyde) emissions

  • Ammonia emissions

These data are helpful in maintaining compliance with MACT (40 CFR Part 63 Subpart EEE and LLL) requirements, in monitoring for changes in raw material quality, and in minimizing conditions conductive to secondary plumes.

Gas Stream Analyses

The expulsion apparatus gas streams are analyzed using the following EPA reference methods and specialized test methods:
  • Total hydrocarbons and total nonmethane hydrocarbons - Method 25A

  • Speciated volatile organic compounds (except formaldehyde)- Method 18 using gas chromatograph- mass spectroscopy (services provided by Emission Monitoring, Inc.)

  • Ammonia - ammonia CEM based on dual chemiluminescent NOx analyzers

  • PCDD/PCDF compounds - Method 23 integrated over the entire expulsion system temperature range (high resolution gas chromatograph - high resolution mass spectrometry provided by Alta Analytical Perspectives, Inc.

  • Formaldehyde - Method 18 with FTIR analysis

Laboratory Procedures Expulsion tests are conducted using a blended carrier gas stream similar to that in full scale systems where carbonaceous and nitrogenous compounds are pyrolyzed and volatilized. Gases emissions are measured on a continuous basis (intermittent for speciated volatile organic compounds) and PCDD/PCDF compounds are measured on an integrated basis. A minimum of three repetitions are conducted per sample. Full quality assurance procedures are used in all gas stream analyses.

Sample results are provided in units of micrograms emissions per gram of sample (or in picograms TEQ per gram of sample for PCDD/PCDF). Concentration - gas temperature curves are provided for each run.
