Advanced FTIR Technologies and Method Comparisons of Results
Many facilities have traditionally struggled with determining their true emissions due to instrument capabilities. Actual emissions such as formaldehyde and other compounds of interest from combustion and other emission sources can be lower than the detection limits of the standard test methods. Furthermore, existing emission factors can seriously over-estimate the emissions in many cases as they were developed using older, less sensitive methods. New enhancements to existing methods and emerging technologies can provide actual emission results at measurable and defendable levels.
We will discuss which new optimized techniques are currently being used to measure HAPs, VOCs, BTEX, etc. emissions at much lower concentrations than can be detected using the standard methods. These enhancements can provide continuous and real-time data useful in combustion tuning, compliance, engineering, and demonstration of combustion or post-combustion controls. These measurements have verified that some sources emit much lower than the proposed limits. (Starboost, GC-MAX)
Data from several in-field testing programs will be reviewed to illustrate the issues with the standard methods and the improvements provided by the enhanced techniques. A few of the enhanced FTIR techniques will also be discussed. We will also hypothesize the potential pathway for FTIR testing and our vision of the future in enhanced data collection.
