Abstract Information :

In the US, we have multiple regulations related to monitoring particulate matter (PM). Each with different levels of quality assurance (QA) and quality control (QC) requirements. Over the last 10 years the US compliance market has been focused on the particulate matter (PM) continuous emission monitoring systems (CEMS). However the US EPA has two (2) other methods for compliance monitoring related to PM, continuous parametric monitoring systems (CPMS) and bag leak detectors (BLDs).

This presentation will review the regulatory requirements of each method and compare the results, from several data sets, of the PM CEMS and PM CPMS methods. We will also show that lower PM concentrations are great for compliance, but can provide difficulties when using the CPMS method of compliance. The lower PM concentrations means developing a relationship with the analyzer in the low part of the output range that is intended to represent the entire monitoring range. However it is very difficult to develop a representative relationship for the full range of any instrument by only using a limited range of data. This presentation will provide data comparing the CEMS results versus the CPMS results to illustrate the issues with using a limited data range to establish an overall relationship for the PM monitor.

It seems that all of the new regulations and emission monitoring requirements has taken our focus away from the basic issue, which is to lower PM. We will provide an overview of how some US companies are investing in advanced maintenance monitoring of their baghouses to insure compliance and reduce compliance related costs.
