Baghouse experts would agree that the only way to determine long term viability of a new baghouse application is to review performance after a minimum of 6 months and preferable a year of operation. The technical approach proposed in this effort is designed to gather both the necessary long-term data and to investigate supporting technologies that might provide improved economics or performance.

A commercial sorbent injection system will be procured that will allow for continuous operation with minimal O&M requirements. COHPAC performance will be evaluated using existing diagnostic equipment and with periodic, in-situ fabric drag measurements. Mercury measurements will be made with a dedicated mercury analyzer capable of measuring speciated, vapor phase mercury. Resources are set aside to optimize operation of the mercury analyzers to minimize on-site support. At a minimum, continuous mercury measurements will be made one week per month and during certain test periods. To reduce risk to the host site, a new set of bags will be purchased in case of irreparable degradation to the existing bags. In addition, if new, high performance fabrics are available, we will work with EPRI and the developers to install and monitor limited numbers of these bags. After performance is optimized with the benchmark sorbent, it will be possible to perform short-term evaluations of up to 3 alternate sorbents.
