Follwing other successful applications in the glass industry, a pilot study to evaluate the performance of a Cloud Chamber Scrubber (CCS) system was completed in the fall of 2005. The purpose of the study was to evaluate the ability of the CCS to treat emissions from the exhaust of two different types of fiberglass forming lines for particulates.
One line utilized a formaldehyde-based phenolic resin binder; the other produced wool for blowing applications and did not use a binder. In addition to particulate removal, the CCS was evaluated for its ability to manage the large fibers that are often entrained in this exhaust stream. The concern was that these fibers would cause unacceptable maintenance issues in the recirculation system of the scrubber, such as clogging of the spray nozzles and mist eliminators. Data from the pilot study has been used to develop a design for use on several large industrial installations.
A third-party testing company was retained by the customer to source-test the inlet and outlet of the CCS using EPA Method 5/202 for particulates and condensables. The proprietary results confirmed to the glass company host that the CCS demonstrated superior performance compared to conventional equipment currently in use, and the pilot tests were a valuable exercise in preparation for new regulations anticipated at existing and new locations.
Tests conducted independently by Tri-Mer on the pilot unit showed that the CCS could remove filterable and condensable particulates to concentrations less than 0.001 grains/dcf.
