Following 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 summer of 2005. The purpose of the study was to evaluate the ability of the CCS to treat particulate and SO2 emissions from the exhaust of glass melting furnaces. Data from the pilot study was the basis on which Tri-Mer designed commercial systems for installation on existing and future furnaces as required by state and federal regulations. In addition, the pilot study was used to optimize the hardware configuration, demonstrate reliability, and validate the process control design of the CCS for glass melting furnaces.
Third-party testing was contracted by the glass company to source-test the inlet and outlet of the CCS using EPA Method 5/202 for particulates.
For PM, three 1-hour tests were conducted for each of four differently-configured glass melting furnaces. The results of these tests showed that the CCS could remove filterable particulates in excess of 95%, total particulates (including condensables) in excess of 90%. Other tests conducted independently by Tri-Mer, and accepted by experts with the hosting glass company, showed that the CCS could remove total particulates in excess of 99%. A summary of the tests cconducted by Tri-Mer using more advanced methods and testing equipment is shown in Graphic 1.
