An existing ClO2 (chlorine dioxide) scrubber tower at a pulp mill was repacked during a planned maintenance shut down. As the result of replacing 3" Kynar and 2" CPVC Norton Super Interlox saddles with Q-PAC from Lantec Products, the scrubber tower is now operating at a greatly reduced pressure drop compared to when the tower was packed with saddles. The reduced pressure drop has resulted in a significant power savings for mill. Immediate savings of over $80,000 per year in reduced power cost has been realized by the mill. The ClO2 emissions from the scrubber to the atmosphere are also now below detection level with Q-PAC in service in the tower.
