Case Studies Case StudiesTri-Mer technology for controlling sulfuric acid fumes from dry charge formation operations offers high collection efficiencies at all loadings.
Originally developed for East Penn-Deka, (Lyon Station, PA), the system uses mechanical separation, rather than chemicals.
Goals set by East Penn included operation “24/7” with zero shutdown, and collection efficiency greater than 99%.
East Penn consulted Tri-Mer, whose Fan/Separator, Crossflow fume scrubber and Whirl / Wet lead oxide collector systems all had solid track records within battery forming. What emerged was UltraScrub, a hybrid, scalable technology that incorporated key features from those systems.
At East Penn, the first phase of a 3-phase program employed six UltraScrub units, installed side-by-side. Each is ducted to a single 9' diameter plenum. This configuration allows any unit to be shut down for annual maintenance or other purposes and restarted seamlessly. Five units operate continuously; one is a maintenance back-up. The acid scrubber units, which are UV-stabilized polypropylene, each have a capacity of 32,000 cfm.
The order to design, build and install the first three UltraScrub units, along with plenums, fans and stacks, was fast-track: lead time to just 65 days.
East Penn is of the world’s leading battery manufacturers, with over 8,000 employees, 450 product designs, and hundreds of awards for manufacturing and environmental excellence.
