Challenge
A refinery contracted Envent to use our EVAC 1000 unit to do temporary odor and vapor control for its sludge processing centrifuge operations.

Solution
We brought out three scrubbers; the first scrubber was a dual GAC passive scrubber, the second was a dual GAC passive scrubber following Diesel sponge oil, and the third was our EVAC 1000, with our custom VapoScrub™EX5 scrubbing solution.

Benefit
With carbon following our VapoScrub™EX5 solution we were able to make the GAC last approximately 3 times longer savings the customer approximately $150,000.
