Visually Inspecting Your Catalyst Bed
Yesterday, we talked about the importance of your catalyst bed in VOC destruction. How do you visually inspect the catalyst bed in your catalytic oxidizer? What are you looking for?
If you have a monolith (block) catalyst, you'll want to check for loose hold-down clamps or a damaged gasket. Loose catalyst blocks or damaged gasket and seals can allow the bypass of air around the blocks, reducing VOC destruction.
If you have bead based catalyst beds, check the height of beads in the bed. If they're too low, top them off with new catalyst. A small reduction in the bed height with small (1/8”) beads can result in channeling of airflow through the bed, as air pushes the beads aside.
If you're still not achieving VOC goals, take a catalyst sample. You'll need to check with the OEM in order to find out how. Have the sample tested to determine performance of the catalyst under laboratory conditions. If you get poor performance, replace a portion or the entire catalyst bed based on the recommendation of the tester. If you need to replace the bed, don't worry. Kono Kogs has an inventory of new and of high performance used catalyst available at all times as well as other used air pollution equipment. Contact us for availability and pricing.
But what if it's not the catalyst bed? What's the next step?
