Purafil,Inc. | Design Considerations for the Prevention of Media Bed Fires  Winter is just beginning for a lot of us in the Northern hemisphere and record cold weather has already hit in many locations (so much for global warming!). However, our neighbors in the southern hemisphere are just approaching the warmest part of their year and summertime - whether it's in the northern or southern hemisphere - is synonymous with entertaining family and friends outdoors and cooking in the backyard. And for many, nothing smells better than beef, pork or seafood grilling over a bed of charcoal. Charcoal can be defined as black, porous material, composed mostly of carbon, that is used as a fuel, filter, and absorbent. Used as a fuel for the backyard barbeque, charcoal burns because of its high carbon content. Used as an adsorbent material, charcoal may be activated to increase its effectiveness as a filter medium. Activated charcoal, or for our purposes, activated carbon, still retains its high fuel value which has led to problems with its use in some applications. Specifically, we are referring to carbon (or media) bed fires in gas-phase air filtration systems. Where a bed of glowing coals is desirable for the grill, a media bed fire in a tank vent filter (for instance) can be catastrophic. This newsletter will provide background information on potential causes of dry-scrubbing (gas-phase) media bed fires and safety and operational recommendations for using Purafil systems; specifically when using Purafil Drum Scrubbers as vent filters for chemical storage tanks.
