OIL SPILL FUMES REMOVAL
As a result of the oil spill in the Gulf of Mexico, we are now are faced with the challenge of removing the odors associated with that spill. While each individual application is different, here are a few guidelines to help provide you with the most economical yet functional filter.
Media Selection: Crude oil, which consists of mostly high-molecular-weight compounds that are well adsorbed with activated carbon, also contain hydrogen sulfide, which will require either an impregnated carbon or potassium permanganate impregnated media. The human nose can detect sulfur compounds at very low levels, so while addressing the issue with straight activated carbon, you might remove the majority of the contaminants, but you might not eliminate the odor.
Filter Selection: Filter selection is much more application oriented. A number of factors must be considered, including space, pressure drop, change out frequency, and the efficiency required for effective odor removal.
Outside air: V-Bank filters from 6”-12” deep are generally recommended in these applications to insure that odors are removed effectively in one pass. These filters offer higher media weight, low-pressure drop, and good one-pass efficiency.
Recirc air: A thin bed filter 1” or better may be used in this application since there are repeated opportunities to remove the odors. However, as the absorbent media is constantly being challenged with contaminants, the life of these filters will be significantly shorter due to minimal carbon weight.
