Abstract

Abstract An air or gas filter or scrubber adapted for disposal downstream from an air or gas compressor, for removing hydrocarbons from the compressed air or gas stream. The scrubber comprises an enclosure containing an elastic bed of curled fibrous material of generally open pore nature through which the compressed air or gas passes, with such bed scrubbing the air or gas and soaking up and retaining hydrocarbons, dirt and other contaminants. A drain is provided in the bottom of the enclosure for removing hydrocarbon and other contaminant solution from the mechanism as it drains down from the bed. The bed material may have a bulk density of between approximately 12 to 22 pounds per cubic foot, and results in very little pressure drop through the mechanism.
