Abstract: A system for the adsorption of volatile organic compounds from a contaminated gas stream. The system includes a filter for the removal of particulates from the stream, and a blower which draws the stream through the filter and transports it to a first granulated carbon filter which includes inner capillaries or passages for adsorbing substantially all of the volatile organic compounds from the contaminated gas stream. The resulting low-vapor stream is then discharged to the atmosphere through a stack. Control structure is provided for diverting the flow of the contaminated gas stream from the first carbon filter to a second carbon filter when an analyzer detects a concentration of volatile organic compounds above a given level in the low vapor stream. A regeneration device removes volatile organic compounds from the first carbon filter when the contaminated gas stream has been diverted to the second carbon filter.

Abstract: A pollution control system includes a condenser and filtering unit for removing vaporized organic solvents and particulate matter. The condenser includes baffles that define vertical flow paths, and hot exhaust gases are directed from above to alternate flow paths to flow downward while atmospheric air is directed upwardly through the remaining flow paths to cool the exhaust gases and the heated air is used to maintain the atmospheric air above a selected temperature. The filter unit includes a horizontal movable filter which is automatically replaced with a new filter section when the pressure differential across the filter exceeds a certain level.
