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.
