Abstract: An apparatus and method for removing volatile organic compounds from an air stream wherein airborne adsorbent material is mixed with contaminated exhaust air in a vertical main column. Volatile Organic Compounds (VOCs) within the exhaust air adhere to the adsorbent material and are thus removed from the air. The clean air exits the system and the saturated adsorbent material falls through the bottom of the main column and into a lower reservoir. The saturated adsorbent material is desorbed and recycled through the adsorber apparatus by being drawn up from the lower reservoir through a secondary column and deposited at the inlet to the main column. At the top end of the main column, the adsorbent material is once again dropped into the contaminated exhaust air flowing through the main column. This process is constant and adsorbent material is continuously being recycled through the system.

Abstract: A volatile organic compound (VOC) incinerator that is designed for installation in the exhaust airstream of VOC generating equipment. The incinerator includes an intake end, combustion chamber and an exhaust end. A flame baffle is disposed within the combustion zone to cause mixing of the VOC plus hot air mixture to increase efficiency and reduce fuel requirements. A temperature sensor is disposed within the combustion zone of the combustion chamber of the incinerator to monitor the combustion temperature to provide temperature signals to a controller. An air flow rate sensor is engaged in the intake end of the incinerator to provide air flow rate signals to the controller. The controller regulates the quantity of fuel injected into the VOC plus air mixture based upon the air flow rate signals and the temperature signals. A VOC detector is disposed in the intake end of the incinerator to provide a signal that turns the unit on or off depending upon the presence or absence of VOC's in the airstream.
