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.
