Abstract
An apparatus and method for removing volatile organic compounds (VOCs) from a stream of contaminated air using an adsorbent material. The stream of contaminated air is introduced into an end of a first hollow member which contains the adsorbent material. A perforated member disposed within the hollow member is configured to increase the air stream velocity such that dispersed particles of the adsorbent material are entrained in the air stream. Entrainment of the adsorbent in the contaminated air stream facilitates efficient removal of the VOCs. The cleaned air stream exits from a second end of the first hollow member, and the adsorbent material, having a quantity of VOCs adsorbed thereon, is directed to a reconditioning apparatus wherein the VOCs are thermally desorbed. The reconditioned adsorbent material is then returned to the first hollow member.
