  • Patent number: 5005495
    Abstract: Apparatus (10) and a method for removing volatile organic contaminants from particulate material utilizes a particulate material processor (12) and an emissions processor (14) which includes recirculating emissions pretreatment circuit (16) and a final treatment system (18). The recirculating emissions pretreatment circuit (16) has an inlet (72) that receives the contaminated hot gas emissions from a heating unit (20) of the material processor (12) and also has a condenser (76) that is preferably embodied by a wet scrubber (88) for removing condensible gases from the emissions prior to passage through an outlet (78) thereof back to the heating unit (20). An inlet (82) of the final treatment system (18) has a fan (48) that draws off a portion of the pretreated emissions for a final treatment. This final treatment may be provided either by a flame burner that is most preferably a part of the heating unit of the particulate material processor (12) or by a carbon adsorber (144).
