Abstract
Regenerative oxidizer including an entrapment chamber and damper assembly, as well as a method of oxidizing volatile organic compounds in a gas using such apparatus. To improve the VOC destruction efficiency and eliminate opacity issues resulting from heat exchange matrix regeneration, untreated fluid can be diverted away from the oxidizer exhaust stack and directed into a “holding vessel” or VOC entrapment chamber. The assembly utilizes a single damper in order to divert the exhaust flow from the oxidizer either to exhaust or to the entrapment chamber. The entrapment chamber preferably has a modular construction, which facilitates expanding or decreasing the volume of the chamber. The design facilitates installation and can be retrofitted on existing equipment. The damper diverts the flow of gas with minimal or no negative impact on the process flow.
