Regenerative Thermal OxidizerEach of the company’s regenerative thermal oxidizers system is custom designed to achieve the desired performance, and each system goes through exhaustive front-end and preengineering analysis. Based on that analysis, the company designs, drafts and manufactures the system. Each oxidizer is designed to be an energy-efficient system that achieves high levels of VOC destruction to keep processes well below required DRE emission levels. The company also has experience with handling exhaust streams with VOCs, hydrocarbons, solvents and HAPs as well as particulate-laden processes that generally require prefiltration prior to the oxidizer.

Enterprise Il achieves regulatory compliance with a compact two-canister system. Compared to three-column regenerative thermal oxidizer designs, the system operates on longer cycle times, at higher temperatures and with fewer moving parts, according to the manufacturer. It uses engineered ceramic heat exchange media that provides even process air distribution across the column while promoting turbulence. It achieves a standard VOC destruction rate of up to 99 percent.

Regenerative Thermal Oxidizer
Regenerative thermal oxidizer destroys hazardous air pollutants (HAPs), volatile organic compounds (VOCs) and odorous emissions that are discharged from industrial processes. Oxidizer achieves emission destruction through the process of high temperature thermal or catalytic oxidation, converting the pollutants to carbon dioxide and water vapor while reusing the thermal energy generated to reduce operating costs. Once oxidized in the combustion chamber, the hot purified air releases thermal energy as it passes through the media bed in the outlet flow direction. The outlet bed is heated and the gas is cooled so that the outlet gas temperature is only slightly higher than the process inlet temperature. Poppet valves alternate the airflow direction into the media beds to maximize energy recovery within the oxidizer. The high energy recovery within the oxidizers reduces the auxiliary fuel requirement and saves operating cost.

Designed for low concentration, large airflow applications in which the exhaust stream is at or near ambient temperature, the rotary concentrator/regenerative thermal oxidizer system is designed to remove and destroy VOCs and HAPs generated from a facility’s production process. The system performs a multistep process: removal of the VOC/HAP from the process airstream using a hydrophobic Zeolite rotating wheel; desorbing or removing the VOC/HAP from the Zeolite with a reduced airstream; and destruction of the concentrated VOC/HAP using an oxidizer.

VOC Abatement System
Retox provides more than 99 percent VOC control with low-pressure-drop ceramic heat exchangers rated at 95 percent primary heat recovery, providing fuel-free operation at 3 percent LEL and greater inlet VOC loadings. The dual-chamber regenerative thermal oxidizer offers flameless, NOX-free operation with the oxidizer burner only used for initial cold startups. Secondary hot air, chilling and hot oil heat recovery also are feasible for many applications.
