A railcar manufacturer in the Midwest will utilize a regenerative thermal oxidizer for the abatement of volatile organic compounds (VOCs) from the interior lining process.

The 8,000 scfm regenerative thermal oxidizer, manufactured and supplied by Catalytic Products International (CPI), will control VOC emissions containing toluene, MEK and xylenes from two interior lining booths at a new railcar repair and relining facility. The RTO will control the VOC emissions with 98 percent destruction rate efficiency (DRE) and 95 percent thermal efficiency, according to CPI.

Thermal treatment of VOCs and other air pollutants works by a chemical reaction of the hydrocarbon-based air pollutants with oxygen and heat. In this environment, the VOCs are oxidized to form inert byproducts like CO2, water vapor (H2O) and usable heat. These byproducts are released to the atmosphere or used within primary or secondary energy recovery techniques to lower operational costs.

CPI provided a turnkey installation of the VOC abatement system that included interior process ductwork, exhaust system and stack and dampers.
