A regenerative thermal oxidizer (RTO) will be used for the abatement of volatile organic compounds (VOCs) from the surface coating of Class A composite automotive body parts.

Catalytic Products International installed the 15,000-scfm system at a facility in the Southwest. It will control the emissions from a new paint system that includes a spray booth, flash-off area and drying oven. The RTO will destroy the VOC emissions with 98 percent destruction rate efficiency and a thermal efficiency of 95 percent.

RTOs operate by preheating the process air as it passes upward through the first ceramic heat exchange media. This preheated air then exits the heat exchange media and enters a combustion chamber, where it is heated to the setpoint temperature and oxidization of the VOCs is completed. The resulting hot, clean airstream then is passed through the second ceramic heat exchange media bed, where it is cooled, before being released to the atmosphere.

CPI worked closely with the paint system supplier to design, fabricate and install the RTO. As a result, a fully skid mounted, prepiped and prewired RTO with the media installed on a customer-supplied concrete pad was delivered.
