Regenerative Thermal Oxidizer for Air Pollution Control

Thermal treatment, including Regenerative Thermal Oxidation, of VOC’s and other air pollutants works by a simple reaction of the harmful air pollutants with oxygen and heat. In this environment the VOC’s are converted to CO2, water vapor (H2O) and usable heat. These harmless by-products are released to atmosphere through a specially designed heat transfer bed, or regenerator, to minimize operating costs. RTO’s have gained worldwide acceptance as viable pollution control alternatives due to ever-rising fuel costs and environmental agencys' efforts to clean up the lowest emitters of VOC’s. In response to these conditions, Catalytic Products International has developed the TRITON - Series of RTO.

TRITON-Series Regenerative Thermal Oxidizers are custom engineered to your exact needs. Each system incorporates specialized ceramic media in the regenerator (heat transfer bed) to allow thermal rate efficiencies in excess of 97%, thus making TRITON Systems among the world's most cost effective air pollution control alternatives. TRITON RTO’s take advantage of our unique valve technology to deliver the highest destruction rate efficiencies. Designed around the stringent European tA-Luft requirements, TRITON RTO’s can confidently assure you of exceptional performance and reliability.

THE TRITON REGENERATIVE THERMAL OXIDATION PROCESS

The TRITON Regenerative Thermal Oxidation process begins with the touch of a button, which activates the system’s PLC-based Temperature Safety System (TSS). The TSS control system automatically energizes the booster fan, purges the system with fresh air, ignites the burner, and gradually brings the system up to the correct operating temperature. The TSS also monitors the temperature in the regenerators, combustion chamber, and valve assemblies. This helps safeguard the system from extreme temperature fluctuations that cause thermal stress and overall system fatigue.

As soon as the required operating temperature is reached, the TSS enables the process lines to feed into the oxidizer, or holds the system in idle mode until production is ready. When production is ready the fresh air purge damper closes and one or more of the diverting dampers open to draw the volatile organic compounds (VOC’s) off of the process lines.

A booster fan draws one or more VOC-laden exhaust from your process lines into the system. From there, VOC’s are directed into one of the systems regenerators (an internally insulated vessel containing ceramic media). The contaminated gases are passed through the first regenerator where energy is transferred from the ceramic media to the gas in order to elevate the temperature. This elevated temperature approaches the ignition level for most solvents and then is directed from the ceramic bed into the combustion chamber. As the stream exits the ceramic bed and travels through the internally lined combustion chamber minimal heat is added to ensure a proper oxidation temperature and a designed dwell time is maintained for the ultimate destruction of the streams VOC’s. The resultant clean, oxidized gases are redirected into a second regenerator bed to continue the energy transfer and oxidation cycle before being released to the atmosphere.

TRITON Systems have flexible operating parameters for a variety of processes and air compliance regulations. With thermal efficiencies up to 97% and complementary equipment such as. hot gas bypass dampers, forced draft or induced draft systems, natural gas injection, regenerator purge vessels, and bake-out cycles, you can be assured that Catalytic Products International has the right solution to your air pollution control problems.
