Thermal treatment 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 harmless inert byproducts, water vapor (H2O), and usable heat. These harmless by-products are released to atmosphere or use an energy recovery technique to further lower the operational costs.
TRITON II-Series RTO's are considered among the world's most advanced recuperative thermal oxidation systems. These specially designed and proven systems combine the basic principles of time, temperature, and turbulence – matched to industry leading construction and design features. All resulting in exceptional performance, substantially reduced operating costs, and industry-leading reliability.
The TRITON II-Series Regenerative Thermal Oxidizer process begins with the touch of a button, which activates the system's PLC-based Temperature Safety System (TSS). The TSS control system automatically retrieves media temperatures, selects the hottest bed for damper positioning, opens the fresh air purge/idle damper, energizes the booster fan, purges the system with fresh air, ignites the burner, cycles the valves, and gradually brings the system up to the correct operating temperature. The TSS also monitors the temperature in the regenerators, combustion chamber in three places, and in the valve assembly's inlet and outlet. 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 oxidized gases are then directed to the second regenerator to absorb the heat energy. As the ceramic media loads with sufficient heat, the Posi-Seal Valves switch, and the gases are reversed through the system where the heating and oxidation process continues.
For the spilt second that it takes for the valve switch to occur, a "puff" of un-treated gases are released to atmosphere. This small concentration of VOC lowers the removal efficiency in standard two-regenerator systems. By adding our VOC Polishing Chamber between the RTO and the exhaust stack, the TRITON II-Series RTO is able to recirculate the puff un-treated gases to the RTO for increased destruction efficiency. The VOC Polishing Chamber is comprised of a third Posi-Seal Valve and a holding vessel.
