Product Spotlight: Regenerative Thermal Oxidizer
HOW THE TRITON-SERIES RTO WORKS
The TRITON-Series Regenerative Thermal Oxidizer system has been specially engineered to meet the extreme needs of the natural gas processing industry. The midstream gas process involves cleaning natural gas of impurities and water. When natural gas is extracted from the ground, it contains high amounts of CO2, water, and corrosive sulfur compounds. Standard processing operation includes glycol dehydration and amine stripping. The vent gas from these processes is subject to EPA guidelines; 40 CFR, Part 63, Subpart HH. Under this rule, greater than 95 percent of the pollutants must be destroyed prior to release to the atmosphere.
The typical off gas from an amine treatment system is rich in CO2, contains substantial amounts of water and varying concentrations of hydrogen sulfide (H2S). These three components combine to form a corrosive gas that has a tendency to condense and form a corrosive liquid. The gas also contains a variety of hydrocarbons such as; methane, ethane, propane, butane, benzene and others, all in varying concentrations. To further complicate the abatement plan, the gas contains no oxygen. Oxygen is a necessary ingredient when "oxidizing" VOC's.
TRITON-Series Regenerative Thermal Oxidizers are two- tower systems and all are custom engineered to your exact needs. Each system incorporates specialized ceramic media in the regenerator (heat transfer bed) to allow thermal rate efficiencies up to 97 percent, thus making TRITON Systems among the world's most cost-effective air pollution control alternative.
TRITON RTO's take advantage of our unique valve technology to deliver greater than 98 percent destruction rate efficiency. Designed around the world's most stringent emission requirements, TRITON RTO's confidently assure you of exceptional performance and reliability.
Catalytic Products International has been designing, manufacturing, and installing the world's most innovative thermal oxidizers now for over 30 years. Throughout our long history, we have continually strived to offer the most advanced air pollution control equipment. These constant efforts have led us to the development of the TRITON-Series Regenerative Thermal Oxidizer (RTO) Each system is custom engineered to exceed all worldwide air compliance guidelines at the lowest overall costs.
DESIGN FEATURES BUILT INTO EVERY TRITON SYSTEM
Modular Regenerator Technology
TRITON RTO's are custom designed for the highest reliability with the lowest overall costs. The complete system is designed with a modular approach for the most cost-efficient solution. The TRITON is supplied as a 2-tower regenerator system fitted to our Even-Flo Valve Manifold. This modular approach satisfies your needs for a competitive installation cost and ensures that the Posi-Seal valves are properly installed and aligned prior to leaving the factory.
Posi-Seal valves are designed to take advantage of a vertical axis that allows for soft seating action with self- centering guidance. The innovative feature of all Posi -Seal valves is the air tight machined seal that eliminates valve bypass and maintenance intensive gaskets. The Posi-Seal valve will be pneumatically operated and will cycle open or closed based on the program logic called for in your application.
EvenFlo Manifold Insulation
In some cases, the EvenFlo Manifold can be insulated to ensure that the pollutants that enter the oxidizer remain in a gaseous state. If the process constituents should condense at some point in the oxidizer, they can become a maintenance issue or worse yet, become a hazard to the equipment. Some pollutants will condense and collect on many of the surfaces of the oxidizers, leaving a sticky, tarry substance that is difficult to remove. Insulating our EvenFlo Manifold helps to prevent any condensation, and keeps your process air in a gaseous state.
Thermal Heat Transfer Matrix
Each TRITON system is designed around the particular ceramic heat transfer matrix recommended for the application. TRITON-Series systems can be designed using a layered structural ceramic matrix or a mix of structured and random media, depending on your application's requirements. The thermal heat transfer model is the key to a well designed and efficient system. With thermal rate efficiencies (TRE) ranging from 85 percent to 97 percent, you can be assured that even the lowest VOC concentrations can be economically destroyed.
FEATURES SPECIFIC FOR THE MIDSTREAM NATURAL GAS PROCESSOR
Catalytic Products International has worked with the world's largest natural gas processors to provide a highly reliable Regenerative Thermal Oxidizer that meets the unique needs of that midstream. These needs are unlike any found in other industry segments. The following discussion provides some basic feature descriptions.
Extensive Materials Selection – Metallurgical conformity and assessment process to ensure corrosion, and thermally resistant materials are used throughout the system.
Insulated EvenFlo Manifolds – Helps to make sure that the saturated off gas does stay hot and works to minimize condensation inside the RTO.
Complete shop assembly – gas plants located in remote areas. A drop in place installation has proven to be highly desirable. For the size ranges up to 15,000 scfm this includes; media loading, pre-wiring and extensive I/O quality control that ensures the control system is ready to operate.
Hot Air Recirculation – mixes clean hot oxidizer exhaust with cold, wet inlet gas to e
ensure re-vaporization of condensing water vapor prior to entering the EvenFlow Manifolds.
Hot Gas Bypass – Provides a method of controlling the RTO under high VOC conditions and ensures VOC destruction is maintained without cause for high-temperature shut-down.
Component Selection – API grade components are used in every TRITON System used in gas processing facilities.
Gas processors are focused on efficient operations of their plants. The modern gas processing facility understands that the gas they use in their operations is less gas they can sell downstream. Plus, recent modifications to EPA standards consider Greenhouse Gas (GHG) emissions in their inventory of emissions. Methane, the primary component in natural gas, is a GHG with a Global Warming Potential 21 times that of carbon dioxide, according to EPA.
