CONCORD CONOx Abatement Systems are custom engineered NOx and CO abatement system in one modular package. The CONCORD is a unique abatement device designed as a combined selective catalytic reduction (SCR) NOx abatement system and CO abatement System in one convenient and integrated package.
CONCORD CONOx Systems can effectively treat greenhouse gases (GHG) such as NOx and other pollutants. Ever changing emission regulations are hard to keep up. The CONCORD CONOx System can be an effective alternative to help you stay compliantand profitable for years to come.
CPI designs and manufactures a custom NOx Abatement System in one modular package. The CONCORD CONOx System is a combined Selective Catalytic Reduction (SCR) system with add-on control for CO or other VOC's in one modular package. The CONCORD CONOx System can be economically applied to many industrial and chemical processes where NOx emissions and other pollutants are of concern.
The CONCORD CONOx Removal System engineered to provide +90% NOx removal when operated with an ammonia injection system (dry urea, anhydrous ammonia or aqueous ammonia) and specially designed SCR Catalyst. The ammonia will be precisely sparged into the CONCORD reactor and used as a reactant over the SCR Catalyst. The resulting emissions will be nitrogen, water, and minimal ammonia (slip). One of the flexibility features of the CONCORD System is its ability economically to abate another pollutant such as CO, VOC's, or HAP. The CONCORD CONOx Removal System can be fitted to include auxiliary catalyst systems for other pollutants. The exhaust from the CONCORD-CONOx Removal System will be used in a Recuperative Heat Exchanger to be used as energy conservation for the incoming gas stream.
NOx reduction is based on the efficient and safe control of an ammonia reactant over the NOx removal catalyst bed. A typical vapor delivery system may include the following components: Unload station, storage tank, pumping/delivery, vaporizer.
The CONCORD System starts in the catalytic reactor where our floating plate primary heat exchanger fabricated of all stainless steel. The counter flow of process exhaust gas with a clean oxidized air allows relatively cool operation at the leading edges of the plates. Designing the heat exchanger in this fashion allows the CONCORD CONOx Abatement Systems to operate with a broad range of operational flexibility.
The pre-heat burner developed for use in CONCORD CONOx Abatement Systems operating in a negative pressure environment. The burner is designed to promote mixing of the exhaust gasses with oxygen when fired horizontally into the burner chamber. This innovative design provides the highest degree of flame impingement and high-velocity mixing, leading to airflow and temperature uniformity for which CONCORD CONOx Abatement Systems are known.
A specially developed NOx Removal Catalyst is used based on the exact needs of the application. There are three types of catalyst that can be considered: Zeolite Catalysts offer high-temperature operation, Vanadium/Titanium Blends offer wide range flexibility, and Precious Metal blends offer low-temperature capability. Other pollutants such as CO, VOC, or HAP can be effectively treated through the use and application of other catalyst formulations.
Abatement of NOx includes the safe and accurate control of ammonia reactant. The CONCORD CONOx Removal System engineered to provide NOx removal when operated with an ammonia injection system (dry urea, anhydrous ammonia or aqueous ammonia) and specially designed SCR Catalyst. The ammonia will be precisely sparged into the CONCORD reactor and used as a reactant over the SCR Catalyst. The resulting emissions will be nitrogen, water, and minimal ammonia (slip).
Precise and accurate control of the ammonia reactant is critical to efficient NOx abatement with minimal ammonia slip. The selective catalytic reaction is simply the ionization of oxygen in the air with Hydrogen and Nitrogen molecules in the ammonia. The designed result is the reformation to harmless nitrogen (N2), and water vapor (H2O) with usable heat at low temperatures. The catalytic-induced ionization level for NOx occurs at temperatures between 450°F and 750°F. Sufficient to achieve conversion of NOx pollutants in excess of 90%. After the NOx removal catalyst, a second stage of catalyst can be used to promote additional removal of other gas stream pollutants. The exact details of the second stage reaction will be dependent on the composition of the process stream and the desired performance needs.
Auxiliary systems can be included based on the exact needs of the application. Precise ammonia reactant can be controlled via our Integral Continuous Emission Monitoring control and record keeping platform. Other components of a complete system may include ammonia delivery unload station, ammonia storage tank, pumping/delivery, and the ammonia vaporizer.
A booster fan draws the process exhaust into the system at a fixed duct static pressure. From there, the contaminated gasses are passed through the CONCORD CONOx Abatement System. The system is under constant negative pressure that eliminates fugitive leaks to the surrounding area. The resultant clean, gasses are released to the atmosphere. An advantage the CONCORD System offers is multiple sources being adequately controlled in one device. The volume control and sparge control systems work together to ensure efficient operation without any impact on the performance of the process.
CONCORD CONOx Abatement System'S meet today's environmental challenges by using the most cost effective manufacturing techniques to bring to industry reliable pollution control systems that offer lower capital costs, simplified installations, and minimal maintenance.
CONCORD CONOx Abatement System'S exceed today's air pollution control needs with:
The CONCORD CONOx Abatement Systems is fabricated entirely of stainless steel alloys designed to prevent embrittlement and fatigue.The entire unit is continuously welded to eliminate leakage and provide the highest uptime reliability.All the interior components are fully insulated with a
