The CPI CONCORD SCR system is engineered for industrial process sources — calciners, process heaters, chemical plants, pharmaceutical facilities, rubber operations, and food processing lines — where NOx emissions must be reduced to meet air permit requirements. Unlike diesel aftertreatment systems or large utility SCR installations, the CONCORD is designed for the mid-market industrial applications that CPI has served for decades: variable flow rates, complex exhaust compositions, and strict state-specific permit limits. NOx reduction efficiencies of 90–95%+ are achievable depending on application design.
The CONCORD SCR process uses a catalyst to selectively reduce NOx — nitric oxide (NO) and nitrogen dioxide (NO2) — to harmless nitrogen and water vapor using ammonia or urea as a reductant. CPI engineers the reductant injection system, catalyst bed, and controls for each specific application, accounting for exhaust temperature, flow rate, NOx concentration, and the presence of other compounds such as VOCs, CO, or particulates. Ammonia slip — residual unreacted ammonia in the treated exhaust — is managed through catalyst design and continuous monitoring.
Industrial facilities typically require SCR when air permits mandate NOx reductions that combustion modifications alone cannot achieve, when Best Available Control Technology (BACT) determinations specify catalytic NOx control, when existing equipment is no longer meeting permit limits, or when process expansions trigger new major source thresholds under the Clean Air Act. CPI works with environmental consultants and EHS teams throughout the permitting process — from initial feasibility and budgetary cost estimates through equipment installation and ongoing maintenance support.
Where both VOC and NOx control are required, the CONCORD SCR can integrate a VOC catalyst to operate as a coordinated, single-source system.
