Selective Catalytic Reduction Systems
EMISSIONS REDUCTION FOR GAS TURBINE & ENGINE POWER GENERATION
Addressing Emissions Challenges
As power producers face increasingly stringent emissions requirements, reliable emissions control has become a critical part of project success. Whether the application involves simple-cycle gas turbines, combined-cycle gas turbines, or natural gas engines, emission reduction equipment must be engineered for the specific exhaust conditions, operating profile, and site requirements of the project.
Zeeco combines combustion knowledge, environmental systems expertise, and project execution capabilities to support customers across a wide range of power generation applications, delivering reliable performance and emissions compliance under demanding operating conditions.
Zeeco Selective Catalytic Reduction (SCR) Systems are engineered to:
- Achieve ultra-low-NOx emissions
- Lower the ammonia slip rate percentage at the stack outlet
- Reduce CO, VOC, and formaldehyde emissions (when required)
- Reduce noise to meet the project requirements
- Support fast-track project schedules
SCR Systems by Application
SCR Systems for Simple-Cycle Gas Turbines
Simple-cycle gas turbines are commonly selected
when rapid start-up, operational flexibility, and high power density are priorities. These applications often require emissions reduction systems that can
respond to changing load conditions while fitting
within compact site layouts.
Zeeco supports simple-cycle gas turbine projects
with engineered SCR systems tailored to each
turbine's specific exhaust characteristics, load variability, and site-specific constraints, ensuring reliable performance and efficient system integration.
SCR Systems for Combined-Cycle Gas Turbines
Combined-cycle gas turbine applications introduce additional integration considerations, particularly where exhaust gas passes through duct burners and other downstream equipment. Zeeco applies its experience in steam and power generation to
engineer SCR systems that integrate seamlessly
with the broader exhaust system while maintaining emissions performance, efficiency, and operational reliability.
