Selective Catalytic Reduction (SCR) Experts
What We Do

We do Emission Solutions

Power plants need efficient flue gas cleaning methods to reduce CO, NOx and maintain NH3. (ammonia) slip. Our SCR (selective catalytic reduction) services use years of hands-on experience to solve problems with poor flow, ammonia or temperature distributions in high reduction applications.

SCR Testing & Optimization
Poor flow distribution can have huge effect on system performance.

​AIG Tuning & Design Services
AIGs should be designed with ability to tune as much as possible. Systems designed with no tuning capability have very limited flexibility.

SCR Solutions Retrofit Helps MID Woodland Generation Station Earn 2025 CCJ “Best of the Best” Award

SCR Solutions helped Modesto Irrigation District’s Woodland Generation Station earn CCJ’s 2025 “Best of the Best” Award with a high-efficiency AIG retrofit that improved NOx control, cut ammonia slip by 83%, and reduced operating costs.

Large-Scale SCR Catalyst Retrofit

SCR Solutions worked for 2+ years to develop this complicated LM6000 SCR retrofit project in Long Beach, CA. Work included inspections, CFD modeling, detailed engineering to fabricate and install new perforated plate, catalyst frames, supports, and AIG. SCR Solutions also provided onsite field supervision of the retrofit work. After the work was completed, we also did a performance test. Their stack NOx, CO and ammonia slip were all dramatically reduced from their previous operations. Overall this project was a huge success
