SCR Catalyst Systems for NOx Removal

Since 2009, ATCO Emissions Management has delivered best-in-class SCR systems for gas turbine simple cycle applications.

Our SCR Development Process

We began development of our systems in 2009 with the hiring of an SCR design team with 40 years’ experience on 30 sold units. Our team’s thorough understanding of turbine exhaust gas flow, ammonia injection and mixing, SCR catalyst selection, ammonia vaporization systems, tempering air requirements and fabrication and installation joined with ATCO Emissions Management’s 35 years of noise abatement expertise for leading-edge SCR applications.

SCR Applications

​Client:

​Los Angeles County
