Twenty Years Specializing in Air Pollution Control by Catalysis, SCR NOx Reduction, and Platinum Group Metals Technologies and Markets. Our Materials Characterization and Catalyst Development Laboratory performs Novel Research, Benchmarking and Catalytic Activity Testing.

SCR Design Services

Environex SCR designs operate reliably in the field.  Our design services include the measurement of critical parameters for the design basis. We review other designs for their operability and cost.  Our design experience covers SCR's for combustion turbines, IC engines, coal boilers, process/refinery heaters, waste incinerators and many other sources. We evaluate quotes for catalysts and systems for end users.

Our engineers objectively evaluate your SCR system needs and arrive at a plan of action to adopt designs that keep you operating in compliance.

With over 20 years of experience in the industrial SCR catalyst design and testing, we help you with:

  • Procuring Replacement Catalyst
  • Specification and Bid Review
  • SCR System Design
  • Ammonia System Design
  • Custom Catalyst Applications
  • SCR System Audits
  • Air Permitting
  • Urea System Design Review
  • Pilot Scale Testing
  • In-Situ Testing
  • Reactor Performance Model
  • Risk Assessment

We solve SCR problems  with solutions that range from simple changes in operating procedure though modification or re-engineering of poorly designed or sized systems. Owners retain us for our expertise in initial and replacement catalyst bid reviews to choose the best solution for their situation and needs. With experience on hundreds of SCR applications, we understand the complex issues that arise from balancing the permit requirements with practical plant operation.
