Selective Catalytic Reduction (SCR) is a commercially-proven NOx control technology for stationary combustion sources. Fossil Energy Research Corporation (FERCo) is an engineering company assisting the power generation and oil refining industries with designing, optimizing and troubleshooting SCR systems. Previous projects have ranged from small (3 MW) gas turbines to large (1300 MW) coal-fired utility boilers. FERCo has developed a number of tools along the way, including a process model to simulate SCR performance and a system for determining catalyst activity in situ. This presentation provides an overview of SCR technology and describes the key factors for successful system design and operation.
