SCR Ammonia Unloading, Storage, Distribution & Vaporization System

Modular, Engineered-to-Order, Shipped Ready to Plug In

Integrated Flow Solutions Ammonia Unloading, Storage, Distribution & Vaporization System is designed to provide ammonia (anhydrous or aqueous) reactant to a Selective Catalytic Reduction (SCR) unit for removal of NOx from flue gas.  Ammonia is delivered by truck or railcar and unloaded into storage tanks. The ammonia is forwarded to the Ammonia Flow Control Unit (AFCU) which generates ammonia gas for injection into the flue gas upstream of the SCR. IFS provides the complete system.
