A compact Selective Catalytic Reduction (SCR) system comprising a gas flow inlet system, a vaporizer module and an SCR reactor is described. The inlet flow system is configured to provide heat to the vaporizer module, to mix reductant with the exhaust gas and to provide an approximately uniform flow of the exhaust gas through the catalyst. The vaporizer module is configured to vaporize reductant from a solution of a reductant or a precursor of a reductant and to transfer the vaporized reductant into the gas flow inlet system, where it is mixed with exhaust gas. The SCR reactor contains and SCR catalyst is in fluid communication with the inlet flow system and the vaporizer module.

Compact selective catalytic reduction system for nitrogen oxide reduction in the oxygen-rich exhaust of 500 to 4500 kW internal combustion engines

A very compact Selective Catalytic Reduction (SCR) system with a very low footprint comprising an SCR reactor, an inlet flow system, and a vaporizer module is described. The SCR reactor comprises at least one SCR catalyst which is in communication with the inlet flow system and the vaporizer module. The inlet flow system is configured to provide an approximately uniform flow of the exhaust gas through the catalyst and to provide heat to the vaporizer module. The vaporizer module is configured to allow for the conversion of urea to ammonia and to contact the ammonia with the exhaust gases in the SCR reactor upstream of the SCR catalyst.
