EXHAUST GAS TREATMENT SYSTEM AND METHOD |
abstract |
An aftertreatment system for treating exhaust gases exiting an engine includes a first selective catalytic reduction (SCR) device in fluid communication with the engine. The first SCR device receives the exhaust gases exiting the engine to reduce a first amount of nitrogen oxides (NOx) present in the exhaust gases. The aftertreatment system also includes an oxidation catalyst in fluid communication with the first SCR device. The oxidation catalyst receives the exhaust gases exiting the first SCR device to oxidize ammonia present in the exhaust gases into a second amount of NOx. The aftertreatment system further includes a second SCR device in fluid communication with the oxidation catalyst. The second SCR device receives the exhaust gases exiting the oxidation catalyst to reduce the second amount of NOx. |
