An exhaust system for an engine is disclosed. The exhaust system may include a passageway configured to receive exhaust from the engine, and a recirculation circuit. The recirculation circuit is configured to recirculate exhaust from the passageway back into the engine. The exhaust system may also include an SOx removing device disposed within the passageway upstream of the recirculation circuit, and a filter disposed within the passageway to remove particulate matter from the exhaust. The exhaust system may further include a regeneration device configured to substantially simultaneously regenerate the SOx removing device and the filter.
