Zusammenfassung:	There is provided an exhaust system for the treatment of a humid exhaust gas comprising ammonia in an amount of up to 250 ppm, the system comprising: a dehumidifier system comprising a humid air inlet for providing a flow of humid exhaust gas; an exhaust gas inlet for providing a flow of dehumidified exhaust gas; an ammonia storage material arranged to receive the dehumidified exhaust gas from the exhaust gas inlet; an ammonia oxidation catalyst arranged downstream of a selected portion of the ammonia storage material; and a heating device for heating gas before it passes through the selected portion of the ammonia storage material to release ammonia stored therein for treatment on the ammonia oxidation catalyst; wherein the system is configured so that the selected portion of the ammonia storage material changes over time; and wherein the flow of dehumidified exhaust gas provided by the exhaust gas inlet is received from the dehumidifier system.
