Abstract
A process for recovering performance of a component of an aftertreatment system. The component includes an inlet and an outlet. The inlet is positioned upstream relative to an exhaust gas flow through the aftertreatment system, and the outlet is positioned downstream relative to the exhaust gas flow through the aftertreatment system. The process includes removing the component from the aftertreatment system. The process also includes regenerating the component, such as subjecting the component to an acid wash and/or heat treating the component. The process further includes reinstalling the component into the aftertreatment system with the inlet positioned downstream relative to the exhaust gas flow through the aftertreatment system and the outlet positioned upstream relative to the exhaust gas flow through the aftertreatment system.
