Abstract: An exhaust gas treatment system for an internal combustion engine to control desulfurization of at least one aftertreatment device is provided. The exhaust gas treatment system includes a desulfurization mode trigger module, a desulfurization control module, and an interrupt module. The desulfurization mode trigger module is configured to set a desulfurization request based on one or more trigger conditions. The desulfurization control module is configured to control desulfurization of at least one aftertreatment device based on the desulfurization request. The interrupt module is configured to interrupt the desulfurization of at least one aftertreatment device based on an interrupt condition.
