Considering process economic along with operational and controllability requirements is the routine for recent control structure selections studies. One of well–known studies is the Back Off theory that denotes extent of economic loss due to unmanageable and unpredictable disturbances and uncertainties. Parallel to the economic Back Off theory as a measure of economy and controllability in process system an exergy–based back off calculation is developed in this work to have a measure of energy efficiency of process systems. This new idea was applied to a reactor–separator system and was found that an steady–state exergy loss of about 10% is for the maximum back off due to worst case feed temperature and composition disturbances<\div>
