As usual, industrial process systems operate far from (stable) equilibrium. Under practical operating conditions when putting the system back in equilibrium, this gives rise to the loss of energy (or certain generalized energy). Following the second law of thermodynamics, an irreversible process generates entropy. On the basis of this property, we propose an approach that allows to investigate quantitatively the amount of (generalized) energy lost when the system reaches equilibrium. A liquid phase reactor modelled with the CSTR (continuous stirred tank reactor) in which the acid-catalyzed hydration of 2-3-epoxy-1-propanol to glycerol subject to steady state multiplicity takes place is used to illustrate the
results.
