Thermodynamic availability is briefly reviewed, emphasizing its application to steady state flow systems undergoing physical or chemical changes. While thermodynamic availability provides an upper fixed bound for the energy performance of an industry, the creation of entropy provides a lower evolutionary one. These concepts are applied to the petrochemical industry, a representative large interactive system. The objectives: maximization of availability change, minimization of entropy creation, are formulated as large linear programming problems, whose solutions provide two bounding structures for the sector.
