Hypertargets: a Conceptual Programming approach for the optimisation of industrial heat exchanger networks - Part III. Industrial applications

The fundamentals of the grassroots and retrofit technology have been presen ted in Parts I and II. This part emphasises on common complications associa ted with deviations from the counter-current heat transfer, and the integra tion of streams with properties that face significant variations over the p erceived range of energy recovery. A number of propositions are made with s imple and straightforward modifications to the conceptual models. The modif ications save the need to revert to elaborate, simulation-type models that can mire the benefits of the systematic approach. The paper further discuss es the application of the technology to problems of special importance such as debottlenecking projects. It explains its potential as an analysis and a decision making tool with an example from the pulp and paper industry. A final test of its potential to remain systematic, rigorous, and fully autom ated, even against large scale, complicated problems, is illustrated with t wo Crude Oil distillation applications.
