Industrial Heat Pumps And Efficient Energy Utilization in t h e Proceee Industries
Pinch Technology is a methodology, comprising a set of structured techniques, for the systematic application of the first and second laws of thermodynamics. The application of these techniques enables process design engineers to gain fundamental insight into the thermal interactions between chemicalprocesses andtheutility systemsthatsurroundthem. Havingsuchknowledgeenablestheengineer tooptimizeoverall utility consumption and set process and utility system configurations prior to final detailed simulation and optimization. Thesetechniques are both simpleand practical. This chapter illustrates how the application of Pinch Technology can provide the design engineer with the insight and understanding needed to evaluate complete process system designs.
Processheatand power integrationhasasignificantimpacton theoverallprocessdesign. Therefore,itcannotbeconsidered in isolation. Itmustbe consideredas anintegralpart ofthe system designor "synthesis".Many decompositionschemes have been proposed that break down the design of chemical process systemsintosubsystems,promotinga systematicandstructured approach to synthesis.
One suchdecomposition, schematically representedby Linnhoff in the "onion diagram''(1), Figure 3.1.1, breaks the total process system intofoursubsystems :thereaction system,the separationsystem,the heatexc...
