Simultaneous heat integration and parameteroptimization for thermally coupled complexdistillation flowsheet

摘要

This paper addresses the problem of simultaneous heat integrationand parameter optimization for a given complex distillation column flowsheet.A general design procedure including converting a complex distillation columnflowsheet into its thermodynamic equivalent simple column sequence, theshortcut design of the equivalent sequence, and heat integration structuregeneration with pinch design method is developed. The example demonstratedthat the design procedure can give effectively all the needed design parametersand heat integration structure.
