A thermodynamic approach to multicomponent distillation system synthesis

This paper shows a synthesis method of multicomponent distillation systems with heat integration based on the available energy concept. With this method, the problem of synthesizing the heat integrated distillation systems in which there are heat source and sink streams supplied from other processes can be solved so as to minimize the process utilities. Moreover, since the system synthesis is executed in the (1 – T0/T) vs. Q diagram, it is possible to visibly represent the physical meanings of the computing process.
