Synthesis thermally coupled columns

Synthesis of Partially Thermally Coupled Column Configurations for Multicomponent Distillations... 

The synthesis of partially thermally coupled column configurations for a multicomponent distillation has b n studied in the context of the thermodynamic equivalent structures. There has been formulated a conqtlete space of the possible thermodynamic equivalent alternatives of the partially coupled (PC) configurations for multicomponent mixtures. A formula is presented to calculate the number of all the partially coupled schemes for any n-conqx)nent mixture. The formulated alternatives of all the possible arrangements of PC configurations provide a complete subspace for optimal design of multicomponent distillation systems not only for the economics, but also for column equipment designs.
