Optimal design of hybrid distillation-membrane processes based on a superstructure approach

Considerable effort is currently being put towards process intensification to design more sustainable and energy-efficient processes. Hybrid distillation-membrane processes are prime examples of such intensified In this work, different strategies presented for how handle the complexity membrane network hybrid in terms initialisation convergence simulation optimisation. A superstructure approach optimisation networks within verified. The energy consumption economic performance a distillation-pervaporation process, as well that corresponding extractive distillation separate minimum-boiling azeotropic mixture compared feed compositions. impact properties cost also briefly considered. results show total heat duty always lower than system considered, confirming efficient. annualised cost, however, found be economically attractive at compositions, while preferred higher
