Abstract : Distillation units require huge amounts of energy for the separation of the multicomponent mixturesinvolved in refineries and petrochemical industries. The overall efficiency of the distillation column systemis determined from the trade-offs of the Operating Expenditures OPEX and Capital investmentcost CAPEX, as there is a strong interaction between the distillation columns and the Heat ExchangerNetwork HEN of the interconnecting streams. In this paper, a systematic Mixed Integer Non-LinearProgramming MINLP optimization methodology for process integration of distillation column complexis presented. The highly nonlinear rigorous models of the distillation column and phase change are beingsubstituted with simple surrogate models that generate operating responses with adequate accuracy.The methodology is applied on two case studies of the aromatics separation PARAMAX complex. Theresults illustrate significant reductions on the Total Annualized Cost. With a scope limited to the benzeneand toluene columns, the gain reaches about 15%.
