WebAug 1, 2015 · Conclusion In this work, the techno-economic analysis of biodiesel production by reactive distillation (alkali- catalyzed and heterogeneous-catalyzed processes) was performed using a process simulation approach. The annual production cost and capital expenditure are found to be lower for the heterogeneous catalyzed process. WebDec 9, 2002 · In a reactive distillation column, both the chemical conversion and the distillative separation of the product mixture are carried out simultaneously. Through this integrative strategy, chemical equilibrium limitations can be overcome, higher selectivities can be achieved and heat of reaction can be directly used for distillation.
WebProcess synthesis for reactive distillation includes design and optimisation of the column. Because of the interactions between reaction and distillation in the combined unit, the modelling and design of reactive distillation is complex. WebKen McCarley, P.E.
