Abstract: This work applied a process design methodology based on the combined use of process simulation and heat integration with pinch analysis to analyse a PV-integrated hybrid process for ETBE production. Mathematical modelling and simulation of the membrane module have been performed using Aspen Custom Modeler and linked with Aspen Plus software to describe the overall process. Simulation results showed that the hybrid process, in which the PV modules are located on a side-stream withdrawn from the distillation column, is more favourable in energy consumption and it shows lower content of ethanol in distillate stream than other membrane integrated hybrid processes. Heat integration with pinch analysis shows that it is possible to achieve savings of up to 18% in utilities consumption.
