The influence of the estimated values of the phys. constants and vapor pressure of esters in a process simulation using the Aspen Hysys was evaluated from the energy parameters of a methanol/ethanol recovery distillation column of a biodiesel production plant. This study was necessary, because in process simulators most of FAMEs and FAEEs are not originally available in the simulator library, due to the lack of exptl. data for these components. Accuracy analyses for the values of reboiler temperature and reboiler heat duty of the simulated column were performed from simulations using different predictive models and exptl. data. Results demonstrated that small deviations of the vapor pressure can generate considerable errors in the reboiler temperature and reboiler heat duty. In addition, errors can be even greater if vapor pressure is estimated from inaccurate critical constants Deviations up to 13% were observed for the reboiler temperature and up to 16% for the reboiler heat duty. Reliable simulations and process design are strongly dependent on the selected phys. properties of the esters, specially vapor pressure, which are generated from available exptl. data and using group contribution and corresponding states models.
