i'm working on dynamic simulation of batch distillation in hysys!!!
in my system there are three components
1 ethylacetate
2 water
3 isopropanol
during the simulation there are two liquid phase in the reflux accumulator (the components at 102 kpa and 70 °C determines liquid-liquid equilibrium)
i would use a different set of binary coefficient (NRTL model) for diffrent equipments. The accumulator, reboiler and other equipments are in different environment from the column.
how can i fix a set of binary coefficient for the only accumulator (coefficient from the liquid -liquid equilibrium data regression) and another for the reboiler , column and remaining equipments (from the liquid vapor equilibrium data regression )?????
i attached a file in which there is my simulation!!!!!!
thanks in advance
best regards
p.s. sorry for my english
