  1. different set of binary coefficient (nrtl) hysys

    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
