(631k) Modeling of Batch Distillation for Scale-up

Modeling a batch distillation before scaling up can provide useful insight to the time and materials required to reach the desired end point.  Commercially available software offers models that have already been developed and simply require the user to enter parameters specific to their equipment and process streams.  We present several distillation models developed in DynoChem using activity coefficients from different thermodynamic models.  We discuss the accuracy of these models on the kilo-scale through multiple successful applications.  We also demonstrate the regression of NRTL parameters for a binary solvent system with the presence of a dissolved, non-volatile component.
