Dimensioning a Distillation Column for Separation of Water and Ethanol

Application ID: 56071


This example shows how to make a simple model for a binary distillation process. A thermodynamics property package, available in the Chemical Reaction Engineering Module, is created to study the separation of a nonideal mixture of ethanol and water. The required equilibrium relationship is generated using the Equilibrium Calculation functionality available when using the thermodynamics features. The model is used to find the optimal design of the column, in terms of the length of the stripping and rectifying sections, to meet a set of specified distillate and bottoms compositions.
