This paper will demonstrate the importance of choosing the correct thermodynamic package when using a process simulator to model a distillation column. The authors will present a brief background of how thermodynamics are used in distillation design. The authors will then present a test case comparing operating data and design details of a commercial hydrocarbon column with results from three different process simulation packages. The test case will be used to demonstrate the steps to obtain a good model using a process simulator. Finally, the authors will provide guidelines to select the correct thermodynamic method when using a process simulation package to model a distillation column.
