ABSTRACT
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.
