Experimental Validation of Distillation Column Simulations

By Glenn Graham, Pratik Pednekar and Don Bunning |

A practical look at the need for validation, as well as conceptual considerations and a case study This article addresses the need for experimental validation of computer-generated distillation column simulations , and discusses the main concepts involved with experimental validation. Also included is a case study of a simulation effort that initially yielded some uncertainties. These uncertainties were readily resolved with batch laboratory testing.   Difficulties Potential problems with physical property models. Process simulation tools, such as Aspen Plus, CHEMCAD, and ProSim Plus, are indispensable for the design and optimization of separation schemes involving distillation columns. However, the accuracy of their predictions depends highly on the physical property models used in the simulation, and it is not unusual to obtain significantly different simulation results when using different physical property models. Some level of experimental testing is often necessary to validate the simulation results. The physical property models consist of pure component properties, thermodynamic equations and component-interaction parameters used within the thermodynamic equations. Accurate values for the pure component properties and…
