HYSYS

The purpose of this web site is to introduce the use of HYSYS as a modeling and analysis tool in the Unit Operations Laboratory of the chemical engineering program. HYSYS can help the students perform lengthy calculations in a manner of a few seconds. Hence, students can make parametric analysis and other evaluations with ease and can provide a more in depth analysis of the performance of unit operations in the laboratory.

HYSYS will help the students to predict any variables dependent by varying any other variables chosen by the student. For example a student will be able to predict the overhead and bottom stream conditions of a distillation column given the feed rate and the load on the reboiler. Alternately the student can obtain the feed conditions by specifying either the overhead or the bottom conditions, or get the reboiler load by specifying the feed and the overhead’s conditions. 

In HYSYS, provided that the environment is properly set up, the above operations can be performed by just choosing a few options in the menu. This web site provides guides to lead students through the steps to using HYSYS.

Getting Started  

A brief introduction to HYSYS and instructions for stating up the HYSYS program.

HYSYS Distillation Tutorial

The HYSYS Distillation Tutorial describes how to model the UF Unit Operations Laboratory distillation columns. Two case studies are included to illustration the use of HYSYS for both continuous operations. The transient conditions for continuous distillation startup and batch operations are modeled.

Unit Operation Examples

Models of equipment in the Unit Operations Laboratory.  Use these models as templates - the parameters and specifications have purposely been distorted. While the parameters in the models work for simulation demonstrations, the values are not correct for the equipment in the laboratory.  Review the specifications for the equipment that you are using and input your own parameter values.

HYSYS Cases 

Several examples provided by Hyprotech are included.  Read the HYSYS.PLANT manual for details about these models.  The Cases directory in the installed code includes many other cases and tutorials that can be useful in looking for examples of how to simulate processes.
