HYSYS Tutorials

A HYSYS TutorialsThe Tutorials section of this manual presents you with independent tutorial sessions. Each of these tutorials guide you step-by-step through the complete construction of a HYSYS simulation. The tutorial(s) you choose to work through will likely depend on the simulation topic that is most closely related to your work, your familiarity with HYSYS and the types of simulation cases you anticipate on creating in the future.All completed Tutorial cases are included with your HYSYS package, and are available on HYSYS\Samples.

Regardless of which tutorial you work through first, you will gain the same basic understanding of the steps and tools used to build a HYSYS simulation. After building one of these tutorial cases, you might choose to build one or several more, or begin creating your own simulations.If you are new to HYSYS, it is recommended that you begin with the steady state tutorials. These tutorials explicitly detail each step required to complete the simulation. In steps where more than one method is available to complete a particular action, all methods are outlined. The dynamic tutorials (which are continued after the steady state section) are also presented in a step-by-step manner, but are less detailed in their explanations. They assume a rudimentary knowledge of the HYSYS interface and methods.

The three tutorials are classified according to three general areas of interest: 1. 2. 3. Gas Processing Refining Chemicals

Each area has an associated steady state and dynamic tutorial. The dynamic tutorials use the steady state cases and add control schemes and dynamic specifications required to run the case in Dynamic mode. If you are only interested in steady state simulation, go through the steady state tutorial(s) that most interest you and stop at the dynamics section. However, you may be strictly interested in learning to apply dynamic simulation methods and do not want to go through building

the steady state simulation. In this situation, simply use the pre-built steady state base case, included with HYSYS, as the starting point for your dynamic tutorial case.
