This is simple course on Plant Simulation via Aspen HYSYS will show you how to:

  • Set a fluid package
  • Manipulate a Flowsheet
  • Add unit operations
  • Input all the minimum required data.

This is helpful for students, teachers, engineers and researchers in the area of R&D and Plant Design/Operation.

The course is didactic, with the minimum theory required to work on the Simulation Case (hands-on-workshop)!

What is a Process Simulation?

Simulation help engineers to model processes faster, easier and without losing considerable amount of resources such as money and time.

It helps to cover different scenarios in order to optimise existing processes or to design new ones.

It helps process engineer to understand current operation conditions as well.

6
Meet our Chemical Process!

This will be our process! Please ensure to get to know it. The better you know your process (overall) the easier it becomes to simulate it.

Try to remember all unit operations, streams and important flow rates, given data and variables.

Good luck!

7
Opening Aspen HYSYS (New Case, Save, Open, Templates)

How to start a new simulation, new case, save case, templates and so on...

8
Adding a Component List

Selecting and filling up the component list. All reactants, products, intermediates must be present.

9
Choosing a Fluid Package

Selection of a good Fluid Package. Avoid components which are not well modeled with the selected fluid package. Method Assistant is very useful here!

10
Setting up Reactions

If there is any reactor, a set of chemical reaction will be required. Remember that a "Set" of reactions requires at least 1 "Reaction". Ensure to use -1 for reactants and +1 for products.

11
What is a Flowsheet?

What is a flowsheet, and how to use it.

Why do we need a flowhseet?

12
Manipulation of the Flowsheet

Manipulation of the Flowsheet:

  • Adding Unit Operations
  • Adding Material and Energy streams
  • Moving
  • Labeling
  • Rotating
  • Deleting
  • Copy and Pasting
13
The Model Palette

The model palette and how to use it. Which unit operations are present.

14
Cooler (Chiller)

Modeling a Chiller, with an inlet/outlet of material stream. A heat/energy stream is required to set up this unit operation.

15
Flash Drum

Choose the "Separator" in order to simply make a flash separation. Liquid and Vapor separate due to the equilibrium condition.

16
Heater

The heater is modeled similar to the chiller, there is an inlet and outlet of material. We must add an Energy Stream in order to set the Heat Duty

17
Equilibrium Reactor

Setting up a Reactor. It is based on the activity/gibbs free energy/equilibrium constant.

18
Expander

A turbine can be modeled with an expander. It takes out energy via transformation of internal energy to mechanical energy

19
Valve

The valve is used to decrease pressure or decrease flow rate.

20
Setting up a Distillation Column

How to set up the distillation column in 5 simple steps

21
Pump

The pump is used to move liquids or increase pressure in liquids

22
Getting Workbook Tables

Creating and opening the Workbook. It will present all relevant data on unit operations, streams and compositions.

23
Exporting Data

How to export the results, specially those of the workbook to excel (spreadsheet)

24
Analysis and Conclusion

A small analysis on the simulation results. Verifying the final process. Some final recommendations

25
Downloading the Results, Workbook and Simulation Case

You need the simulation? Or maybe the workbook? Or also the excel spreadsheet? Get this downloaded here!

26
Course Review and Wrap-up

Final conclusions on the course, warping-up the course!

You can view and review the lecture materials indefinitely, like an on-demand channel.
Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
