Session 1: Introduction

In this session you get familiar with the environment of Aspen Hysys, Properties, how to add a component, how to select a fluid package, and finally enter simulation environment from which onwards, the instructor provides an example to show how fast Aspen Hysys can solve our thermodynamic-related problems.

Session 2: Fluid package selection

In this session, the instructor shows in a very plain manner how wrong selection of a fluid package can impact calculated physical and thermodynamic properties in Aspen Hysys.

Session 3: Separator simulation

In this session he provides two examples through which you will learn:

  1. how separators could be simulated in Aspen Hysys
  2. What Adjust in Aspen is and how it could be manipulated to ease our calculations.
  3. How to get/print a report like vessel datasheets from Aspen Hysys.

Pressure Change Equipment Simulation

Session 4: Pumps simulation

In this session he provides two examples. In first example he simulates the pump using inlet and outlet conditions while in second example he uses the characteristic curve to calculate the required electricity.

Session 5: Compressor simulation

In this session an air compressor is simulated and its demanded duty is calculated.

Session 6: Turbine simulation

In this session it is shown which pages should be checked and which data should be provided so that Aspen Hysys can calculate the electricity produced by a gas turbine.

Session 7: Line Sizing

Session 8: Control valve simulation

In this session, the instructor talks about his practical experience with Aspen Hysys and how he used Aspen Hysys to verify his manual calculation about flashing in control valves. The control valve reduces a high-pressure condensate to low pressure condensate to be re-used in a deaerator.

Heat exchangers and Air coolers simulation

Session 9: Simple heater

In this session he shows how to set-up a simple heat exchanger and be able to use the software to calculate the duty required.

Session 10: Shell and tube heat exchanger

The session which is the follow-up of first session, shows how exact the flowrate of cooling water could be calculated using Adjust in Aspen Hysys.

Session 11: Air coolers

In this session, he shows how air-cooled heat exchangers pages could be set-up and which information should be provided. In the example it is shown how one fan is enough to cool down distillation column bottom water from 149C to 65C.

Reactions and Reactors Simulation

Session 12: Conversion reactor simulation

To show how to create a reaction set and subsequently to set up a conversion reactor in flowsheet, he uses ATR technology used in methanol, ammonia and hydrogen plants. By using such simulation, he shows how to calculate the flow heat and burner temperatures.

Session 13: Equilibrium reactor simulation

For this session, he shows how fired heaters could be set-up using equilibrium reactor and reactions. To be able to set-up such reactor he teaches how K versus T table could be provided so that the reactor could be run. Also, he instructs how some tools such as Set in Aspen Hysys could be useful when we have one parameter depending on other parameters.

Session 14: Gibbs reactor simulation

Regarding the previous example, this time he simulates the reformer (fired heater) by basing calculation on Gibbs Energy and compares the results with the previous example result.

Session 15: PFR reactor simulation

In this session he shows which sheets and how it should be filled; he simulates the PFR for two scenarios one being oversized PFR and another being optimized sized PFR. Throughout the scenarios he shows how changes for temperature and composition over the length of the reactor could be plotted.

Distillation Column Simulation

Session 16: Distillation column using short-cut approach

To estimate number of actual trays and reflux ratio he uses short-cut column with minimum information.

Session 17: Distillation column using rigorous approach

The session is the follow-up of last session, through which he shows how rigorous model can be set-up. To help the learners better get on top of the rigorous model, he defines different sets of specs and compares their results. Out of these follow-up sessions, reboiler and condenser duties, tray numbers, reflux ratio, overhead and bottom temperatures, compositions and flowrates are calculated.

Session18: Absorber simulation

In this session how CO2 is removed from a gas stream using a packed column and propylene carbonate as pure solvent.



Sizing Part

In this part you will gain good understanding of the followings:

Session 19: Line Sizing

In an example you are taught how by setting criteria, Aspen Hysys can easily and simply calculate the size of the gas or liquid line. In this session it is shown how Hysys calculation is much quicker than the Sizing Excelsheet calculation in which minimum three trials should be carried to find the suitable size for that pipe segment.

Session 20: Control Valve Sizing

In an example-based session, you are taught how to determine valve operating characteristic and how to deal with sizing condition and sizing methods. Upon selection of Fisher as vapor flow model, the presenter calculates CV in Hysys; to validate his result, he also performs the sizing in FSM software by Fisher and compare results calculated in both software.

Session 21: Separators sizing

In this session the speaker shows how quick-sizing method in Aspen Hysys could be used to estimate the dimention but later he compares the result with the result calculated in the rigerous mode in which he polishes the default assumptions in Aspen Hysys. Finally he compares the rigerous mode result with excelsheet and licensor results and shows how  very similar they are.

Session 22: Distillation Column Sizing

Answer the following questions to help you take the course or not.

1.Do you know how to select fluid package for different applications?

2.Do you know how to set-up short-cut column and use its result to model columns in rigorous mode?

3.Do you know how to set-up equilibrium reaction and reactor?

4.Do you know how to use Adjust and Set tools in Aspen Hysys?

5.Do you know how to simulate a pump using characteristic curve and thus calculate the electricity required?

6.Do you know how to simulate a separator and get its datasheet from Aspen Hysys?

Be honest with yourself and for each question give yourself a score out of 10. If the sum is less than 30, then take the course; if the score is between 30 to 50, consult with us. If it is more than 50, we think you don’t need to take it.
