simulation with each tutorial, it is highly recommended that you save your work emphasize one particular feature of Aspen that is covered in the tutorial for that. with HYSYS, as the starting point for your dynamic tutorial case. some of the basic concepts of building a simulation in HYSYS. Three. I have collected some tutorial video for our Learning purpose. You can 6-Gas Processing – LNG Fractionation Unit with Aspen hysys

Another big issue is Capital Costs. And where do we get to make our own calculations? Therefore we must make our own Conversion calculation.

The first thing we should do is refresh ourselves on the current conditions, so open the Reactor ‘s Property View. You may see one, as in my graph, or even two anamalous points. Before pushing start and you could at this pointthere is one thing I would point out to you. Go ahead and open up the DataBook now under the Tools menu.

Get Started With Hysys V 7.3

There are two variables called Liquid Percent: Switch to the Case Studies Page. I have included this second Case Study in my file containing this completed example, CaseEx. You did complete that example, didn’t you?

When you are finished, the page should look like it does below Note that the conversion, in red because it is a spreadsheet calculated value, is the same as we saw it on the Reactor’s Property View. Now position your cursor over the 12C3Oxide’s Molar Flow and using the secondary mouse buttondrag the number to cell B2 of the Bysys. Where the sensitivity runs only solve as much of the flowsheet as they need to to get all the dependent variables, Case Studies in HYSYS apparently solve tytorial entire flowsheet every time.

You are commenting using your Facebook account. On the Variables Page, you should see three variables already defined. Now, in cell B6enter the following equation: Now press Start on the Case Study. Speaking of which, go ahead and add for that cell the Variable Type: In this case, the temperature we set for our reactor determines how much coolant is required and has a direct effect on how well the column runs, and of course, it has a tuttorial effect on the reaction itself.


We’re done with the example. Conversion as the variable go ahead and change the Variable Description at the bottom tutoria, just Conversion. This site uses cookies. You can check out below: That’s right girls and boys, the Spreadsheet and your profs complain you don’t pay attention — Well, actually they complain that you don’t come to class, but that is neither here nor there.

I have collected some tutorial video for our Learning purpose. Now we are finally, finally ready to set up the Case Study normally it is not at all this much of an ordeal.

With the addition of the appropriate text, your Spreadsheet should now look like this note, if you place an import incorrectly you must delete it from the Connections Page or using the secondary mouse button menu:.

Therefore we want our maximum temperature to be less than o F. The Liquid Percent Level is not offered as an independent variable! In general it is a good idea to be aware of your settings before running a case study as the Case Study will not return you to your original state afterwards. Also, though the manuals state that you should be able to delete individual points, I was unable to do so the Delete key at the bottom of the window erases the whole Case Study, so don’t try that.

Go back to the Case Studies Page actually you might first want to make a recording on the Data Recorder Page, tutoria that is a good habit to get into.

Case Studies Example

Now I did a little experimenting and I discovered that if allowed to run adiabatically i. You’ll probably need to change the basis from Mole Fractions to Mole Flows. We will need two more variables: Fill in your details below or click an icon to log in: Again, I don’t know why, I’m just reporting what I saw and warning you to be aware that the data you get may possibly hysgs buggy. All right, we’ll worry about that in a second. To shorten your simultation time enormously, open the column’s Property View.


As you shall see o F is more than sufficient for an upper bound. For a tjtorial bound on temperature, let us take the first temperature we were given to try in the example, 75 o F. Now make sure the Spreadsheet Property View is on the Spreadsheet Page yes, you’ll need to push the little “pin” on the stream’s window to switch out of Modal View. The column should turn yellow, and you may close its window.

Now immediately, you should see we have a problem executing this plan. Percentageand the Variable Name: We are going to do things a little differently from the way we did things in the SET example with the Spreadsheet. Later, I would come back and it would work just fine from then on, but I recommend saving your work before ever trying that, just in case. You are commenting using your Twitter account. Go ahead and look at the other pages hyzys you close the Spreadsheet window.

About Risman Dukhan Hhysys learning never stops until the end of our life. You should see a nice, pretty 3 dimensional graph of Conversion vs. Yep, Conversion is nowhere to be found on that list of Variables.

I recommend that you now look at the results and try to analyze why they came out as they did and play with the various 3D graph controls use the secondary mouse button over the graph to bring up the menu. One of these, Reactor Tempwe will actually use ourselves.
