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.

You may see one, as in my graph, or even two anamalous points. Speaking of which, go ahead and add for that cell the Variable Type: Now we would like to explore that reaction a little more, from a plant design stand point.
By continuing to use this website, you agree to their use. Before pushing start and you could at this pointthere is one thing I would point out to you. This entry was posted in Chemical EngineeringEducationEngineeringProcess Technologysimulation-software and tagged design-engineeringHysysProcesssimulation-software. Never regard study as a duty but as an enviable opportunity to learn to know the liberating influence of beauty yysys the realm of the spirit for your own personal joy and to the profit of the community to which your later works belong.
On the Parameters Page, checkmark the box that says Ignore column during calculations. Email required Address never made public. Oh, and make sure the Spreadsheet is also not in Modal View push the little “pin”. This is the reason that that is not the variable we really wanted to use.
You are commenting using your Twitter account. The multiplier is because we wish to express the conversion as a percentage. Yep, Conversion is nowhere to be found on that list of Variables. Since it is the same variable, despite the slightly different nomenclature, HYSYS will change one when it changes the other. Post was not sent – check your email addresses!
Get Started With Hysys V – Chemical Process Simulation – Community
I have collected some tutorial video for our Learning purpose. If you’ve worked with Aspen, you’ve probably done Sensitivity Runs. The Liquid Percent Level is not offered as an independent variable! Since the general rule goes, the bigger the piece of equipment, the more expensive it is, we’d like to see how sensitive the reaction is to the size of the reactor.
Get Started With Hysys V 7.3
There are two variables called Liquid Percent: The column should turn yellow, and you may close its window.
You did complete that example, didn’t you?
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. Well just in case you didn’t, the example consisted of using a CSTR to react Propylene Oxide with Water to make Propylene Glycol, then separating that out as a product. As you shall see o F is more than sufficient for an upper bound. Blissfully, unaware that we just made a mistake, let us now proceed to doing something about the Conversion.
Choose a step size of 5 o for a nice continuous curve. And where do we get to make our own calculations? Now, in cell B6enter the following equation: Therefore we want our maximum temperature to be less than o F. 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.
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:.
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.
Remember our goal is to vary the reactor temperature and tuotrial size done here by varying what percentage of cubic feet need actually be filled with liquid and observe the effect on the reactor’s efficiency i. Now press Start on the Case Study. You should see a Bull’s Eye when you are over a place you may “drop” it.
You should see a nice, pretty 3 dimensional graph of Conversion vs. Uysys in your details below or click an icon to log in: One of these, Reactor Tempwe will actually use ourselves. Percentageand the Variable Name: Since we will be varying the liquid volume by changing the Liquid Level percentage and we like even numbers, go ahead and change the Vessel Volume to ft 3.
In this case that would mean running an unnecessary column times from the Number of States in the upper right corner. 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 be buggy. 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 critical effect on the reaction itself.
When you are finished, hyzys 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.
When you begin, your PFD should look approximately like this. Utility costs, and other issues, are directly tied to the temperatures we use for various operations.
All right, we’ll worry about that in a second. Go ahead and look at the other pages before you close the Spreadsheet window.
