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.

Get Started With Hysys V – Chemical Process Simulation – Community
Choose a step size of 5 o for a nice continuous curve. By continuing to use this website, you agree to their use. Now immediately, you should see we have a problem executing this plan.
For a lower bound on temperature, let us take the first temperature we were given to try in the example, 75 o F. There are gutorial variables called Liquid Percent: 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.
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. Select Reactor from the Object List. Hint, hint, wink, wink, nudge, nudge. Go back to the Case Studies Page actually you might first want to hhsys a recording on the Data Recorder Page, as that tutoroal a good habit to get into.
We will need two more variables: Now press Start on the Case Study. All right, we’ll worry about that in a second.
Case Studies Example
This is the reason that that is not the variable we really wanted to use. 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.
Never regard study as a tutofial but as an enviable opportunity to learn to know the liberating influence of beauty in the realm of the spirit for your own personal joy and to the profit of the community to which your later works belong.
You are commenting using your Facebook account. 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. Begin by adding a Spreadsheet to the simulation on the Object Palette. Tutorixl, your blog cannot share posts by email. You did complete that example, didn’t you?
You should see a nice, pretty 3 dimensional graph of Conversion vs. You are commenting gutorial your WordPress. You’ll probably need to change the basis from Mole Fractions to Mole Flows. We are going to do things a little differently from the way we did things in the SET example with the Spreadsheet. Another big issue is Capital Costs. Now we are finally, finally ready to set up the Case Ttorial normally it is not at all this much of an ordeal.
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! You are commenting using your Twitter account. Yep, Conversion is nowhere to be found on that list of Variables. If you do not have such a file you may start from my version entitled ChemicalsEx.
Blissfully, unaware that we just tutoriql a mistake, let us now proceed to doing something about the Conversion. Fill in your details hyssys or click an icon to log in: Instead of importing variables on the Connections Page, we are going to do it directly sometimes it may take just as long though, because of all the windows you’ll have to wade through to display the number tutoriap want.
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.
First we need the Molar Flowrate of Propylene Oxide entering the reactor. Checkmark the reactor temperature and level as independent variables and the convesion as a dependent variable. When you begin, your PFD should look approximately like this. Therefore, that is the variable we truly wanted. You should see a Bull’s Eye when you are over a .73 you may “drop” it.
The Variables Navigator will appear. Conversion as the variable go ahead and change the Variable Description at the bottom to just Conversion. You may also want to try a two dimensional case study, Coolant Duty vs. We’re done with the example.
Get Started With Hysys V 7.3
I have included this second Case Study in my file containing this completed example, CaseEx. Perhaps, you’ve noticed our first problem. Utility costs, and other issues, are directly tied to the temperatures we use for tktorial operations.
I have collected some husys video for our Learning purpose. 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 .73 solve the entire flowsheet every time. On the Worksheet Page, you can see that currently the entire contents of the reactor are exiting via Reactor Prods Reactor Vent has zero flow at o F.
If you’ve worked with Aspen, you’ve probably done Sensitivity Runs. For more information on the special functions and logical expressions you may use, press Function Help
