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 can check out below: Another big issue is Capital Costs. Now position your cursor over the 12C3Oxide’s Molar Flow and using the secondary mouse buttondrag the number to cell B2 of the Spreadsheet. Pick the Spreadsheet as the Object and B6: For a lower bound on temperature, let us take the first temperature we were given to try in the example, 75 o F. You should see a Bull’s Eye when you are over a place you may “drop” it.

I have included this second Case Study in my file containing this completed example, CaseEx. Fill in your details below or click an icon to log in: 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.
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. Perhaps, you might want to develop the habit of always making a record in the Data Recorder also part of the DataBook right before running your Case Studies.
Remember our goal is to vary the reactor temperature and reactor 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.
As you shall see o F is more than sufficient for an upper bound. 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:. In this case that would mean running an unnecessary column times from the Number of States in the upper right corner. To shorten your simultation time enormously, open the column’s Property View.
However, you the boiling point of the mixture is around o F. 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. 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.
You are commenting using your Facebook account. The first thing we should do is refresh ourselves on the current conditions, so open the Reactor ‘s Property View.
Yep, Conversion is nowhere to be found on that list of Variables. Percentageand the Variable Name: Notify me of new comments via email. This means that if you went so far as to run with no coolant, you would lose product out the vent never a good thing.
Case Studies Example
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. Now immediately, you should see we have a problem executing this plan. Before pushing start and you could at this pointthere is one thing I would point out to you. 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.
You are commenting using your Twitter account. 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. We will need two more variables: Conversion as the variable go ahead and change the Variable Description at the bottom to just Conversion.
Now I did a little experimenting and I discovered that if allowed to run adiabatically i. Hint, hint, wink, wink, nudge, nudge.
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. Go back to the Case Studies Ttutorial actually you might first want to make a recording on the Data Recorder Page, as that is a good habit to get into.
One of these, Reactor Tempwe will actually use ourselves. Oh, and make sure the Spreadsheet is also not in Modal View push the little “pin”. Nysys we need the Molar Flowrate of Propylene Oxide entering the reactor. This example will build on the simulation you made for the Chemicals Tutorial Case from Chapter 4 of the Tutorials Manual. Choose a step size of 5 o for a nice continuous curve.
We’re done with the example. Where the sensitivity runs only solve as much of the flowsheet as tktorial need to to get all the dependent tuforial, Case Studies in HYSYS apparently solve the entire flowsheet every time. On the Parameters Page, checkmark the box that says Ignore column during calculations. You may see one, as in my graph, or even two anamalous points.
We are going to do things a little differently from the way we did things in the SET example with the Spreadsheet. Utility costs, and other issues, are directly tied to the temperatures we use for various operations.
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 hysyd you want. Now press Start on the Case Study.
Get Started With Hysys V 7.3
You should see a nice, pretty 3 dimensional graph of Conversion vs. That’s all we have to do for the Spreadsheet. If you’ve worked with Aspen, you’ve probably done Sensitivity Runs.
