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.

It doesn’t actually consider it a variable and heaven forbid you should actually want to use it for something. This site uses cookies. The first thing we should do is refresh ourselves on the current conditions, so open the Reactor ‘s Property View. Therefore ttorial must make our own Conversion calculation. Let’s go ahead and get the Liquid Percent while we are here. Select Reactor from the Object List.

You should see a Bull’s Eye when you are over a place you may “drop” it. Even though the vent is nominally empty, we need to include it on the off chance that some of the reactor contents do become vapourized. We’re done with the example. 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.

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. It’s easy, because the variables are already defined, and it’s informative.

Pick the Tutorjal as the Object and B6: Never regard study as a duty but as hyshs 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. Switch to the Case Studies Page. Email required Address never made public. However, you the boiling point of the mixture is around o F.

On the Parameters Page, checkmark the box that says Ignore column during calculations.

This is the reason that that is not the variable we really wanted to use. Again, I don’t know why, I’m just reporting what I saw and warning you to be aware tutoria, the data you get may possibly be buggy.

Conversion as the variable go ahead and change the Variable Description at the bottom to just Conversion. That’s all we have to do for the Spreadsheet. You may also want to try a two dimensional case study, Coolant Duty vs. Perhaps, you’ve noticed our first problem.

Speaking of which, go ahead and add for that tuutorial the Variable Type: Now we would like to explore that reaction a little more, from a plant design stand point. Since it is the same variable, despite the slightly different nomenclature, HYSYS will change one when it changes the other. You are commenting using your WordPress.

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. 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 the entire flowsheet every time.

To shorten your simultation time enormously, open tutorrial column’s Property View. All right, we’ll worry about that in a second. Go ahead and open up the DataBook now under the Tools menu. You should see a nice, pretty 3 dimensional graph of Conversion vs. 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.

Go back to the Case Studies Page actually you might first want to make a recording on the Data Recorder Page, as that is a good habit to get into. Now we could plug about different combinations of temperature and size in by hand, but what would be the point when HYSYS has so thoughtfully provided us with a tool to do just that.

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:. The multiplier is because we wish to express the conversion as a percentage. 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. You did complete that example, didn’t you?

You are commenting using your Facebook account. One of these, Reactor Tempwe will actually use ourselves. Push Add to create a new Case Study.

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. By continuing to use this website, you agree to their use. Go ahead and look at the other pages before you close the Spreadsheet window.

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. Before pushing start and you could at this pointthere is one thing I would point out to you.

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. Now we are finally, finally ready to set up the Case Study normally it is not at all this much of an ordeal.

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. Start by opening up the file you made from the Tutorial. 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. The Variables Navigator will appear.

Another big issue is Capital Costs.
