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

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 you want. Go ahead and open up the DataBook now under the Tools menu.
Leave a Reply Cancel reply Enter your comment here This example will build on the simulation you made for the Hysyz Tutorial Case from Chapter 4 of the Tutorials Manual.
Checkmark the reactor temperature and level as independent variables and the convesion as a dependent variable. Now immediately, tutoriall should see we have a problem executing this plan. You may also want to try a two dimensional case study, Coolant Duty vs.
By continuing to use this website, you agree to their use. On the Variables Page, you should see three variables already defined.
Get Started With Hysys V – Chemical Process Simulation – Community
You are commenting using your Twitter account. Post was not sent – check your email addresses! 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.
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. That’s all we have to do for the Spreadsheet. Another big issue is Capital Costs.
Begin by adding a Spreadsheet to the simulation on the Object Palette. In this case, hutorial 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.
Get Started With Hysys V 7.3
You did complete that example, didn’t you? Before pushing start and you could at this pointthere is one thing I would point out to you. If you do not have such a file you may start from my version entitled ChemicalsEx. As you shall see o F is more than sufficient for an upper bound.
Also, though the manuals state that you should be able 7.33 delete individual points, I was unable to do so the Delete key at hysts bottom of the window erases the whole Case Study, so don’t try that. In this case that would mean running an tutorixl column times from the Number of States in the upper right corner.
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. You should see a Bull’s Eye when you are over a place you may “drop” it.
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:.
Go ahead and look at the other pages before you close the Spreadsheet window. One of these, Reactor Tempwe will actually use ourselves. Fill in your details below or click an icon to log in: 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.
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.
Case Studies Example
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.
On the Parameters Page, checkmark the box that says Ignore column during calculations.
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. Oh, and make sure the Spreadsheet is also hysy in Modal View push the little “pin”.
Choose a step size of 5 o for a nice continuous curve.
