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

However, you the boiling point of the mixture is around o F. Choose a step size of 5 o for a nice continuous curve.

Now position your cursor over the 12C3Oxide’s Molar Flow and using the secondary mouse buttondrag the number to cell B2 of the Spreadsheet. Checkmark the reactor temperature and level as independent variables and the convesion as a dependent variable. Push Add to create a new Case Study.

Now press Start on the Case Study. Yep, Conversion is nowhere to be found on that list of Variables. That’s all we have to do for the Spreadsheet. We’re done with the example. About Risman Dukhan Process learning never stops until the end of our life.

Now I did a little experimenting and I discovered that if allowed to run adiabatically i. 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. 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. If you’ve worked with Aspen, you’ve probably done Sensitivity Runs.

Blissfully, unaware that we just made a mistake, let us now proceed to doing something about the Conversion. You are commenting using your WordPress.


On the Worksheet Page, you can see that currently the entire contents of the reactor titorial exiting via Reactor Prods Reactor Vent has zero flow at o F. Switch to the Case Studies Page. We are going to do things a little differently from the way we did things in the SET example with the Spreadsheet.

Case Studies Example

You can check out below: Fill in your details below or yhsys an icon to log in: 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. This entry was posted in Chemical EngineeringEducationEngineeringProcess Technologysimulation-software and tagged design-engineeringHysysProcesssimulation-software.

Select Reactor from the Object List. Post was not sent – check your email addresses! Now we are finally, finally ready to set up the Case Study normally it is not at all this much of an ordeal. You should see a Bull’s Eye when you are over a tutogial you may “drop” it.

By continuing to use this website, you agree to their use. 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. Perhaps, you’ve noticed our first problem.

Pick the Spreadsheet as the Object and B6: In this case, the temperature we set for our reactor determines how much coolant is required hydys has a direct effect on how well the column runs, and of course, it has a critical effect on the reaction itself.

The Variables Navigator will appear. In general it is a good idea to be aware of your settings before running a case study as the Case Study will not return you to your original state afterwards.


For more information on the special functions and logical expressions you tutoriap use, press Function Help With the addition of the appropriate text, your Spreadsheet should now look like this note, if you place an import incorrectly you futorial 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.

Before pushing start and you could at this pointthere is one thing I would point out to you. On the Parameters Page, checkmark the box that says Ignore column during calculations.

You did complete that example, didn’t you? Therefore, that is the variable we truly wanted.

Get Started With Hysys V 7.3

And where do we get to make our own calculations? Hint, hint, wink, wink, nudge, nudge. It’s easy, because the variables are already defined, and it’s informative. You are commenting using your Twitter account.

When you begin, your PFD should look approximately like this. To shorten your simultation time enormously, open the column’s Property View. Email required Address never made public. All right, we’ll worry about that in a second.

It doesn’t actually consider it a variable and heaven forbid you should actually want to use it for something.

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. Sorry, your blog cannot share posts by email. Let’s go ahead and get the Liquid Percent while we are here. You’ll tjtorial need to change the basis from Mole Fractions to Mole Flows.
