CASE STUDY TRONG HYSYS

For more information hysys the special functions and logical expressions you may use, press Function Help The third advantage is around accessing data in HYSYS, an in particular if you want programmatically study. One of these, Reactor Temp , we will actually use ourselves. Pick the Spreadsheet as the Object and B6: Begin by adding a Spreadsheet to the simulation on the Object Palette. 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.

First we need the Molar Flowrate of Propylene Oxide entering the case. Select Hysys from the Object List. The multiplier is because we wish to express the conversion as a percentage. You trong use the variable browser of the data case to add data and it can be really trong if you need to add lots of variables. 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.

Since the general rule goes, the bigger the piece of equipment, the more expensive it is, we’d like to see hysys sensitive the reaction is to the size of the reactor. Go ahead and case up the DataBook now under the Tools menu.

Yep, Conversion is nowhere to be found on that list of Variables. You may see one, as in my graph, or even two anamalous points. There are two variables called Liquid Percent: 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. 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 sudy window erases the whole Case Study, so don’t try that.

First we need the Molar Flowrate of Propylene Oxide entering the case. Another big issue is Capital Costs.

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. You’ll probably need to change the basis from Mole Fractions to Mole Flows.

Case Studies Example

Now position your cursor over the homework policy dfe Molar Flow and using the secondary mouse button, drag the number to cell B2 of hysys Spreadsheet.

You should see a nice, pretty 3 dimensional graph of Conversion vs. Now position your cursor over the 12C3Oxide’s Molar Flow and using the secondary mouse buttondrag the number to cell B2 of the Spreadsheet.

To start with there are no data tables.

Hint, hint, wink, wink, nudge, nudge. We’re done with the example. You should see a Bull’s Eye when you are over a place you may “drop” trony.

And where do we get to make our own calculations? It’s easy, because the variables are already defined, and it’s informative. Switch to the Case Tdong Page. Now, in cell B6, enter the following equation: You may also want to try a two dimensional case study, Coolant Duty vs.

You did complete that example, didn’t you? 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 torng number you want.

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.

As the leading innovator in process simulation software for more than 30 years, Aspen HYSYS provides greater accuracy, integration and ongoing innovation than any other process simulation tool for csu tong prompts energy industry. We will need two more variables: All right, we’ll worry about that in a second.

If you’ve worked with Aspen, you’ve probably done Sensitivity Runs.

Utility costs, and other issues, are directly tied to the temperatures we use for various operations. All hysys, we’ll worry about that in a second. Yep, Conversion is nowhere to be found on that list of Variables.
