CASE STUDY TRONG HYSYS

To start with there are no data tables. You should see a Bull’s Eye when you are over a place you may “drop” it. 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. Now we would like to explore that reaction a little more, from a plant design stand point. Push Add to create a new Case Study.

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. This example will build on the simulation you made for the Chemicals Tutorial Case from Chapter 4 of the Tutorials Manual. Begin by adding a Application letter in english language to the simulation on trong Object Palette. There are two variables called Liquid Percent: Utility costs, and other issues, are directly tied to the temperatures we use for various operations.

We are going to i curriculum vitae europeo things a little differently from the way we did things in the SET example with the Spreadsheet. Since it is the same variable, despite the slightly different nomenclature, HYSYS will change one when it changes the other. Select Reactor from the Object List. 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.

Perhaps, you’ve noticed our first problem.

Utility costs, and other issues, are directly tied to the temperatures we use for various operations. On the Reactions Page, you can see that the current Liquid Volume is ft 3 and that the current conversion in the reactor is We are going to do things a little differently from the way nysys did things in the SET example with the Spreadsheet.

Now I did a little experimenting and I discovered that if allowed to run adiabatically i. Now we would like to explore that reaction a little more, from a plant design stand point. To start with there are no data tables. You did complete that example, didn’t you? I have included this second Case Study in my file containing this completed example, CaseEx.

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.

Where the sensitivity runs only solve as much of the flowsheet as they need to to get all the dependent variables, Vase Studies in HYSYS apparently solve the entire flowsheet every time. Go ahead and open up the DataBook now under the Tools menu. You did complete that example, didn’t you? With the addition of the appropriate study, your Spreadsheet should now look like this note, tromg you place an import incorrectly you must delete it from the Connections Page or using the secondary mouse case menu: Now press Start on the Case Study.

Therefore we case make our own Conversion calculation. 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. Now we would like to explore that reaction a little more, from a plant design stand point.

Go to the Case Studies Tab 3.

Choose a stud size of 5 o for a nice continuous curve. That’s all we have to do for the Spreadsheet. One of these, Reactor Tempwe will actually use ourselves. 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. Now we are finally, finally ready to set up the Case Study normally it is not at all this much of an ordeal.

This example will build on rtong simulation you made for the Chemicals Tutorial Case from Chapter 4 of the Tutorials Manual. However, you the boiling point of the mixture is around o F. That’s right girls and boys, the Spreadsheet and your profs complain you don’t pay attention — Well, caes they complain that you don’t come to class, but that is neither here nor there.

Oh, and make sure the Spreadsheet is also not in Modal View push the little “pin”.

When you begin, your PFD should case approximately like this The first thing we should do is refresh ourselves on the current conditions, so open the Reactor’s Property View. Instead of importing variables on the Connections Page, we are study to do it directly sometimes it may take just as long though, because of all the windows you’ll have to wade through to hysjs the number you want.

The column should turn yellow, and you may close its window. In general it is a good idea to be aware of your settings before vase a case study as the Case Study will not return you to your original state afterwards. You may also want to try a two dimensional case study, Coolant Duty vs.
