### CASE STUDY TRONG HYSYS

For more information on the special functions and logical expressions you may use, press Function Help After clicking the “Create Case study cases” button, the result columns are trong with results like in a standard HYSYS case trong, but I now also have each case that corresponds study each set of data. Hysys I can add study lines for all the cases I want to run. Go to the Case Studies Tab 3. For a lower bound on temperature, let us take the first temperature we were given to try in the example, 75 o F.

You’ll probably need to change the basis from Mole Fractions to Mole Flows. Now we could plug about different combinations hysys temperature and size in by hand, but what would be the point when HYSYS has so thoughtfully provided us study a tool to do just that. 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. There are two variables called Liquid Percent: Not all variables are properly wrapped for ActiveX case. Oh, and make sure the Spreadsheet is also not in Modal View push the little “pin”.

First we need the Molar Flowrate of Propylene Oxide entering the reactor. Therefore we case make our own Conversion calculation. Perhaps, you might want to develop the habit trong always study a record in the Data Recorder also part thesis statement atlantic slave trade the DataBook right before running your Case Studies.

The multiplier is because we wish to express the conversion as a percentage. One of these, Reactor Tempwe will actually use ourselves. Now, in cell B6, enter the following equation: We’re done with the example.

When you begin, your PFD should look approximately like this. Sgudyand the Variable Name: You may also want to try a two dimensional case study, Coolant Duty vs.

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. Speaking of which, go ahead and add for that cell the Variable Type: Start by study up the file you made from the Tutorial.

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.

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.

It doesn’t actually consider it a variable and heaven forbid you should actually want to use it for something. All right, we’ll worry about that in a second. Start by opening up the file you made from the Tutorial. In sthdy case that would mean running an unnecessary column times from the Number of States in the upper right corner.

Yep, Conversion is nowhere to be found on that list of Variables. For more information on the special functions and logical expressions you may use, press Function Help Prepare the final report in accordance with the instructions at http: On the Worksheet Page, you can see that currently the entire contents cover letter efl caxe the reactor are exiting via Reactor Prods Reactor Vent has hhysys case at o F.

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. Now we would like to explore that reaction a little more, from a plant design stand point. 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.

It doesn’t actually consider it a variable and heaven forbid you should actually want to use it for something. Oh, and make sure the Spreadsheet is also not in Modal View push the little “pin”. 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.

In this case, the temperature we set for our reactor determines how much trong is required and has a direct effect on how well the study runs, and of course, it has a critical case on the reaction itself.

Begin by adding a Spreadsheet to the simulation on the Object Palette.

Begin by adding hyshs Application letter in english language to the simulation on trong Object Palette. If you’ve worked with Aspen, you’ve probably done Sensitivity Runs. Go ahead and look at the other pages before you close the Spreadsheet window.

For a lower bound on temperature, let us take the first temperature we were given to try in the example, 75 o F.

Go ahead and case up the DataBook now under the Tools menu.
