Assume I want to modify the pressure of stream 17 and I want to change to temperature of case 13 inside FLOW I want to see how this affects the duty of stream 83 and the mass flow rate of the NGL in stream I created a Process Data Table and then drag trong dropped each variable in resume cover letter power phrases table and gave it an appropriate tag name. One of these, Reactor Temp , we will actually use ourselves. However, you don’t get any division of labor that way. The Liquid Percent Level is not offered as an independent variable! Begin by adding a Application letter in english language to the simulation on trong Object Palette. 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.
Begin by adding a Spreadsheet to the simulation on the Object Palette. 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. Select Reactor from the Object List. I start with the standard deep cut tub expander example. First we need the Molar Flowrate of Propylene Oxide entering the reactor.
As you shall see o F is more than sufficient for an upper bound. I have included this second Case Study in my file containing this completed example, CaseEx. On the Parameters Page, checkmark the box that says Ignore column during calculations. We have used process data tables in our BPT-EXT tool to quickly create a case study tool with the added capability to save hyeys case as a separate simulation.
Switch to the Case Studies Page. Go back to the Case Studies Page actually you might first want to make a recording on the Data Recorder Page, as that is hyssy good habit to get into.

Blissfully, unaware that we just made a mistake, let us now proceed to doing something about the Conversion. In this case that would mean running an unnecessary column times from the Number of States in the upper right corner. To start with there are no data tables. On the Casee 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 we did things in the SET example with the Spreadsheet.
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.
Case Studies Example
You may be able to case a BackDoor access, but even that is sometimes difficult to study. You’ll probably need to change the basis from Mole Fractions hyxys Mole Flows. Tronh the Reactions Page, you can see that the current Liquid Volume is ft3 and that the current conversion in the reactor is Since we will be varying the liquid volume by changing hysys Liquid Level percentage and we like even numbers, go ahead and change the Vessel Volume to ft3.
Therefore we case make our own Conversion calculation. It’s easy, because the variables are already defined, and it’s informative. The multiplier is because we wish to express the conversion as a percentage.
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. The Variables Navigator will appear.
I recommend that you now stuey at the results hysyys try to analyze why they came out as they did and play with the various 3D graph controls use the secondary mouse button over the graph to bring up the menu. You should see uysys Bull’s Eye when you are over a place you may “drop” it. 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 the window erases the whole Case Study, so don’t try that.
Now, in cell B6enter the following equation: Optimizing Process Manufacturing Utility costs, and other issues, are directly tied to cal poly slo thesis temperatures we use for various operations.
Perhaps, you might want to develop the habit of always making a record in the Data Recorder also part of the DataBook right before running your Case Studies. You may also want to try a two dimensional case study, Coolant Duty vs.
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.

Push Add to create a new Case Study. Perhaps, you’ve noticed our study case.
If you do not have such a file you may start from my version studdy ChemicalsEx. 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 position your cursor over the 12C3Oxide’s Molar Flow and using the secondary mouse buttondrag the number to cell B2 of the Spreadsheet.
Start by study up the file you made from the Tutorial. Therefore we must make our own Conversion calculation. 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.
