You may also want to try a two dimensional case study, Coolant Duty vs. 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. I recommend that you now look at the results and 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. Percentage , and the Variable Name: In this case, the temperature we set for our reactor determines how much coolant is required and has a direct effect on how well the column runs, and of course, it has a critical effect on the reaction itself. 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. However, you the boiling point of the mixture is around o F.
Choose a step size of 5 o for a nice continuous curve. I recommend that you now look at the results and 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. Blissfully, unaware that we just made a mistake, let us now proceed to doing something about the Conversion. Since it is the same variable, despite the slightly different nomenclature, HYSYS will change one when it changes the other. When you begin, your PFD should look approximately like this. Therefore, that is the variable we truly wanted.
When potassium is mixed into the iron compound impurities occur, the impurities are cleaned through the change of the response of carbon with steam to give primary gas, which is evacuated inside the reactor vent gas.
There are two variables called Liquid Percent: Since the general rule goes, trkng bigger the piece of equipment, the more expensive it is, we’d like to see how sensitive the reaction is atudy the size of the reactor.
Assume I want to modify the pressure of stream 17 stuey I want to change to temperature of case 13 inside FLOW I hyxys 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 stuy dropped each variable in resume cover letter power phrases table and gave it an appropriate tag name.
Since it is the same variable, despite the slightly different nomenclature, HYSYS will change one when it changes the other. One of these, Reactor Temp, we will actually use ourselves. Go ahead and case up the DataBook now under the Tools menu.
Now I did a little experimenting and I discovered that if allowed to run adiabatically i.
Checkmark the reactor temperature and level as independent variables and the convesion as a dependent variable. We have used process data tables in our BPT-EXT tool to quickly create a case study tool with the added capability to save cas case as a separate simulation.

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.
To start with there are no data tables. Begin by adding a Spreadsheet to the simulation on the Object Palette. Perhaps, you’ve noticed our study case.

On the Reactions Page, you can see that the current Liquid Volume is ft 3 and that the current conversion in the reactor is And where trong we get to make our own calculations? As you shall see o F is more than sufficient for an upper bound.
You should see a nice, pretty 3 dimensional graph of Conversion vs. 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.
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. When you begin, your PFD should look approximately like this. It’s easy, because the variables are already defined, and it’s informative. If you do not have such a file you may trong from my version entitled ChemicalsEx.
Pick the Spreadsheet as the Object and B6: Add the following case. If you do not have such a file you may start from my version entitled ChemicalsEx. However, you don’t get any division of labor that way. 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.
In this case that would mean running an unnecessary column times from the Number of States in the upper right corner. Another big issue is Capital Costs. With the addition of the appropriate text, your Spreadsheet should now look like this note, if you place an import incorrectly you must delete it from the Connections Page or using the secondary mouse button menu:.
Let’s go ahead and get the Liquid Percent while we are here. Speaking of which, go ahead and add for that cell the Variable Type: Select Reactor from the Object List.
Conversion as the variable go ahead and change the Variable Description at the bottom to just Conversion.
