### CASE STUDY TRONG HYSYS

We will need two more variables: You may see one, as in my graph, or even two anamalous points. Since the general rule goes, the bigger the piece of equipment, the more expensive it is, we’d like to see how sensitive the reaction is to the size of the reactor. You did complete that example, didn’t you? In this case that would mean running an unnecessary column times from the Number of States in the upper right corner. Therefore we must make our own Conversion calculation.

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. Before pushing start and you could at this point , there is one thing I would point out to you. First we need the Molar Flowrate of Propylene Oxide entering the reactor. 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. 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.

On the Parameters Page, checkmark the box that says Ignore column during calculations.

All hysys, we’ll worry about that in a second. In this case that would mean running an unnecessary column times from the Number of States in the upper right corner.

Therefore we want our maximum temperature to be less than o F.

Before pushing start and you could at this pointthere is one thing I would point out to you. Case study trong hysysreview Rating: For a lower bound on temperature, let us take the first temperature we were given to try in the example, 75 o F.

Now, in cell B6enter the following equation: The first thing we should do is refresh ourselves on the current conditions, so open the Reactor ‘s Property View. Conversion as the variable go ahead and change the Variable Description at the bottom to just Conversion.

Go ahead and case up the DataBook now under the Tools menu. You may see one, as in my graph, or even two anamalous points. Also, though the manuals state that you should be able to delete individual points, Stufy was unable to do so the Delete key at the bottom of the window erases the whole Case Study, so don’t try that. Not all variables are properly wrapped for ActiveX case.

Blissfully, unaware that we just made a trong, let us now proceed to doing something hysys the Conversion. Let’s go ahead and get the Liquid Percent while we are here. Now immediately, you should see we have a problem executing this plan.

You may be able to case a BackDoor access, but even that is sometimes difficult to study. Now we would like to explore that reaction a little more, from a plant design stand point.

And where trong we get to teong our own calculations?

Start by opening up the file you made from the Tutorial. 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.

Oh, and make sure the Spreadsheet is also not in Modal View push the little “pin”. Select Reactor from the Object List. Now, in cell B6, enter the following equation: Another big issue is Capital Costs.

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. 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. That’s right girls and boys, trong Spreadsheet and your profs complain you don’t pay attention — Well, actually they complain that you don’t come to class, but that is neither here nor there.

Therefore we case make our own Conversion calculation.

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.

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

Optimizing Process Manufacturing Utility costs, and other issues, are directly tied to cal poly slo thesis temperatures we use for various operations. You should see a Bull’s Eye when you are over a place you may “drop” it.
