Model Development

Using  A Previously Developed HYSYS file

1. Complete the Enthalpy Tutorial.
2. Save a copy of the HYSYS file as EOS.

Changing the Fluid Package

1. Press the Enter Basis Environment icon which is located on the menu bar.

2. This should take you to the Fluid Package window. Click on the Prop Pkg tab.
3. Select the EOS's filter radio button.
4. In the list in the left of the window, scroll and select Peng- Robinson.

3. Type a P. Notice that the box above that was gray is now white. In the box, one can edit the input similar to editing and excel cell.
4. Finish typing Part c. (The results of this stream will be for part c of the problem because they were the last conditions entered in the Enthalpy tutorial.)

Copying Stream Conditions

1. Install another material stream on the PFD.
2. Open the new stream window and rename this stream as Part a.
3. In the stream window, press the Define from Other Stream button. (This is located  near the base of the Part a. window.)
4. In the window that opens, select the stream Part c. from the the available stream list.
5. For the stream conditions to copy, select  only the Composition and Flow.

3. Click on Properties.
4. In the list of properties, look for Mass Enthalpy.
5. When you have located mass enthalpy, click on the cell to the right.
6. Hold the cursor over the the selected cells. Note the numbers and units that appears in the flag.
