CASE STUDY is easier to learn how to use PROVISION by doing a simple case study. Let s start bylooking at a simple compression system.

1000 lb. moles per hour gas mixture containing 5 methane, 20 ethane,25 propane, 30 n-butane, and 20 n-pentane at 14.7 PSIA and 90F is to becompressed first to 50 PSIA, then to 200 PSIA using a two-stage compressorsystem. An inter-stage cooler is used to cool the compressed gas from eachstage to its original temperature. A knockout drum is installed after the firstcooler to remove any liquid present in the compressed gas before feeding it to thesecond compressor.

Let s solve this case step by step using PROVISION.

STEP 1: Identifying the CaseBefore starting PROVISIo N,. it would be a good idea to draw a process flow diagram(PFD) on a piecq paper. When drawing a PFD, try to label each unit and streamsystematically, so you can easily identifY them. The purpose a PFD is to visualize theprocess and to roughly understand the case. A rough sample PFD should look like this:

GiL> It would be a good idea to write down all the known data for Don t tryto do any calculations by yourself, because PROVISION does That s theofo ,g , p,oo,,, , moW pw _

STEP 2 Starting PROVISIONOnce the basic PFD is drawn and the problem has been identified, you are ready to startPROVISION. To start PROVISION double click on the PrOlision 1 2 icon in im igroup. You will be greeted with a welcome menu. Read the menu. It tells you somebasic things you need to know when using PROVISION.

STEP 3: Drawing PFD Using PROVISION

The first step for approaching a case is to draw a complete process flow diagram. Todraw a PFD, follow these steps.1 Click on New on File menu to start a new case.2 Move the mouse to the palette showing units. For list of units available in PROVISION,refer to

Appendix B

3 Using the figure drawn as a guide, select needed units and place them on the PFD oneby one. Click on the Compr essor button and then click on the space in the PFDwhere you wish to place the compressor. Follow the same steps for Simple HX 1),Flash ompressor 2), and Simple 2). You will notice that each unit is namedby PROVISION, automatfcally. You will also notice that each name has a red bordermeaning that the condi/ions have to be supplied.

Click on the stream button on the build palette to draw the stream lines. All thepossible E XI T ports appear on each unit as soon as the stream button is selected.The required outlet ports are colored red, while the optional exits are given in green.

Add streams by clicking on the origin of the stream either a unit exit por t or anex :ernal feed stream, on a unoccupied part of the PFD), then click again at thedestination of the stream. Continue until all streams have been added to the PFD.

xample To apply a feed stream to l click on PFD that s not occupied by any unit,then click again at compressor. Notice the name is give as S

5 Connect all the streams in order shown in Figure I. Pay special attention to thenumber of streams. Each stream is numbered in the order they are created.

STEP 4: Defining the Component ListNow that the process flow diagram is drawn, you need to specifY the components that areused in the case. To enter the components, follow these steps.j Click on the l icon on the menu bar to specifY components.2 Enter the names of the components in the Component: window. Click on the I Add,

button to add each component. Type in Methane in the Component: window. Clickon the I ADd. button. Notice the box has a blue border as soon as you click on theI ADd I button, meaning that you have supplied the information. Add. the remainingcomponents Ethane Propane N butane Pentane and ater andclicking onfhe button after each component. You can also choose componentsfrom a list. To choose from a list, click on the I s h e LAt.... I button.

Cit> If you accidentally added an incorrect component to the list, you can remove thecomponent by clicking on the component and clicking on I I button.

STEP 5: Choosing a Thermodynamic SystemIn order for PROVISION to perform any kind of calculation a thermodynamic system mustbe supplied. The thermodynamic system lets the program know which calculation methodto use. Since Peng-Robinson is most commonly used lets choose Peng-Robinson byfollowing these steps. It s always safe to save frequently. To save click on File on the menu b ar and click

on Srwe on the File menu. Type in the file name ase 1 and click on the I 0< Ibu tt on to go back t o PFD.

@) Click on 1 _1 once again to return to normal PFD.When the calculation is finished, all the unit operations should be blue, indicating that allthe calculations are finished for the entire case. Once the calculations are performed, youdo not need to run the calculations again as long as you do not change anything.

Step 7: Reviewing and Printing the ResultsOnce the calculations are performed, you are ready to check the results by generating areport. To generate a report, follow these steps: D Click on Output on the menu bar in main PFD.2) Click on Generate Report on the Output menu to bring up Programmer s File ditorwindow. You can scroll up and down the report by using the scroll bars. The reportlists various information like PROm keyword input commands, component properties,unit operation results and stream results. You can also edit the report by using the ditmenu.

Printing Material and Energy Balance on PFDIn order to include material and energy balances on your PFD, you must define a propertylist first The property list tells PROVISION what to include in the material and energybalance table. Let 's define a property list that includes Stream Name, Phase, TotalMolar Rate, Temperature, Pressure, Enthalpy, and Molar Compo Fractions.CD Click on Options on the menu bar in main PFD window.(2) Click on Stream Property Lists on the Options menu.GJ Click on New List button in Deline Property List window to name the new list
