Chapter 1Using PRO/IIThis chapter describes how to start and exit PRO/II. In addition, it reviews somebasic Windows features as they appear in PRO/II and briefly describes how touse them.
Before Starting PRO/II
If you have not yet installed PRO/II on your system, see the PRO/II PC/LANInstallation Guide.
If you do not see a PRO/II icon in a SIMSCI group window or in yourProgram/SIMSCI Start menu, see the troubleshooting section in the PRO/IIPC/LAN Installation Guide.
Compatibi lity with Previous Versions
This release of PRO/II can read simulation files created by previous versions ofPRO/II. When you open a simulation file created by a previous version, the file isautomatically converted to the current version, and a copy of the original file issaved under a different name. For example, if you open G3.prz that was createdby PRO/II version 6, the converted file will be saved as “G3.prz” and a copy ofthe original file will be saved as “G3_v60.prz”.
Note: Some keyword input files created manually may include features that arenot supported by the PRO/II graphical user interface. PRO/II issues awarning when this occurs. For flowsheet execution, all features will bepreserved if you choose either the Read Only or Run Batch mode.
In all cases, if you subsequently export the problem, all un -supported features will be lost. The exported file will no t includeany of the unsupported features. Later import of an exported filewill reveal that the unsupported features are missing. It is alwaysprudent to make copies of your orig inal files and to work only onthe copies of the original files.
Starting PRO/II
To start PRO/II:
Double-click the PRO/II icon, or launch from the Start menu.
The PRO/II welcome window appears. This window contains information onopening files and on the color codes used in the program.

Chapter 2Simulation BasicsIn the previous chapter, you learned some of the basic window features ofPRO/II. In this chapter, you will learn simulation basics; that is, how to set upsimulation problems, solve them, and analyze the results.
General Approach
This chapter provides a quick overview of the use of PRO/II for solvingengineering problems. A suggested basic approach is given as well as helpfulexplanations of the information flow in PRO/II. Sample data entry windows aregiven to illustrate data entry for PRO/II. Step-by-step examples are available inthe PRO/II Tutorial Guide. Online help is also available.
You have already learned that PRO/II gives you great flexibility and numerousoptions when supplying simulation data. For many items of data, default valuesare supplied. A color code informs you when data are required, supplied bydefault, out of normal ranges, or missing.
Note: You must supply data for all red-bordered fields or red-linked text(including data required) before running your simulation.
Problem data may be supplied in almost any order: PRO/II warns you whenrequired data are missing. However, it is still best to follow a logical path whensupplying simulation data. For example, some options such as streamcompositions are dependent upon the components selected. Some unitoperations, such as the flash drum, have features that are dependent on the
thermodynamic data. For some other unit operations, performance specificationsbased on the components in the system are the preferred way to define theoperation.
For these reasons, the following approach is recommended when building asimulation flowsheet.
Draw the Flowsheet
Select the unit operations needed for the flowsheet calculations and positionthem on the PRO/II PFD main window.
Connect the Unit Operations with Streams
The streams are the connectors for the process calculations, with informationpassed from one unit operation to another via the process streams.
Chapter 2 Simulation Basics 21
8/20/2019 User Guide of PRO II 9.3
34/414
Define the Components in Your System
It is best to order the components in volatility order, starting with the lightestcomponent. This makes it easy to analyze the separations which occur in unitoperations such as distillation. While not a necessity, for hydrocarbon/watersystems, defining water as the first component is also a good idea. This makes iteasy to see the break between the aqueous and non-aqueous phases. User-
defined petroleum pseudo components and/or polymer components for whichyou supply data should be entered next. Petroleum pseudo-componentsgenerated by PRO/II from petroleum stream assay data will appear last in thecomponent lists of the output reports.
Select the Thermodynamic and Transport PropertyMethods
For many problems, a system may be selected from the Most Commonly Usedthermodynamic methods. Guidelines for thermodynamic methods are provided inthe PRO/II online help, and in the PRO/II Reference Manual (both in online helpand in hardcopy forms). Further assistance is available through SIMSCI
Technical Support. Selecting a proper thermodynamic method is a criticallyimportant step in the solution of a simulation problem.
Supply Data for the Feed Streams and Recycle Streams
You must supply thermal conditions, flow rates, and compositions for all externalfeed streams to the flowsheet. It is usually desirable, although not necessary, toprovide estimated data for recycle streams to speed convergence of recyclecalculations.
Supply Operating Conditions for the Unit Operations
Double-click the icon for each unit operation to access the data entry windows.The color codes tell you what data you must supply and what data have defaultvalues. You may also use the online help to learn more about the calculationoptions, data entry items, etc., for each unit operation.
A quick review is also a good idea at this point. Do the thermodynamic methodssupport the unit operation calculations? Are transport properties required for anyof the unit operations?
Run the Process Simulation
PRO/II lets you know, by color code, when sufficient information has been
supplied to perform the calculations. When all of the borders on the toolbaricons have changed from red (indicating missing data) to green or blue, you areready to run your simulation. At this point, you may click the Run (right arrow)icon on the Run toolbar or the Run button on the Run menu to begin theflowsheet calculations.
22 PRO/II User Guide April 2014

35/414
Analyze the Simulation Results
Use the many convenient report and plotting features of PRO/II to analyze thesimulation results. At this point, your training as an engineer should take charge.Are the results reasonable? How do the results compare with the plant data?Can differences be reconciled? Are better data for the feed stocks needed? Arethe models adequate for the intended purposes?
Now that we have presented an overall plan for simulating a flowsheet, let’s lookat some of the individual steps in more detail.
Building the Flowsheet
Unit Operations
Use the floating PFD palette to begin building the flowsheet. The icons andnames for the unit operations appear as buttons on the PFD palette. To add aunit operation to the flowsheet, click the unit icon on the PFD palette and click-drop it at the desired location on the flowsheet.
StreamsClick the Streams button on the top of the floating PFD palette. The PFD is nowin stream mode and a small “S” is attached to the cursor. You will notice that allpossible exit ports for each unit operation are now marked. Required outlet portsare colored in red; green is used to mark optional ports. PRO/II adds eachstream to the flowsheet in an orthogonal manner, following a rectangular gridpattern.
As soon as a valid flowsheet has been built, i.e., all required inlet, outlet, andconnector streams have been added for all the process units, the red border
around the Streams button on the PFD palette changes to blue.Required Data
Now that the flowsheet has been built, it’s time to supply the required data for thecalculations: the components and thermodynamic methods must be defined, inletfeed streams and, optionally, recycle streams must be supplied, and theoperating conditions for the unit operations must be specified.
Components
To define the components, select Input/Component Selection from the menu baror click on the benzene ring toolbar icon to open the Component Selection mainwindow. Note that this icon has a red border, indicating that components havenot yet been defined.
Chapter 2 Simulation Basics 23
8/20/2019 User Guide of PRO II 9.3
36/414
Library components for which the library access names are known may bedirectly typed into this window, where they are transferred to the List of SelectedComponents for the problem. A convenient search procedure is also providedwhich may be used by clicking Select From Lists… Petroleum (PETRO)components are defined in the Petroleum Components window, which is reachedby clicking Petroleum…. Non-library components can be defined in the User-defined window which is reached by clicking User-defined….
Note that petroleum pseudo-components defined by PRO/II from petroleumstream assay data do not appear in the Component Selection main window.
Thermodynamic Methods
Thermodynamic methods are defined in the Thermodynamic Data main windowwhich is reached by selecting Input/Thermodynamic Data from the menu bar orby clicking on the phase diagram icon. Note that this icon is initially outlined inred, indicating that thermodynamic methods must be defined for the problem.
For most problems, a predefined set of thermodynamic methods for calculatingK-values, enthalpies, entropies, and densities may be used. PRO/II offersnumerous Categories of method sets. After a category has been selected, youmay select a method set within that category as a Defined System for theproblem and modify it by clicking Modify… to access the ThermodynamicSystem-Modification window. Note that transport property calculations are notincluded in the predefined method sets. If they are required for the problem, youmust add them to the predefined thermodynamic method set in this window.
Stream Information
The identifiers for feed streams requiring input data are marked with red bordersindicating that information is missing. Stream information is supplied in theStream Data main data entry window which is reached by double-clicking astream identifier. The predefined stream identifier may also be changed in thiswindow.
Three types of information must be supplied in this window: the thermal conditionof the stream, the flow rate for the stream, and the composition of the stream. Forpetroleum assay streams, the assay data are provided instead of the compositiondata, and PRO/II defines the stream composition for you in terms of petroleumpseudo-components.
Although optional, it is good practice to provide reasonable estimates for recycletear streams in order to accelerate convergence of problem recycle calculations.
Unit Operations
Unit operation identifiers for which data entries are needed are marked with redborders. To enter information for a unit operation, double-click its icon to retrieve
24 PRO/II User Guide April 2014
8/20/2019 User Guide of PRO II 9.3
37/414
the Unit data entry window. Various input options and numeric values aresupplied via this parent window and its child windows. Required information isalways bordered in red; data entry fields for items with supplied defaults arealways bordered in green. After supplying information in a data entry field, theborder color changes to blue. Information you have supplied which lies outsidethe normal range for the field is marked with a yellow border.
You may also change the default unit identifier in this window and furnish a
longer, more descriptive name for the unit operation. Notice that when you returnto the flowsheet, the unit identifier on the PFD has a black instead of red border,signifying that all data entry requirements are satisfied. If the border is still red,you must return to the data entry window for that unit operation and supply themissing data.
Optional Data
Miscellaneous Data
All data entries in these categories are optional because PRO/II provides default
values for all the options. In some cases, global values may be used to supplythe defaults, as explained in Chapter 4, Building a Flowsheet.
Miscellaneous data categories include problem descriptive information, thecalculation sequence, recycle convergence options, flowsheet tolerances, andthe scaling of product streams.
Problem descriptive information is optional; however, it can be beneficial todocument a simulation model for future users. This information includes a projectname, problem name, user name, date, site, and problem description. Thisinformation is supplied in the Problem Descriptive Information window, which is
accessed by clicking the toolbar icon with the printed page icon or byselecting Input/Problem Description from the menu bar.
For most problems, the calculation order determined by PRO/II is satisfactory. To
supply your own sequence, click the toolbar icon with the two connectedflowsheet blocks or select the Input/Calculation Sequence from the menu bar .
Definitions of recycle loops are automatic. To define your own loops, or to use
acceleration techniques, click the toolbar icon with the flowsheet loop icon toenter the Problem Recycle Convergence and Acceleration Options window orselect the Input/Recycle Convergence from the menu bar.
Flowsheet tolerances are used for convergence of unit operation specificationsand may be changed in the Default Unit Specification Tolerances window, whichis reached by choosing Input/Flowsheet Tolerances from the menu bar.
All flowsheet results may be scaled so that a desired flow is obtained for aproduct stream. To use the scaling feature, select the Output/Report
Chapter 2 Simulation Basics 25
8/20/2019 User Guide of PRO II 9.3
38/414
Format/Miscellaneous Data. Click Product Stream Scaling… on theMiscellaneous Report Options window to access the Scale Stream Flow ratewindow.
Miscellaneous Calculation Options
PRO/II has default settings for many global calculation settings, but in somesimulations it may be desirable to employ alternative settings. The options
described here correspond to entries in the General Data category of keywordinput. They are more fully described in Chapter 5 of the PRO/II Keyword InputManual. Note: Chapter 4 of this Guide describes additional settings availablethrough the Options menu.
To access these calculation settings in ProVision, navigate to Input/Miscellaneous Data from the menu bar. This displays the Input MiscellaneousData dialogue:
Figure 2-1: Miscellaneous Calculations Options Include Exergy Analysis: Placing a check mark in this checkbox requests
exergy calculations after the flowsheet has solved. These calculations donot affect flowsheet convergence. This corresponds to the EXERGYstatement of General Data keyword input.

Component Data: Controls the component slates used in eachthermodynamic METHOD set. The default Fixed option forces allthermodynamic sets to use the same component properties uniformly.The Variable option allows each METHOD set to use different propertiesfor the components. This is equivalent to the CDATA option on theCALCULATION statement of General Data keyword input.
Polymer Mode Consistency Check: Set Yes by default, this generates a
report of how the phases available for polymer components agree withthe phases available in the thermodynamic methods. This option takesvery little time, and there is no substantial advantage for using the No option. This is equivalent to the PCONVERSION option on the PRINTstatement of General Data keyword input. (It is used so rarely it nolonger is documented in the Keyword Manual.)
Thermo/Phase Designation Consistency Check: This checks that thephases declared in the thermodynamic METHOD sets are compatiblewith the phase designations of non-polymer components. The defaultCalculation Time setting performs the checks each time thermodynamic
calculations are initiated. The Input Time option performs the checksonly once, before flowsheet calculations begin. Performing the checksduring calculations has very little impact on the elapsed solution time.This is the same as the COMPCHECK option on the CALCULATIONstatement of General Data keyword input.
Independent Variable Check: In equilibrium calculations where thedependent variable (y) is relatively insensitive to the independentvariable (X), the default ON setting forces relatively large changes in theindependent variable. This helps ensure the solution is near the localoptimum. The OFF option accepts any valid solution that is merely“within tolerance”, but may be desirable in rare situations. This isequivalent to the DVARIABLE option on the CALCULATION statementof General Data keyword input.
Flash Algor ithm: PRO/II incorporates several strategies for solving flashcalculations. Each strategy has unique strengths and weaknesses. TheDefault setting is robust, and is appropriate for most simulations. Thebefore Version 5.5 setting closely replicates the flash results obtained inolder versions of PRO/II. The Alternate setting is recommended whenthe Default method fails, especially when two liquid phases areexpected. For more description, refer to the FLASH option on theCALCULATION statement of General Data keyword input.
Maximum Node Calculations: This entry sets the maximum number of unitoperations and branching decisions allowed during flowsheet solution.The default number is adequate for virtually all simulations. See theMAXOPS entry on the CALCULATION statement of General Datakeyword input.

Default Data
To simplify data input, PRO/II supplies default options and values whereverpractical. Default values supplied by PRO/II are printed in black in a data entryfield with a green border, or in the case of linked text, in green. For example, thedefault number of iterations for a column unit operation using the IO method is
supplied as 15. Entries which you must always supply are indicated with a colorred because they have no default values.
While it is not necessary to replace a default entry to satisfy PRO/II inputrequirements, default data should be inspected carefully to ascertain that theymeet your requirements. After replacing a default value, the border color for thedata entry field changes to blue, indicating that you have supplied this value. Forlinked-text strings, the color of the linked text is also changed to blue, indicatingthat you have replaced the default value.
Other Optional Data
Optional data, which are displayed in black, are data or options not specificallynecessary for the unit operations to proceed. For example, the Description entryis optional for all unit operations. A reboiler is optional for the Column unitoperation, since the calculation requirements may also be satisfied by a vaporfeed to the bottom tray of the column.
Data options which do not apply to a particular combination of input data appearin the color gray, and are not available for data entry. For example, when thekettle reboiler option is selected for a column reboiler, the data entry fields for athermosiphon reboiler are colored gray.

Keyword Features without PRO/II GUI support
The RESTART feature is not supported by the graphical user interface in thisversion of PRO/II. You will not be allowed to import keyword files that contain thisfeature.
If a RESTART keyword is detected upon import, you will be reminded that onlythe “Run Batch” feature of PRO/II may be used with these keyword input files.
See Chapter 10, Running and Viewing a Flowsheet, for information on runningkeyword files in “Batch” mode.
Keyword Features Imported in “ Run-Only” Mode
Certain keyword features are not fully supported by the graphical user interfaceof PRO/II. However, if one of these unsupported features is detected, you will beallowed to import the keyword file, however the GUI interface will operate in the“Run-Only” mode. Such unsupported keywords include:
BVLE Data
Hydrate Unit Operation
HEXTRAN Property Data Generator.
If you attempt to import a keyword input file that contains PRO/II programfeatures not supported by the graphical user interface, the unsupported featureswill be automatically listed in a status window. You have the option to save ordelete the unsupported features. If you choose to save the unsupported features,PRO/II will run the file in Run-Only Mode.
In “ Run-Only” mode, you can:
• Review and modify the PFD graphic image. You may move unit
operation icons and streams around to improve the appearance of yourPFD.
• Add drawing elements to the PFD.
• Add stream property tables to the PFD.
• Have access to all the capabilities on the Run toolbar (perform allinteractive execution functions available on the Run toolbar for bothsupported/unsupported units, review the calculated results on the PFDfor all streams and supported/unsupported units, generate output reportsfor all features, generate plots for supported features only).
• Export the flowsheet and stream property table information to otherWindows applications.
• Edit the keyword file, re-import, and rerun (without leaving PRO/II).

Removing all unsupported features in the dialog boxes allows PRO/II to startnormally. However, leaving even one unsupported feature present results inPRO/II operating in “Run-Only” mode. The Title bar of the main PFD windowreveals this condition, as illustrated in Figure 3-9.

Exporting Simulation Data to a File
PRO/II allows exporting the current simulation flowsheet in a variety of differentformats for use in various applications. To begin the export process:
Choose File/Export… from the menu bar. PRO/II displays the Export window which lists the data export options. Refer to Figure 3-10.
Figure 3-9: Available Data Export Options
Note: In the current version, a *.sfd file is generated when the simulation(PFD) is saved and exported. After generation of the *.sfd file, users canrestore the PFD layout using the (exported) *.inp file.

Choose the Simulation Data to Keyword File option.
Click OK.
PRO/II converts the current simulation flowsheet data into a PRO/II keywordinput file in ASCII format. The name of the keyword file will be YYY.INP, whereYYY.PR1 is the name of the simulation flowsheet PRO/II database file.
Export Simulation Data to a Keyword FileThis selection opens a special Save As… dialog window that allows exporting theinput data of the simulation to an ".inp" keyword input file.
Navigate to the destination drive and directory of choice using the SaveIn: field.
Enter the name of the output file in the File Name: field.
Press the Save button to complete the operation.
The exported keyword file then may be imported into any compatible version ofthe PRO/II program to rerun the simulation, even on another computer. Keywordfiles also are a very compact way to archive the data. Note that the keyword filecontains all the appropriate data sections (General, Thermodynamics, etc.).
In v6.0 and later, the "Simulation Data to Keyword File" option is expanded toinclude check boxes to control exporting stream and column solution data to thekeyword file.
If output data exists, even if the solution is unconverged, the two "Include" checkboxes are enabled (See figure 3-10). If the Run command was never executed,or not executed since the last time "Restore Input Data" was performed, thesecheckboxes are disabled.Test for Convergence
When the user selects either or both of the "Include" check boxes (Figure 3-10),upon OK, the first thing PRO/II does is test for convergence. If the solution is inan unconverged state, PRO/II displays a message box to warn the user that thedata being written to the keyword file is unconverged.
Clicking "Yes" continues to the file name selection common dialog. "No" returnsthe user to the Export window.
Note: Beginning with PRO/II version 5.5, exported flowsheets write all unitoperations in the flowsheet to the keyword file. Previously, for keyword input filesthat include a User-Defined Sequence List, only unit operations listed in the
Sequence List were exported.
This change was necessary to support the new Included/ Excluded functionality.PRO/II now generates a SEQUENCE statement with a list of Available UnitOperations that excludes unit operations marked Excluded at the time of export.Additionally in these instances, PRO/II writes a warning into the keyword fileadvising that the list of unit operations and the SEQUENCE statement do not

match. These files may cause input processing problems if read into earlierversions of PRO/II (i.e., versions prior to 5.5).
Exporting the Flowsheet Drawing to the Clipboard
You can export part or all of the flowsheet drawing to the Clipboard. You canthen paste this drawing into other Windows applications.
To export the entire flowsheet drawing to the Clipboard: Choose File/Export from the menu bar. PRO/II displays the Export
window (Figure 3-10).
Choose the Flowsheet Drawing option.
Click OK.
To export one page of the flowsheet to the Clipboard:
Select the page to export by clicking on its edge on the PFD.
Choose File/Export from the menu bar. PRO/II displays the Expor twindow (Figure 3-10).
Choose the Selected Page of Flowsheet Drawing option.
Click OK.
Exporting Stream or Unit Property Table Data
You can export the information in a stream property table or a unit operationproperty table to an ASCII file. The file subsequently may be imported intospreadsheet and word processing applications.
To export data from a stream or unit operation propertytable:
Select the property table to export (select it on the PFD).
Choose File/Export from the menu bar. PRO/II displays the Exportwindow (Figure 3-10).
Choose the Stream / Unit Op Property Table option.
Click OK. The Export File Filter window will appear (see Figure 3-11).
Enter a name for the Output File.
Select the desired file format (tab-delimited or comma-delimited) from theSave File as Type drop-down list box.
Click OK.

Exporting Stream Property Table Data to StreamReport Writer
You can export the information in a Stream Property Table to a keyword filewhere it will persist as a Stream Report Writer by using the “Exporting SimulationData to Keyword File” option. The Property Table name and the specifiedstreams for each table are exported onto an OUTPUT statement and the
Property List definition is exported onto a FORMAT statement.
Exporting the PFD to an AutoCAD
You can export your flowsheet drawing as an AutoCAD .DXF file:
Choose File/Export from the menu bar. PRO/II displays the Exportwindow (Figure 3-10).
