Miscellaneous Report Options
This window is used to specify the report dimensions and to select options for printing input data, mass balance, etc. Additionally, you can change the flowrate of a product stream to a desired value and PRO/II scales all streams and most of the units in the flowsheet corresponding to this rate.
Usage
From the "Report Format" command in the Output menu, select the "Miscellaneous Data" item to display this window.
Dimensions of Report
Select the appropriate values for the following options to control the appearance of the report:
Report Width
Controls the width of the page used for output report. The widths available are 80, 120, or 132 columns. The default page width is 80 columns. If the physical page cannot accommodate the selected width, the printing wraps around to the next line. Typically, the first column (column 1) is a non-printing column used for printer carriage control. Also, the last column (column 80, 120, or 132, depending upon the selected page width) is left blank. This allows the cursor on a video terminal to occupy the last column without causing the display to wrap the line. This also means the number of actual printed columns always is two less than the declared nominal width.
Report Length Per Page
Controls the maximum number of lines printed on a page. Any number of lines greater than zero may be specified. By default, 60 lines are printed per page. Note that this does not define the physical length of the page.
Input Data Summary
You may request a summary of some of the primary data that was used for the simulation. The information that can be printed are:
Component Data Input Parameters
The property values for all the pure components in the simulation. It includes properties like molecular weight, density, normal boiling point, critical properties, heat of formation etc.
Thermodynamic Data Input Parameters
The thermodynamic property values (interaction parameters, etc.) for all the components in the simulation according to the thermodynamic method selected.
Calculation Sequence and Recycle Loops
This option prints the unit operation calculation sequence that was followed to solve the simulation. The tear streams and starting and ending units of each recycle loop are included in the report.
Refinery Inspection and User-defined Special Properties
You can request output of the Refinery Inspection and User-defined Special Property data. The options are:
Include Input Data: Show the user-supplied data.
Include Program Data: Show the data calculated by PRO/II.
Use these options to extract a variety of results data from the simulation database and export them to plain-text files. The data include computed values as well as input data, but it is exported in a form suitable for inclusion directly in a keyword input file, or into another program. Most data is exported to a single file. On a PC computer, the file name typically includes the suffix ".P2I". The only option that is different is "Generate ASC Files" , which writes a file with the suffix ".ASC".
|
Generate All Database Statements |
Checking this item selects all options except Generate ASC Files. It also disables all the options indented below, since essentially they all have been selected. This function and all of its subordinate options write data to the ".P2I" file. |
|
Generate a SEQUENCE Statement |
Exports the calculation sequence used in the simulation. The form is a keyword SEQUENCE statement. |
|
Generate Pseudo Component Property Statements |
Generates PETRO, NBP, SPGR, MW, PC, TC, and ACENTRIC keyword input statements for all pseudo components in the simulation. |
|
Generate Property Statements for all Streams |
Writes a complete PROP statement for every stream in the simulation, including temperature, pressure, and component-by-component composition. |
|
Generate Column Profiles |
Creates keyword input statements that define the temperature, pressure, vapor, and liquid profiles for every distillation column in the simulation. |
|
Generate Intergraph PDS Stream Files |
Produces a stream data file in "Load File" format (a proprietary format). THe data written by this option is in a form suitable for importation by the Intergraph Process Design System. |
|
Generate ASC Files |
Creates a ".ASC" file and writes a complete set of results data to that file. This is an "all or none" function; there are no options to control what data is written to the ".ASC" file. |
Overall Flowsheet Mass Balance
This option prints the overall mass balance for the entire flowsheet in both molar and weight basis. The details regarding the feed and product compositions, and any amount lost or formed due to reaction(s) are printed. The deviation value, which shows the amount of unaccounted material after the total material entering and leaving the system is balanced after any reactions, is also printed. This value reflects the precision of the simulation calculations, and indicates if the specifications supplied for the simulation are realistic. By default, it is included in the standard output report. From the Output menu, navigate to Report Format, then Miscellaneous Data. To skip the mass balance, simply uncheck the box next to the item labeled Include Overall Flowsheet Mass Balance.
Additional Unit Operation Results on Weight Basis
This option causes each unit operation to print additional results on a weight basis, as if solids were present, even when no solids appear in the flowsheet.
Suppress All Warning Messages in the Output
If this option is selected, no warning messages will appear in the output report.
Suppress Output for Components with Zero Flow rates
When this option is selected, components having flows below a minimum trace threshold will be omitted from stream reports and other selected sections of the output report. For example, many electrolyte models include a number of ionic species that may not be of interest in a specific simulation. Although the electrolyte model being used forces these species to exist in the flowsheet, they may not be involved in the simulation. In such a case, they are of no interest, and have flow rates that are essentially zero. Invoking this option eliminates such unwanted components from most sections of the output report. Conversely, if a user is interested in the behavior of trace components, this option probably should not be activated.
Print Calculation Sequence Map in the Output
Having a map that lists the order in which a flowsheet is solved often is useful. Now that PRO/II provides users the ability to activate or inactivate individual unit operations, it is more useful than ever. Previously, a sequence map could be generated only by using key word input data. Now, the sequence map is available through the Graphical User Interface. By default, it is included in the standard output report. From the Output menu, navigate to Report Format, then Miscellaneous Data. To skip the map, simply uncheck the box next to the item labeled Print calculation sequence map in the Output.
Electrolyte Specific Output
You may select additional output for electrolyte calculations. Partial adds pH and ionic strengths to output tables and adds tables of ionic species. Complete adds the Electrolyte Thermo Summary table to the output.
Product Stream Scaling button
Push this button to display the "Scale Stream Flowrate" window, where you can scale the flowrate of a selected stream in the flowsheet to generate results according to the scaled flowrate. Note that you cannot scale the flowsheet when certain units are present and this button will not be available in these cases. See Scale Stream Flowrate for more details.
