PRO/II Specifications

 PRO/II allows the use of both absolute and relative specifications in most unit operations. An absolute specification sets the parameter equal to a given value; e.g. if you wanted a flash drum overhead rate to be a set value you would use an absolute specification. The relative specification allows you to define the specification as a function of two parameters in the flowsheet. So, for example, if you wanted to set your flash overhead rate to be 80% of the feed rate you would use a relative specification, possibly something like:

Customizing PRO/II hotkeys

Many of the key PRO/II functions are accessed via the hotkeys on the toolbar. You can customize the toolbar, removing hotkeys you might not use or adding hotkeys important to yourself, by selecting the Toolbar… option from the View menu. This will open the Toolbar Customization window, allowing you to add, remove or reorder the PRO/II hotkeys.

For further details, please contact Technical Support.

Exergy Calculations

Exergy (or availability) calculations may be requested by the user by selecting the Miscellaneous Data option of the Input menu and checking the Include Exergy Analysis check box. When requested, exergy calculations are performed in the final stages of writing the PRO/II output report. As such, exergy calculations are not available during, and in no way whatsoever affect, flowsheet convergence. Exergy results appear after the Stream Summary reports in the PRO/II output report. The availability function, B, is defined as:

B = H - TS


H = enthalpy
T = temperature
S = entropy

Updating stream estimates

Updating stream estimates with solution data for streams containing pure, petro or user defined components is simple in PRO/II. After solution, select your target stream, and then select Copy from the Edit menu (or use Control-C). Next, also from the Edit menu, select the Paste Special option. In the Paste Special window that opens select the Total Stream Composition Data option and click OK. Your stream should now be updated with the solution data. Note assay generated pseudo components cannot be copied in this way. For further details, please contact Technical Support.

PRO/II Results Viewing Options

In PRO/II the default viewer for viewing results (from the spectacles hotkey or right mouse click View Results) is Notepad. You can change this to your default browser, so that results are displayed using Netscape Navigator or Internet Explorer. The viewer can be changed by selecting Viewer from the Options menu and checking the Default Browser option. Advantages of using the browser viewer include the ability to find relevant information quickly using hotlinks and drag/drop of data directly to Excel. For further details, please contact Technical Support.

From Automation World magazine newsletter: Automation Applied: Refinery Optimization

This is a short video from the Automation World magazine newsletter: "Automation Applied: Refinery Optimization".

In this short video, Abhay Sawant on North America Technical Support showcases some new features in ROMeo 6.0. This video was filmed at OpsManage in Nashville, TN.

Open different file types in PRO/II

From the File menu Open option in PRO/II you can open input (*.inp) and output (*.out) files as well as model files (*.prz or *.pr1). All you need to do is select the appropriate file type from the Files of Type combo-box in Open Simulation window. For further details, please contact Technical Support.

PIPEPHASE & Excel Based Reports

PIPEPHASE has the capability to generate Excel based reports. After the model is solved, click on the Excel button in the Run Simulation and View Results window; this will open the Excel Reports window, where you can select the report options. Once you have selected the appropriate report options, toggle on the Create Database and Create Excel Reports check boxes (these should be checked by default); then click on the Run Current Network button. An Excel report will be generated for the current model, which contains multiple worksheets and hyper-links to assist in navigation.

The Excel Reports window also allows the used to “batch” run the current model or a number of models. 

For further details, please contact Technical Support.

Pitfalls in Process Simulation - #1: Bad Data Entry

And the #1 Pitfall in Process Simulation.....BAD DATA ENTRY!

Bad data entry is the easiest mistake to make when doing process simulation.  Most often, units of measurement are the largest source of errors that occur.  For example, in the specification below, we are incorrectly dividing a mass flowrate by a molar flowrate. 

Sometimes these incorrect units of measurement are minor mistakes that play no impact on our modeling.  More often than not however, a mistake in units of measure can be a major problem.  A perfect example of this is the Mars Climate Orbiter (MCO).  Launched in 1998 by NASA to study the climate, atmosphere, and surface changes on Mars, communication with the MCO was lost after the MCO passed behind Mars, and the result was a permanent loss of communication and $328 million.  When investigated, it was found that the use of English units of measurement instead of Metric units of measurement caused the MCO to have an underestimated spacecraft trajectory. 

To ensure that errors like this do not occur, we must use many different ways to help us ensure that our data entry is correct.  As NASA’s associate administrator for space science at the time of the MCO, Edward Weiler, once put it, “People sometimes make errors.  The problem here was not the error, it was the failure of NASA’s systems engineering, and the checks and balances in our processes to detect the error.  That’s why we lost the spacecraft.” 

Here are some ways that you can help ensure proper data entry in your process simulation files –

  1. Checks and balances: Check the data that you entered after you entered it.  Make sure that it matches what you intended to enter, paying close attention to the units of measurement.
  2. Organize your work: Have all of your information ready for entry, in the units of measurement that you need for data entry.  Keep everything in an organized manner so you can go through everything easily and double check as you go. 
  3. Minimize distractions: Try not to perform tasks like data entry without staying focused.  Turn off distractions, like radios, TVs, etc.  Close out of other windows, like web browsers or another pieces of work you were working on.  Try to keep side conversations with co-workers, friends, or family to a minimum or eliminate them all together.  Anything you can do to keep focused will help.
  4. Use “alternate forms” of data input: Copy/paste information from one source to another.  Import data from a data historian.  Use data links, such as defines in Pro II, specifications, etc to ensure that the proper data is being entered into the data entry field at all times.
  5. Don’t ignore warning messages:  While most warning messages are often there just to keep you informed in case it is something that you should be worried about, others (especially error messages) often tell you of a major problem in your simulation.  Be sure to always review any messages, warnings, and/or errors the program gives you.
