B07, SBN 2000, Release Date (12/08/2018)

 

  1. B07, SBN 2000:  New Example Added to the Food Processing Group: Cocoa Processing (Improvement)
    A new modeling example has been added to the Food Processing set of examples. It captures the operations in a cocoa processing plant that produces several grades of chocolate and cocoa powders. Chocolate is one of the most popular confectionery products in the western world, and its production is continuously increasing every year. The increasing demand, frequently leads to fluctuations of the chocolate price (as a commodity). The process presented here is based on fermented and dried cocoa beans used as raw material. Full documentation and the actual SuperPro model file can be found under the "Cocoa" subfolder in the "Food Processing" folder of all "Examples". If you don't know how to locate your "Examples" folder in your installation, please consult the relevant topic in the online help (Auxiliary Folder).

  2. B07, SBN 2000:  New Example Added to the Food Processing Group: Pectin Production (Improvement)
    Another modeling example has been added to the Food Processing set of examples. It simulates the production of pectin from citrus peels. Pectin substances are complex mixtures of polysaccharide polymers found in most plants; their concentration varies depending on the type of plant and the specific part of the plant where they are located. Pectins behave like a stabilizing gel and contribute to both the adhesion between the cells and to the mechanical strength of the cell wall. Commercial pectin is typically extracted either from citrus fruit peels or from apple pomace. Full documentation and the actual SuperPro model file can be found under the "Pectin" subfolder in the "Food Processing" folder of all "Examples". If you don't know how to locate your "Examples" folder in your installation, please consult the relevant topic in the online help (Auxiliary Folder).

  3. B07, SBN 2000:  Input Data Report Occasionally Crashed Upon Creating (any format) (Bug Fix)
    When requesting the generation of the Input Data Report (IDR) for a process model, the application may crash. This would happen regardless of the choice of output format (PDF, RTF, HTML, etc.). This has now been fixed.

  4. B07, SBN 2000:  Rigorous Distillation Model's Heating & Cooling Loads Were Sometimes Incorrectly Reported (Bug Fix)
    When running a (continuous) rigorous distillation model, the simulation engine would calculate heating load of the reboiler and the cooling load of the condenser correctly if the unit procedure was set to operate continuously (by far, the most common case). However, if the unit procedure was set to function in a semi-continuous (stop-and-go) mode, the loads were off. This has now been fixed.

  5. B07, SBN 2000:  Custom Mixing Behaved Erratically (Bug Fix)
    When using a custom mixing step, if the simulation failed to satisfy the set requirement (e.g. if the mixer was set to achieve a set amount, but the feed exceeded that value), the engine would report the error, would not adjust the input stream and simply add whatever value of flow was found there (from the previous run, or previous iteration in loop iterative calculations). This was not correct as it could lead to undesirable convergence levels or even lead to non-convergence. This has now been fixed and when the requirements can't be met, the adjustable input stream is set to 0.0 (if it's a direct input) or left unadjusted (if it required further back-propagation) but the output stream is always set to the input stream.

  6. B07, SBN 2000:  When Heavy Key in a Shortcut Distillation Was Missing its Antoine Coefficients, Application would Crash (Bug Fix)
    This has now been fixed and an error is produced instead.

  7. B07, SBN 2000:  Missing V/L Correlation Coefficients for non-SuperPro Components Were Incorrectly Reported as "Missing Antoine Coefficients" (Bug Fix)
    SuperPro Designer allows users to register component from either DIPPR or PPDS as alternative sources to its own System DB (or the User's DB that keeps components in the same data format as the System DB). Whereas SuperPro's DB keeps V/L data in Antoine format, other DBs (such as DIPPR) does not. Occasionally, a component registered from the DIPPR database may be missing its V/L coefficients. Up till now, SuperPro would incorrectly complain about that component missing its Antoine coefficients, when a more appropriate response would be, its missing a valid correlation for Saturated Vapor estimation at different temperatures. This has now been fixed.

  8. B07, SBN 2000:  When Exporting the Flowsheet Drawing to a DXF File Multi-Line Text didn't Export Properly (Bug Fix)
    When exporting the flowsheet drawing into a DXF file, any multiline text item would only export its first line. This has now been fixed.

  9. B07, SBN 2000:  When Exporting the Flowsheet Drawing to a DXF File Some Visual Objects Wouldn't Export (Bug Fix)
    When exporting the flowsheet drawing into a DXF file, any visual objects (like straight lines, polylines, circles, rectangles, etc.) wouldn't export. This has now been fixed.

  10. B07, SBN 2000:  Non-Zero Intracellular Fractions Appeared without the Presence of Primary Biomass Component (Bug Fix)
    Due to a glitch in much older versions of the software, it was possible to have intermediate streams (or equipment contents) have their composition calculated by the simulation engine and produce component flows with non-zero intracellular fractions when the primary biomass component either was no longer defined in the model, or was defined but was not present in the stream (or process state). Starting with this release we've added code that 'cleans up' any such past saved states or streams to avoid further propagation of such errors.

  11. B07, SBN 2000:  When the Major Units Were Chosen as "Months" the First Number Shown was "0". (Bug Fix)
    Due to a glitch when the major units on a time axis was chosen to be "Months", the first number shown was "0" instead of "1". This has now been fixed.

  12. B07, SBN 2000:  When Displaying Day-Month Dates, the Local Preferences Were not Respected Leading to Confusing Time Axis. (Bug Fix)
    Typically in the US, the day-month of the year in numerical form, would "mo-day", whereas in other parts of the world, it would be "day-mo". Starting with this release, the locale choices for how to display dates will be consulted before such presentations are made in order to be consistent with user's expectations.

  13. B07, SBN 2000:  When Opening Files Created prior to v10.03 the Crystallization Operation Would Fail to Read Some of Data Correctly. (Bug Fix)
    The designation as to which component is crystallizable, would fail to be read appropriate for older files (prior to v10 Build 03). This has been fixed.

  14. B07, SBN 2000:  When Renaming A Pure Component Participating in a Chemical Reaction the Name Change Didn't Propagate Properly. (Bug Fix)
    This has been fixed.

  15. B07, SBN 2000:  When Setting the Capacity-per-Volume for an MA-Loading Operation (or PBA Column Loading Operation) with a COM Engine Call, Results Was Unsuccessful. (Bug Fix)
    This has been fixed.

  16. B07, SBN 2000:  When Renaming A Pure Component Participating in a Chemical Reaction the Name Change Didn't Propagate Properly. (Improvement)
    Batch concentration operations would require that you chose at least one component with non-zero RC value. Staring with this release, we accept settings where no component is set to be retained (all component have zero RC values).
