• Equilibrium constants (Keq) values in the reports were reporting the exponent of the value (-14 instead of 1.0E-14). This has been corrected to display the true equilibrium constant
• Databases brought upto ESP 8.0.58
• Solvers brought up to ESP 8.0.58

General Release

All Products

• The report writer did not properly calculate the total number of moles per phase in the summary section. It was correct in the speciation section. This has been corrected

Steam Analyzer

• Yield diagrams could fail to display properly in some rare cases. This was linked to two different types of variables being passed between the FORTRAN solver and the C++ User interface. This has been corrected.

All Products

• The database importer was updated to handel old format databases.

All Products

• The security dialog was updated such that all security options are access from a single dialog.

All Products

• A general enhancement to improve the speed of calculations was made. Some large cases may see a 4x improvement in speed
• The Survey input grid mini-tab report was modified to shorten the name. Instead of seeing point 4 of 200 you will now see 4 of 200

All Products

• The database importer utility under Chemistry > Model Options failed to import old ESP format databases. This was updated. A patch for version 2.0.52 is available by clicking here: Patch
• MSE: Vapor Viscosity has been added.
• MSE: Vapor Viscosity grid has been added. The relative viscosity between vapor species will be displayed as a grid. This will be available for single point calculations only and only available in the report. The default is not to calculate or display these results
• Pass-trough DBS files are now re-enabled. You can now use a model created in ESP or with the chemistry wizard in the Analyzers.
• You can now sort your stream by name and the listing will be saved. Previously your stream were sorted in the order they were created.
• The mixed stream grid has been updated such that it does not expand to an unreadable size when using long stream names.
• MSE The species NaOH(aq) was removed from the MSEPUB database. The species table for existing models could become corrupted if NAOHAQ was present. The code was modified to trap-out the species NAOHAQ and force a model regeneration.

Security

• Network
  • An option was added for checking licenses out from a network installation. Commonly referred to as a commuter option.
• Downloads
  • New versions of the software that can be downloaded can be locked to a specific build number. This is so users of perpetual licenses can get replacement copies of the software

All Products

• The security provider was updated to test for a likely condition where a plug-in was enabled (usually during a trial) that is no longer licensed. A frequent example is using the Corrosion Analyzer as a plug-in during an OLI course (trial copy) and then licensing the software without the Corrosion Analyzer. Just updating the serial numbers will result in the infamous error message "Security provider failed to login in product". The program will now display this message but it continue to load

Chemistry Wizard

• The generator was updated to allow for equilibrium equation lengths to exceed 60 characters

All Products

• When saving a file and a background calculation is in progress, the object is displayed for informational purposes. It is rare that a user will encounter a situation where this is useful

All Products

• Off line files (used for files on shared network drives which are synched) causes file save issues. This is a problem in all OLI windows products prior to February 26, 2007. A change in the Microsoft Foundation Class libraries fixes this. The Analyzers have been patched to work-around the off-line file issue.

Corrosion Analyzer

• A FORTRAN compiler option was not properly set for the Analyzer solvers which caused the Corrosion Analyzer to report different corrosion rates for sulfur containing systems than did the CSP program.

All Products

• An error with large surveys could cause garbage data to be saved with the file. This creates large file sizes and frequently resulted in crash on open errors. A clean-up routine has been added to clean up the file when saving. A pre-processing routine has been added to attempt to open previously saved files with the garbage data.
• Composition surveys in concentration units (such as molarity) may experience convergence problems. Users should avoid this unit for solving and convert back to molarity after the calculation has completed

SECURITY

• HARDLOCK:
  • 64-bit drivers for Microsoft Windows Vista are now included in the install set
  • Hardlock Installation Failure: When a failure occurs, the Hardlock Reset button now becomes the Hardlock Repair button and launches the batch files to update the hardlock drivers. This frequently occurs when upgrading from a Timelocked version.
• NETWORK:
  • Vista does not permit the broadcast of server names. Users will have to specify the server name or IP address in the client security settings.

Internal version numbers were out of synch with the version numbers of main-line programs. The version numbers were updated.

Lab Analysis

• When converting from an ionic view to molecular view (or clicking the 'Add as Stream' button), the resulting total mass could be in error. The molecular weight for each species was cached to speed up the process. The cached values were not updated properly and could results in an internal divide by zero or a divide by a wrong weight. This has been corrected.

MSE

• The MSEPUB database was updated to match the ESP code. See Databanks

The Gibb's Free Energy Minimization Initialization routine failed to mass balance if the result was all vapor. This has been fixed

When performing a survey for a pure component, such as the boiling point pressure of pure water v. Temperature, a flag was incorrectly set to suppress initialization. This resulted in an all vapor point. This flag is now correctly set.

OLI Security module updated to allow for 64 bit operating systems.

Gibb's Free Energy of Minimization Initialization was enhanced to protect against multiple root answers

All Products

Rates of corrosion were calculated incorrectly in builds 2.0.40 and 2.0.41. This was corrected in this build.

The creation of the model generation LOC file (a textual description of the thermodynamic model) has been added for users with FULL ACCESS rights. This file has been available in ESP for a considerable time. This file will be temporarily stored in the windows temp folder.

The DBS file viewer plug-in has been updated to read the LOC file if available. To save the file, the user will have to copy/paste the text to a new file.

Calculation icons were added to the tool bar for single point calculations

Sulfur REDOX was changed to include a new species HSO5-1. This species was not parsed correctly in the REDOX subsystems which made sulfur non-selectable. This only affected build 2.0.41

All Products

The Mixed Solvent Electrolyte (MSE) Public (MSEPUB) and the aqueous PUBLIC databases have been updated. Support for MIXSOL (the hydrogen ion MSE database) has been dropped

Some files will not open correctly with earlier builds because of the new Gibb's Free Energy Section. This version has been fixed so that old files will open.

All Products

• The Gibb's Free energy and entropy of each species can now be calculated for each phase. This is an option under Calculation Options found in the Tools > Options menu item.
• A remove options was implemented for plots. You can now right-click a curve on the plot to remove it from the plot. This differs from Hide since it does not appear in the data set.

MSE

A check for the presence of a "Water-rich" phase (usually referred to as the aqueous phase) was based on the activity of water being above 0.8. This caused dual answers for phase behavior depending on the initial value for water activity. This check has been removed and now the amount of dual answers for phase behavior has been reduced.

All Products

• The solvers and databases were updated to match the OLI Engine. See the following Release notes:
  • OLI Engine
  • OLI Database
• Added Feature
  • On plots, you can now right-click a curve in a plot and hide it. This can make the plot easier to read. To unhide the curve, you must use the Curves button and uncheck the hide box for each curve. This feature does not work with the Dominant Species curve selection.

All Products Serialization (saving and opening of files) enhanced to clean up bad calculation objects possibly created in old versions.

Corrosion Analyzer When a Pourbaix diagram is invalid, the dump file was assigned to a duplicate file identification number. This could cause a hard crash. The identification number is now as singed to a unique number.

Corrosion Analyzer Elemental sub-systems not assigned to metal allow were not displayed properly on the Pourbaix Diagram. You can now select sub-systems for superimposition that are not part of the metal.

Corrosion Analyzer: A problem in the alloy manager was detected. Not all the alloys for Pourbaix diagrams were incorporated into MSE.

MSE: Carbon was left out of the database. This has been added.

Corrosion Analyzer Pourbaix diagrams occasionally did not display the correct "Contact Surface" when selected. This occurred when the MSE Public database was installed. Material codes from the MSE database conflicted with material codes in the standard database and those conflicts resulted in an incorrect diagram. This has been resolved.

Corrosion Analyzer Pourbaix contact surfaces in the aqueous model may have a different OLI Tag name in MSE (such as phosphorous: AQ=PEL, MSE=P4EL). If models are switched from the aqueous model to MSE, such contact surfaces must be first deleted then re-entered.

Variable name maps were misaligned when removed using new compiler optimizations. The removal of variables due to small values has been fixed.

General update to security system to allow for more licensing options.

The cursor now appears correctly in the input grid in Japanese versions of Windows XP2

(MSE) The problem of multiple root in LLE simulations has been corrected.

Repeated deleting of objects in the tree-view may result in an invalid child object being created. Code was added to prevent this from occurring and to repair any older version files that may be re-opened.

Names dictionaries are now properly imported. Previous builds failed to make the import permanent.

2..0.31

Using a letter such as "b" to set a pressure unit to bar would result in a crash of the software. This has been fixed.

Help file has been completed.

Can no longer select an MSE database unless a valid license for MSE exists.

Modifications to the report are now preserved when saving the file.

Long file save times and CPU usage after the application exited have been fixed. This was cased by custom units being applied to a saved table for each object each time the program was saved. The amount of memory required went up as the square of the previous memory. This has been corrected.

The install program will now read your existing serial number and use it during the install. No longer is there a need for you to have your existing serial number on hand when using the repair feature of the install

Removed stray reconciliation messages from summaries and reports in the Score Analyzer

Removed calculation buttons from the main stream dialog and replaced with a drop-down button. This drop-down button contains all the calculations available for this stream.

The routine to calculate the margins of the report was upgraded to allow more complicated formula names to be properly displayed.

The filter tag for reports has now been added. You can tell what you have set as a filter.

Pit current density unit tag can now be changed from the master units dialog.

Non-metallic elements added so they can now be displayed in Pourbaix diagrams. They are not available via the contact surface drop-down box and must be entered manually.

The legend in plots will now properly print to printers and PDF files.

 Score Analyzer would fail when reconciling a brine. This was caused by the chemistry model generator being called at the wrong time. The various chemistry models used in Score were out of synch. This has been corrected.

Activity coefficients are consistently reported now on a mole fraction and molality basis for both the MSE and aqueous models

 Metals table in Analyzer updated to include all elements in PUBLIC to be tied to both MIXSOL and MSEPUB. Fixes a problem where you could not select some elements as contact surfaces in Pourbaix diagrams.

 Units selection for vapor target in composition calculations were corrected.

Solids selection in the Chemistry > Model Options > Phases tab have been reversed. By default, active solids are checked to indicate that they are available to form. Unchecked solids may have their scaling tendency calculated but they are not mathematically available to form.

When plotting material balance groups, a display name error was discovered. The actual material balance code (e.g., Na = 3) was displayed instead of the name. This was corrected to show the name of the material balance group instead of the numeric value.

Lab Analyzer files can now be opened directly in Stream Analyzer. The file will be saved as a Flamboyantly file if the original file had the extension LAA.

Corrosion Analyzer files from 1.3 may have had some objects deleted but still in the file. Opening these files in 2.0 may cause crashes. Protection code was added to look for such lost objects.

The concentrations of species for the 2^nd liquid phase in mole percent units now sum to 100 percent in the apparent species view.

 Units selection for vapor target in composition calculations were corrected.

Pit current density will not be reported in CA when there is no localized corrosion (issue # 795)

Corrosion rates will not be erroneously calculated using the MSE model (issue # 796)

Selection of plot variables for the Y and Y2 axis scales in CA has been fixed (issues # 758 and 776)

More protection has been introduced to stability diagrams to prevent crashes, especially for cases with a large numbers of species (issues # 753, 754)

Fixes for importing .SMP files into the Analyzer
