FEATURE: Please provide a manual sorting option for the Conditions tab in the Scale Scenario object.   Temperature and pressure do not always change in a single direction during production and so this feature will help in those cases, if a client needs to add additional points to their calculation.

User can right click the mouse on the location grid to rearrange the condition order by manually moving a row up or down.

Since ScaleChem-Standard is no longer being distributed, we need a method to convert the SCA files into OAD files without launching ScaleChem.

Reduced ScaleChem Standard to a dll with no user interface to enable file conversion without ScaleChem Standard installed

We need the capability to plot both the varied brines which go in the mixing waters. This is under Mixing Water -> variables -> Varied Brine

This is fixed and either Brine can be used as the plot variable. Also user can select either Ratio or Flow as the unit on the plot.

The inflow composition for the set pH is fixed at 550000 ppm CaCl2, 580 ppm FeCl3 and
398 ppm CaOH2.    This amount of CaOH2 is about what is needed to achieve a
4 pH.

Please look at the Output tab, and you will see how the inflows have changed.

Next, look at the survey, since this is where the problem is most severe.
It is a CaCl2 survey from 0 to 550000 ppm CaCl2 by 10,000 ppm increments.
The pH is fixed at 4 .  The plot is total dissolved Fe vs. CaCl2 inflow. 
You will see that the recombining of the inflows skewed the CaCl2 in values – the balance of the CaCl2 inflow is converted to CaOH2 inflow

This was fixed prior to the final release of 9.5.3.

If a user tries to add a volume % or Temp value on the assay screen first instead of typing the component name, and then tries to add the name, the screen does not refresh automatically. Vol and temp table should be greyed out till an assay name is added.

This is fixed and will behave as follow: (1) If the Assay name is blank, the distillation table is locked and can't accept any input. (2) When a valid assay name is given, the blank row on the distillation table is displayed and user can enter data. (3) if the assay name is deleted all rows on the distillation table are removed and the table is locked. (4) Only one assay is allowed in Oil. This was not enforced before the fix, and it is now. (5) Before the fix if you enter Vol/Temp first and then enter an assay name, all controls are still disabled. It is fixed now.

4638 16145 Stream Analyzer

Water Analyzer file. Worked in 9.5.2 but fails in 9.5.3 with The FORTRAN failed to obtain requested double data.

This is caused by the first survey point setting the composition to 0 reducing the number of kvalues (NKA), KValues need to be returned based on NK

K-values are now returned based on AKNAMEO orders and a total of NK. The K-values are zeroed if these can't be extracted from the AV vector (e.g., AV vector doesn't have it).

The report does not total Ce(+4) correctly in the MBG section. Part of the solid mass is missing for one of the hydrates. There may be other issues with MBG reports

This was a result of a database import issue (OLI Studio only). The MBG values are calculated by OLI Studio using the stoichiometric values in the database. However, the access import routine was inferring the data type incorrectly because 1.0 was shown as 1 and it considered it an integer. So the CEO2NIT.9H2O had a stoic of 0 for Ce which should have been 0.7. Updated the import code to correctly handle exporting 1.000 as 1.0.

The pST setting in the global scalechem calculation options does not pass down correctly to 4 scale chem objects, namely, Scenario, Saturator, MixingWater, and Facilities. pST in these objects are always turned on; however, the method (Estimated or Rigorous) selection is honored correctly.

A file was forgotten to be checked- in (ScaleAnalyzerMessageHandler.cpp) when Bug#3767 was resolved back in April.

I am working on the new V9.5.3 features/functions and noticed that the
Copy option for the plot has changed.   I am specifically referring to the
dual survey calculation.

This is what existed in V9.3.2 (and probably V9.5.2)

  • When copying from the Plot the pasted values were in an x-y matrix where x is the first survey and y is the second survey.
  • When selecting the View Data button, the data was in an array where the x was repeated for every y. 

It appears that in the new version copying from the Plot view creates the array and no longer the matrix.   If I save to a CSV, the matrix view is preserved.

Please change the Copy from Plot view back to the matrix or confirm that the matrix copy is still there.

The default copy mode was changed and checked in by mistake, it is controlled by a registry key so you can add the following registry key and set it to false to get back the previous behavior.

Under
HKEY_CURRENT_USER\Software\OLI Systems\OLI Studio 9.5\OLIStudio\Settings

Water Analysis: Added/removed CO2 not displayed in summary section, present in output grid

Several issues have been resolved in the fix. (1) In void
StreamAlkalinityDlg::OnOK() we must call m_pAlkData->setUseSingleTitrant before calling m_pAlkData->setAlkalinitySpec, so in AlkalinityData::setAlkalinitySpec PHTitrantAcidTag, PHTitrantBaseTag, and m_pUcvSingleTitrant will be correctly assigned. Otherwise switching to single titrant will have problem. (2) getAddedAlkTitrant is implemented so the CO2 can be displayed in the summary pane. (3) ReconcileCalc under Brine may not display the added/removed pH titrant correctly. This is due to the Brine's ReconcileCalc only has a work stream (no result stream). To resolve the problem, the function GetAddedValueAsString() is replaced with
getAddedValueAsString() and it uses s_csAddedSingleTitrantTag instead of using diff between inputStream (work) and outputStream (result).

CRASH: Model generation after Save As Stream. Case was using surface complexation species.

Surface Complexation generates species that do not exist in the chemistry model. When doing "Add As Stream" these species should be removed from the newly created streams. Also if Surface Complexation is used, user cannot draw off any phase during "Add As Stream".

Water Analysis: Single titrant pH reports default titrant in report. I used CO2 to reconcile the pH But on the Report tab, HCl is mentioned. The mg/L value is the same.

This is related to Bug#4648. When using a single titrant other than the default HCL or NaOH, the new titrant is stored in m_pUcvSingleTitrant correctly (fixed in Bug#4648). However, when loading a saved case with incorrect single titrant stored, it is not changed to the correct one during file loading. It is now fixed in the serialization.

More fix. If m_pUcvPHTitrantBase in Serialization is not the same tag with m_pUcvPHTitrantAcid (single titrant mode) due to previous version, we must use m_pUcvPHTitrantAcid tag for m_pUcvPHTitrantBase  and m_pUcvSingleTitrant.

A user is reporting that the first two objects in a file are locked and cannot be edited.  The objects cannot even be renamed.

In this case a gas object fails to converge when using H2O saturate option. I think this is an initializer issue. See the object (Use this).

I simulated the H2O saturate by running an H2O composition survey. With Restart=OFF there are many all vapor points which is probably unrealistic with the moderately heavy hydrocarbons.

With Restart=ON the plot is much more realistic

Two separate issues have been fixed:
1) Phase checks have been added for gas stream saturate with water.
2) Re-initializing after variables are bounded.

ScaleChem: Drag and drop into a saturator natively selects a brine instead of whole fluid

When drag drop a Saturator to a Scenario, Saturator, or Facilities grid, it will first be considered as a Whole Fluid inlet. However, when drag drop a Saturator to a MixingWater, if either of the 2 brines is empty the Saturator will become one of the brines. Otherwise the Saturator will become a Whole Fluid.

PLOT: The Y-axis is set for auto scaling for min and max.  The actual min/max of the data does range from 1.2 to 4.2 and this is the scaling in the Y-axis properties dialog. The major and minor units are 5.0 and 0.0.  This is not reflected in the auto scaling which are 1.0 and 0.5 respectively (you need to put the diagram at full screen).

Updated Minor tick Unit to be actual value not number of tick marks between major tick marks.

When investigating a solubility case we found that a composition survey does not converge all the points in the middle of the calculation.

The AQ phase is a constant composition and each point should converge.

FEATURE: Might we have a conditions tab for the Facilities, where the information, Node Name, T, P, Inflows, and Sep phases are displayed. It would be used in place of the node editor for names, condition, and separations only.  it's a faster way to review what was entered.

A new vertical tab "Conditions" is added to the Facilities. This tab shows a summary view of all the nodes including node name, number, temperature, pressure, drop solid, etc. User can use this tab to add a new node, remove a node, change T or P, and change drop solid option.

The solver becomes very slow (or does not solve at all) when adding a
minute amount of H2S to the stream. See the “BP curve” survey. It readily solves with H2S = 0, but not with H2S = 1e-6

Confirmed: In the attached file (look for the USE This!) tag, when H2S = 0 the run time is about 3.6 seconds.  With 1.E-06 moles H2S the run-time is well over 1200 Seconds.  It seems to be stuck on a phase check for the second liquid phase.  No such phase exists when H2S = 0.0.

It could be that the H2S - Hydrocarbon interaction is incorrect.

Tested with latest development engine after h2s set to 1.0e-6 survey calculation time was 4.065 seconds with 0 h2s calc time was 3.846 seconds

Please calculate the set pH single point using different volumes, 0.001 m3, 1m3, and 755 m3.  Please look at the NaOH added in the Summary section. There is a multiplier factor that increases the concentration of NaOH used that is linked to the Stream Amount volume entered.   The report shows that the identical amount of Na+1 exists in the water regardess of the volume, so the actual flash calculation is fine.

Engine calculates the molar amount needed (mol/hr) correctly. Report and summary are currently not supported to exhibit in molar concentration unit (mol/L).

Option to allow facilities calculation to continue if alkalinity calculation fails.

This needs to be addressed in the Engine, EQALK needs to continue on if Alkalinity calculation fails, and report back that the alkalinity calc failed. By return the Big number value returned by calling EQSOLD ID=501.

The case will still fail as the reason for failure is not connected to the fact that the calc alkalinity was turned on. But a warning will be issued if Alkalinity calculation fails and the calculation will continue.

Solver issue, incorrect phase behavior for amine splits. This seems to be a solver issue and not a databank issue.  The melting point of MEXHCL is approximately 85 C in the databank and the solver predicts 90 C.  In this case, the survey with Restart=Off has some stray MEXHCL solid above this temperature. This is unlikely to happen. A liquid phase perhaps but not a solid.

If you run the case with Retart=On (also in the file) we get a much more reasonable phase transition.

Phase inclusion/exclusion check was updated.

Would someone confirm that the minor tick marks work on the plot.  I just tried it on this file (0.5 pH unit tick marks) but the value resets to zero and the marks do not appear.   If I use a whole number, 1 for example, it works.

Confirmed.  In the attached file I cannot set the minor tick mark unless I also set the min/max to manual. Even If I do that when I come back to the plot options. Everythying is set back to the default values.

Please look at the concentrations of NH42CO3 and NH4HCO3 are 3286.1 and 7826.3 mg/l, respectively.   The stream amount is 100 ml. If I change the inflow units to Molar concentration, THEN change them back to concentration, the resulting values are 10x smaller, 328.6 and 782.6 mg/l.

If I use a stream amount of 10 ml, the problem does not occur

Scaling tendency value difference due to the scope of access of serial number. In a case file, CaCO3 is chosen as precipitating solid. While there is no solid CaCO3 formed, its post-scaling tendency = 1.00002 Isn’t this a bug?

The previous encryption caused a slight change in numbers during encpytion->decryption. This was fixed by adding a new module that encpytion->performs a lossless data encryption/decryption method by manipulating the strings read from the .dbs file instead of numbers.

Please turn on heat capacity properties from calculation options for the brine, gas and the saturate object.Then calculate again and it fails.

This is not related to Heat capacity. One of the main problem that we realized that in this file, the saturator is trying to precipitate the two solids , CaCO3 and CaSO4, which have a big difference in the solubilities.  If you select CaSO4.2H2O, gypsum , then your case should converge consistently.

Tested in latest development build now runs fine.

Difference in contour plot for two files with same numbers. For the same numbers for the objects the dbs are compared, the contour plot though similar, one point fails.

This is a result of Heat Capacity/Gibbs/Entropy being calculated in one case and not the other. If they are turned on the results are the same. The source inlet (Saturate) has the same issue but does not appear to impact the contour.

Inconsistent phase behavior with a amine like case. The "liquid 1" line keeps vanishing and at some point the vapor line has a bump - this calculated with RESTART=OFF.  When RESTART=ON, the lines are smooth.

Phase existence issues with sublimination. What we see moving from low temperature to high is a VLE phase, then a SVE phase (sublimation) with some non-converged points, then back to a VLE region back to a SVE region.  Looks very unstable.

Is it possible to put a material balance table at the top of the report for the ScaleChem calculations, Facilities, Saturator, Scale Scenario, and contour?

For ScaleChem Studio calculations (Scenario, Saturator, MixingWater, and Facilities), a mass column is added to the Inlets Summary table of the report to show mass from each inlet. In the Stream Properties table a total mass row is added at the bottom of the table. In the Facilities report a new section (Mass Balance Summary) is added and the default is off (hidden). This section has a table showing the mass balance across all nodes and all external objects used in the Facilities. To see the newly implemented mass features, user may need to do a calculation if an existing case saved by early version is loaded.

pScaleTend not the same when solids turned on and off when calculating a non-isothermal object (such as dew point).

The current algorithm for PScale Tendency in the Solver works for TP flash.
The idea of pScale is to calculate scale tendency before solid phase is introduced in the process of convergence at fixed T and P.

Since this case is a flash calculation of fixed P and vapor fraction, the resultant T will be varied from the initial value. However the pScale is calculated based on the initial T, rather than the final resultant T. the pScale cannot be calculated at the final T since at that time, the solid phase has already introduced. Speciation and activity coeff. of the system are not the same as before the solids are introduced.

Solver will issue warning message if the pScale calculation T&P is different than the final conditions.

Once user click any data raw the Tab will follow the requested order. All ScaleChem grids serialize the current cell location, so if user click on certain cell and click other object and comes back the cell will remain at user's previous selection.

Current tester can only turn on/off the entire subsystem. Some MSE cases require turning on the subsystem with some valences being off within the subsystem.

Tester can further select which valences under an enabled subsystem being off.

Autoclave calculation fails. Errors about zero'd inflows. OUE file has a lot of NaN values.

Initial estimates have been provided to the solver at the expense of calculation time. This may result additional cases to converge. In any case the estimates are unsatisfactory, the solver will proceed as it was before.

However, total calculation time will increase for the estimation step.

REPORT: Reconciliation report incorrectly reporting total volume of aqueous phase.

The water value in the report is now showing the Aqueous phase instead of the total. Also fixed is the alkalinity row where Measured should reflect the user input value even if the alkalinity is not reconciled. The difference column and the unit header row are removed. If both measured and calculated alkalinity are 0.0 then don't show the row.

Add a stream ->Add HCL -> 1mol -> MSE, turn 2nd Liq on -> Add a single point isothermal calc -> Calculate -> Add a survey -> Add second variable as Pressure -> Calculate -> View plot -> click on Contour -> It will say that the selected data cannot be plotted as a contour -> go to variables -> Add pH ( or any other variable you k now works for contour) -> click view data -> click contour again -> Crash.

Fixed issue with a pointer not being correctly handled when deleted.

The two ionic strength variables are indistinguishable – is it possible to change the names to 

Ionic Strength – Liq1 (mol/mol)
Ionic Strength – Liq1 (molal)

Or something like this


Also, are we willing to truncate Strength to Str. And are we using Liq1 or Aq into the future?

The code to update the pressure range was updating the temperature range in certain cases. Refactored code for rangeAdded (m-based) and (x-based) to Ionic Strength namesupdating to fix the issue.

Is there are way to create a report of OLI Stream Analyzer’s assumed species MWs?   We wouldn’t need all the species, but a subset that are of interest for one of our projects.

The molecular weights are added into the Speciation Table and the format of the table is modified. Species names will be on the left column and each phase will be a new column.  An "X" will mark the associated phase
column(s) for a species if it exists in the phase(s). User Inflows and Related Inflows columns are removed; however, if a species only exists in the User Inflows or in the Related Inflows, it will be displayed with no "X" on any of the phase column. On the other hand, e.g., if a species only exists in the Vapor phase, and the Vapor phase is turned off, the entire row for the species will be hidden.

Delete a calculated brine may cause incorrect reference count. Map still has the brine as well as its ReconcileCalc. Another issue is that after a brine calculation the engine is not unloaded since Brine is set as a ResultCalc. This may cause a heap corruption.

For the reference count bug it is fixed by overriding the
prepareForDeletion() in Brine and clear the result and the ReconcileCalc before calling base's prepareForDeletion(). For the heap corruption bug a temporary workaround is adding a transition Boolean t_bCanUnloadSolverForResultCalc in ScratchPadCalc and have Brine and other ScaleChem objects setting it true before calculation.

When a Facilities contains assay generated pseudo components, the calculated state in certain node(s) may get cleared after save and open.

This is due to the Bug#3097 fix that assay generated PCs were removed from the input stream's user inflow as well as the chemistry model. In Facilities we use a global chemistry model and each node may have different species. Thus the node(s) with assay generated PCs being 0.0 will have these PCs removed during Stream::postSerialization() and the calculated state is cleared. It is now fixed that PCs with zero values can be removed only when the associated assay exists in the user inflows.

When the user changes the inlet type on an existing inlet in the grid, if the existing provider can fulfill the new type then the name of the provider should remain in the inlet name cell.  Current version automatically deletes the existing inlet name and requires the user to enter a inlet name.

The existing inlet will stay if it can provide the new type that user selected.  The other fix is that inlet type dropdown list will include types regarding the current provider-receiver relationship. For example if
Node2 is taking WF from Node1, then BrineFrom, OilFrom, GasFrom are available types when user click the dropdown list on the WF from cell. This is because these inlet types are inclusive in the WF from inlet type.
