4443 | 15529 | API I have another question regarding the OLI Engine Developer Edition. I am trying to display Keq values from the OLI calculation in the Excel sheet. I can understand most of the Visual Basic code in the Excel32bitEngineAPISample file that come with the developer edition and made modifications to it. So far I am able to populate the components for Kvalues in Excel, but the Kvalues displayed from the result stream are all zeros. It is possible that I made some error in the code, but I would like to know: (1) if the developer edition support calculation of Kvalues. I would assume yes since there is a variable defined as OLIKValues = 8 in the OLIEngineAPI. (2) if the function OLISolveIsothermal from "OLIEngineAPI.dll" library computes Kvalues. Or is there another function from the library that computes the Kvalues Added support for KValues |

3579 | Strict security must be implemented on the engine side for various products, especially those which can be run easily through command line. Security has been enabled for all standard products. This includes login/logout and security checking in-between critical computations. All procedures can be found under security.for under module in engines solution. |

3596 | ETHEGLYCOL and pseudocomponent UNIQ interactions and mutual solubility parameters will be added. ETHEGLYCOL and pseudocomponent UNIQ interactions and mutual solubility parameters have been added in the Engine (MSE only). The parameters were developed by Peiming Wang. |
OLI | PK | |||||
3612 | Recent data work for high pressure methane in hydrocarbons requires new interaction data for methane with pseudocomponents. Added UNIQUAC (UNIQ), pressure dependent UNIQUAC (PR-UNIQ) and SRK interaction parameters between methane and pseudocomponents in the Engine for use in the MSE Framework. |

3485 | 13406 | Incorrect phase equilibrium with new databanks using pseudocomponents This phase behavior problem was due to not including pseudo component in the special algorithm. This was fixed by adding the pseudo component material balance code in the inclusion check. |

Bug ID | Description | |||||||
3308(13034) | Inconsistent phase behavior with organic liquid and REDOX. An error in the derivatives for redox equilibrium reactions was corrected (RDY) |
|||||||
3312 | Thermal Conductivity Update Thermal conductivity calculation has been updated. This update is for version 9.2 (dbs version 17.3). 1) We have renamed the existing thmpar.dat file in our databank to thmpar2.dat. This is because there has been a major change in the number of interaction parameters between species. So, accessing the old thmpar.dat with the updated engine will result in erroneous calculations. 2) Updated engine will look for thmpar2.dat only. If thmpar2.dat is not in your databanks (which is the case using older databanks), we won't calculate thermal conductivity and flag appropriate warning message. 3) However, if the users turn-off thermal conductivity for his/her calculation, we won't flag any warning even if the thermal conductivity is not calculated due to not finding the thmpar2.dat file. 4) Mass transfer column calls eqprop directly for thermal conductivity calculation. For mass transfer column, if liquid phase thermal conductivity is not found or not calculated, it returns 500. (PK) |
