List of bug fixes included in this service pack
SIM Suite Reactors Models - AROM-SIM
| Defect | Description |
| 17192 | Unresolvable inconsistency errors loading 62 AROM cases into 71 |
SIM Suite Reactors Models - DC-SIM
| Defect | Description |
| 17433 | Default Ca Cn Estimation Method not ideal in Coker Synthesis settings in wizard base case |
| 16793 | DC-SIM returning different results based on feed stream order when non-Tray 1 feeds present |
| 15688 | The report of drum vapor to fractionator inlet temperature is wrong when no quench is applied |
| 15314 | The sulfur and nitrogen contents in feed 6 are not counted in the S and N balances |
SIM Suite Reactors Models - EBR-SIM
| Defect | Description |
| 17403 | Add Collaboration tool feature to EBR-SIM |
| 16880 | Catalyst Makeup Rate has the wrong varID in WB/KB |
SIM Suite Reactors Models - FCC-SIM
| Defect | Description |
| 17692 | CDB: FCC allows to select the catalyst but it deletes the file before reading it on calibration |
| 17521 | FCC Monitor Reactor fails while migrating an UMT to v7.1 |
| 16970 | FCC-SIM: ZSM5 factors not updated if next to the identifier there is something written |
| 14709 | To allow the new ZSM5 v7 kinetic method work even if reactor dilute phase V is empty or zero |
| 12045 | Missing Sulfur content in all products results in -32767 passed in FXDATA and calibration failure |
SIM Suite Reactors Models - HXX-SIM
| Defect | Description |
| 17725 | HXX: Deprecated reactor-wide cracking selectivity factors showing up in Application Workbook |
| 17559 | HXX: Pressure drop cat shape *actually* erroneously swapped “sphere” vs. “cylinder” this time |
| 17436 | Sulfur Imbalance in NHTR-SIM |
| 17390 | HCR 2-Stage without liquid recycle to R3 caused internal crash |
| 17222 | CNHTR-SIM Sulfur Shift reactor generates large positive net yield for Mercaptan Sulfur |
| 16861 | HXX pressure drop mistakenly error out when R1 tops cat height is larger than R1 B1 cat height |
| 16859 | Calibration falsely failed due to division by zero within the pressure drop code |
| 16824 | Division by zero causes unexpected error of flash h2 in liq goes NaN |
| 16787 | Poly-aromatics rector validation step prevents calibration |
| 16746 | CNHTR-SIM S/N override only works for 2rx config (diolesat/deS) but not single-rx (selective hds/sulfur shift) |
| 16720 | HXX: Error #125 for heat balance problems obscures real cause of calibration failure |
| 16718 | HXX: Error #47 blames the wrong reactor and bed for data issues |
| 16717 | HXX: Crash when new quench control enabled and # of R2 beds exceeds R3 beds |
| 16646 | Cold predict failed even though calibration/back-predict/primed-predict succeeded with the same input data |
SIM Suite Reactors Models - OLEFIN-SIM
| Defect | Description |
| 17574 | Pyrolysis furnace Hydrotreated Gas Oil gives invalid feed composition error |
| 17501 | Furnace handles gas oil incorrectly in split coil case |
SIM Suite Reactors Models - REF-SIM
| Defect | Description |
| 17595 | REF: The range suggested in the yield test warning message may not be accurate for some severities |
| 16263 | Need to update the Ref-SIM manual for calibration |
