SIM Suite Reactors Models - EBR-SIM

DefectDescription
17403Add Collaboration tool feature to EBR-SIM
16880Catalyst Makeup Rate has the wrong varID in WB/KB

SIM Suite Reactors Models - FCC-SIM

DefectDescription
17692CDB: FCC allows to select the catalyst but it deletes the file before reading it on calibration
17521FCC Monitor Reactor fails while migrating an UMT to v7.1
16970FCC-SIM: ZSM5 factors not updated if next to the identifier there is something written
14709To allow the new ZSM5 v7 kinetic method work even if reactor dilute phase V is empty or zero
12045Missing Sulfur content in all products results in -32767 passed in FXDATA and calibration failure

SIM Suite Reactors Models - HXX-SIM

DefectDescription
17725HXX: Deprecated reactor-wide cracking selectivity factors showing up in Application Workbook
17559HXX: Pressure drop cat shape *actually* erroneously swapped “sphere” vs. “cylinder” this time
17436Sulfur Imbalance in NHTR-SIM
17390HCR 2-Stage without liquid recycle to R3 caused internal crash
17222CNHTR-SIM Sulfur Shift reactor generates large positive net yield for Mercaptan Sulfur
16861HXX pressure drop mistakenly error out when R1 tops cat height is larger than R1 B1 cat height
16859Calibration falsely failed due to division by zero within the pressure drop code
16824Division by zero causes unexpected error of flash h2 in liq goes NaN
16787Poly-aromatics rector validation step prevents calibration
16746CNHTR-SIM S/N override only works for 2rx config (diolesat/deS) but not single-rx (selective hds/sulfur shift)
16720HXX: Error #125 for heat balance problems obscures real cause of calibration failure
16718HXX: Error #47 blames the wrong reactor and bed for data issues
16717HXX: Crash when new quench control enabled and # of R2 beds exceeds R3 beds
16646Cold predict failed even though calibration/back-predict/primed-predict succeeded with the same input data
