Petro-SIM 7.6 Changes to Refinery Reactors

Petro-SIM 7.6 introduces key improvements and added capabilities to the Reactor Suite to keep up with the demands in the industry, including technical improvements to our hydroprocessing reactors and furnace models

Key Highlights

  • Renewables DHTR-SIM:Separation of the renewable reaction kinetics to improve TGL hydrocracking selectivity
  • Renewables DHTR-SIM and HXX-SIM: Enhanced liquid reycle ( internal & extrenal) handeling to isomerization reactor.
  • Renewables DHTR-SIM and HXX-SIM: Added capability for external gas quench to any reactor bed.
  • HXX-SIM: Use Feed SG and k factor (modified) method added in the Feed characterization.
  • FCC-SIM: Enabled oxygen balance in FCC to support co-processing.

HXX-SIM

DHTR-SIM (Renewables)

  • Separation of the renewable reaction kinetics (decarboxylation, decarbonylation, and hydrodeoxygenation) as their own separate reactions to be able to achieve rigorous modeling of the response of TGL hydrocracking selectivity to changes in operating conditions.

DHTR-SIM (Renewables) and HXX-SIM

  • Improve handling of liquid recycle (internal and external) to Isomerization reactor by improving its composition convergence criteria to consider Core iso-paraffins in addition to Ca,Cn. *Improve initialization of liquid recycle composition loop overall helping solve times to reduce by ~ 30% (applicable to overall HXX)
  • Handling of external gas quench to any reactor bed.

HXX-SIM and Synthesis

  • Use Feed SG and k factor (modified) method added in the Feed characterization methods list for HXX to take into account Sulfur, CCR and cracked feed type variability. The same was enabled in the synthesis oil settings to work at flowsheet level.

FCC-SIM

  • Enable Oxygen balance in the FCC GUI for assessing increased load of inerts in the FCC overheads when co-processing bio-oils.

DC-SIM

  • Addition of CA/CN information to the DC outlet streams to help with routing of DC streams to other unit.

REF-SIM

  • Improving the coke on catalyst response especially with feed composition change.
