SIM Reactor Suite | FCC-SIM™
Are you air blower constrained? Wet Gas Compressor Limited? Are you trying to determine the optimum riser outlet temperature to maximise conversion? Are you trying to determine the right catalyst to run in your unit? How about additives? Are you regenerator constrained? As feed rate and qualities change, how do you ensure that you are operating the unit at the right constraint to maximise the operating margin of the unit?

KBC’s FCC-SIM has been used worldwide for over 20 years to help refiners just like you to answer these and many other questions.


FCC-SIM has been used successfully to :

  • Generate and maintain LP vectors
  • Analyse the impact of changes in feed and operating conditions on unit performance
  • Optimise unit operation against real constraints
  • Track and trend unit performance indicators
  • Study the impacts of different types of catalyst and additives on product yields


FCC-SIM can be used in standalone mode to investigate the performance of the FCC unit in isolation, in conjunction with VGO HTR-SIM, KBC’s gasoil hydrotreater model, to investigate the tradeoffs between the operation of these two units in conjunction with each other, or as part of a refinery wide model that investigates the complex relationships between different processing units and the macro effect of changes in the FCC unit on the entire refinery performance.
