SIM-Suite Models | DC-SIM™
Are you trying to understand the impact of changes in residue on liquid product yields and coke properties? Are you concerned with how to minimise furnace fouling to maximise furnace run lengths? Are you trying to understand the impact that different operating pressures and temperatures have on product yields and qualities of changes? How do you determine the optimal recycle rates?

KBC’s DC-SIM has been used worldwide for over 20 years to help refiners just like you to answer these and many other questions. DC-SIM lets you examine the effect changes in operating conditions, feed rates, feed qualities, and recycle to feed ratio have on yields, product qualities, and cycle lengths.

DC-SIM has been used successfully to:

  • Generate and maintain LP vectors
  • Analyse the impact of process changes on performance
  • Optimise unit operation against real constraints
  • Track and trend unit performance
  • Determine alternate operating strategies


DC-SIM can be used in standalone mode to investigate the performance of the coker unit in isolation 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 coker unit on the entire refinery performance.
