<b>Hydrotreating process</b>
SIM Reactor Suite | VGO HTR-SIM™

Do you target maximum aromatic saturation or final product sulphur when determining operating temperatures in your hydrotreater? Are you trying to determine how a particular feed will affect catalyst run length? Are you hydrogen constrained and need to understand the real hydrogen demands within your refinery? Are you concerned with the impacts that changes in your hydrotreater will have on downstream units?

KBC’s VGO HTR-SIM has been used worldwide for over 20 years to help refiners just like you to answer these and many other questions. VGO HTR-SIM lets you examine the effect changes in operating conditions, feed rates, feed qualities, and recycle cut point have on yields, hydrogen consumption, and catalyst run length.

VGO HTR-SIM has been used successfully to :

  • Generate and maintain LP vectors
  • Analyse what if scenarios
  • Optimise unit operation against real constraints
  • Track and trend unit performance
  • Analyse hydrogen demand for changing feedstocks


VGO HTR-SIM can be used in standalone mode to investigate the performance of the hydrotreater unit in isolation, in conjunction with FCC-SIM, KBC’s fluidised catalytic cracker model, to investigate the tradeoffs between the operation of these two units in conjunction with each other, as part of a hydrogen management study with other hydrogen producing or consuming units, 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 hydrotreater unit on the entire refinery performance.
