VIS-SIM™

Do you struggle to determine the optimal set of operating conditions to achieve the highest conversion while still making a stable fuel oil product? How do you manage the performance of your furnace? Do you have concerns with regards to furnace fouling? Are you trying to increase your furnace run lengths? Are you trying to predict key properties for your visbroken tar and determine how operating severity and feed quality affect these properties?

KBC’s VIS-SIM has been used worldwide for over 20 years to help refiners just like you to answer these and many other questions. VIS-SIM lets you examine the effect changes in operating conditions, feed rates, and feed qualities, have on yields, product stability, product properties, and furnace run length.

VIS-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
• Improve furnace run lengths

VIS-SIM can be used in standalone mode to investigate the performance of the visbreaker 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 visbreaker unit on the entire refinery performance.
