NHTR-SIM™

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 trying to understand the impact that silica poisoning will have on catalyst deactivation? Are you concerned with how operation of the hydrotreater will affect downstream processing units?

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

NHTR-SIM has been used successfully to:

• Generate and maintain LP vectors
• Analyse impacts of operating changes on performance
• Optimise unit operation against real constraints
• Track and trend unit performance
• Determine hydrogen demand for changing feedstocks

NHTR-SIM can be used in standalone mode to investigate the performance of the hydrotreater unit in isolation, 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.
