• No predictive view of
performance for current
operations
Troubleshooting
• Data analysis only on
specific trends of the data
• Ad hoc simulations
Planning
• Compiling and reconciling
performance data
• Error identification and
time for LP model updates.
Reporting
• Data gathering and

US$0.05 – 0.10/bbl for ensuring that the LP is an
accurate representation of the refinery
Value of monitoring
via a Digital twin
Up to US$0.05/bbl for unit monitoring, including:
Faster response to/recovery from upsets
Remaining on plan – identifying issues and resolving
them before operation becomes constrained
Identifying improvements to realise increased value

12. Implemented at
Gulf Coast refiner
Identified opportunities of
$8 million in first 6 months.
Rationalized and corrected
yield accounting and unit
material balance.
Advanced analytics helped
increase uptime of key
process equipment
Case study 1

13. Case study 2
US Refiner with 12+
refineries worked with KBC
IT and Modelling services to
roll out unit health and
model monitoring
applications on nearly all
their process units.
Whole program executed in
just over two years
Uses Petro-SIM & PI
architecture
Refiner modelling team &
SMEs defined KPIs
Worked with KBC team to
speed up deployment
across multiple units

14. Case study 3
Refiner has seen significant
dollar benefits
Improved operations and
small capex opportunities
Monitoring automation
giving time back to
engineers
Greater engagement with
simulation and optimization
Large US & European
refiner uses continual
model validation through
performance monitoring to
give unit engineers
confidence in model and to
make always up-to-date
models available on
demand

17. Excellence
is never an accident. It is always the result
of high intention, sincere effort, and
intelligent execution; it represents the wise
choice of many alternatives - choice, not
chance, determines your destiny.
