Catlettsburg Refining
Complex and energy intensive processes
Continuous operation 24/7
Energy is second largest operating cost
Natural gas – 75%
Electricity – 25%
Managing energy is imperative to remaining competitive/viable
Resources and systems in place to monitor and improve
Daily operational
Medium-term activities
Long-term strategy and projects
Significant investments made and planned
4
Catlettsburg Refining
Expansive electrical infrastructure required
Refinery footprint is 600+ acres
There are 130 electric substations and approximately 2,000 electric motors
120-130 MW of demand to operate refinery
Largest Kentucky Power customer
>95% of consumption is for continuously running process equipment
Significant people resources monitor and maintain electricity infrastructure
13 engineers
25 electricians
60-80 electrical contractor personnel onsite daily
5
Improving Energy Efficiency
Part of our standard work practices
Short-term – daily operational monitoring
Medium-term – maintenance planning activities
Long-term – strategic projects
Effective energy management is an “all-above” approach
6
Monitoring Daily Operations
Significant benefits from daily attention to process operations
Tuning process heaters
Optimizing utilization of energy from process operations
Monitoring sources and uses of steam
Controlling the operation of large electrical users
7
Monitoring Daily Operations
Formal assessment program - Focus On Energy initiative – “FOE”
To accomplish – set standards for performance
Measure actual performance in real time
Communicate deviations from standards
8
Monitoring Daily Operations
Supported by technical, operations, and management personnel
Completed process unit reviews and identified 148 individual monitoring
points
Each point assigned a dollar value, tracked and reported
35% reduction with no investment
9
Medium-Term Activities
Equipment maintained to perform at optimum efficiency
Equipment upgrades and major maintenance efforts normally require a unit
shutdown
Cycle times between shutdowns can be 5-7 years
Data from routine equipment monitoring is used to develop shut down work
scope
10
Long-Term Strategy/Projects
On-going efforts to identify and implement energy reduction opportunities
Energy specific projects – Insulation upgrades, steam leak repairs and
upgrades, on-line analyzers, exchanger bundle upgrades
Energy assessment for other projects
Crude unit project example
Significant investment currently underway
Process and energy efficiency improvements incorporated into scope
Redesign of heat integration system to reduce consumption
Improvements to fired heater for improved efficiency
Fuel reduction of 720 MMBTU/day
Electricity reduction of 3,000 kwh/day
11
Long-Term Strategy/Projects
All projects reviewed for energy efficiency improvement opportunities
Standard practice to consider high efficiency motors
Participate in industry benchmarking studies
Identifies opportunities for improvement
Share and implement best practices across all MPC sites

Summary
Efficiently using all energy sources is a business imperative
Resources employed to manage and maintain energy infrastructure
Programs in place to monitor and improve performance
Efforts range from daily optimization to large multi-year, multi-million dollar
projects
