Challenges for Our Industry > Increased Energy Prices > Reduced Margins > Stricter Governmental and Environmental
Legislation > Improve Corporate Image:
– Lean and Green
23 October 2012 PROPRIETARY INFORMATION 7
Rising Fuel Prices Make Investment in Saving Energy Highly Attractive
> Fuel prices have increased faster than plant capital costs – A 5 year payback in 1995
is now a 2 year payback – Incentive to invest in
capital projects & revisit older “uneconomic” projects
– Novel schemes could be attractive (heat pumps, divided wall columns, etc.)
> Also attractive to invest in engineering capabilities (manpower, tools, training)

KBC’s Proprietary “Best Technology” [BT] Energy Benchmarking Methodology
23 October 2012 14
BT Configuration Development
All economically justifiable ENCON built in (4 years payback on last piece of equipment):
- Furnaces 92% eff. - Optimised heat integration (pinch) and process features - Efficient Steam&Power system - All power generated at 80% eff. - Yield efficient
Collect Process data: - BT parameters - Energy Balances
Correlations Development
- BT process modelled - Parameters affecting energy performance varied - Sensitivity found - Correlations using important parameters developed
KBC’s Development Work
Application
Apply KBC Energy Costing
methodology - PEE for power - Steam costing
Calculate BT Target
for all units
Calculate Total energy consumption
for each process
Calculate BT index for
each process and whole
site
PROPRIETARY INFORMATION
BT Benchmarking and Gap Analysis > Best Technology (BT)
benchmarking compares actual energy usage to a BT energy usage
> 100% BT represents the best performance that could be expected from a modern plant designed with high efficiency components and features
> Performance gaps identified: – Steam and power – Heater performance – Heat Integration effectiveness – Process
