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

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
