Specific TARO Analysis Conclusions examples • Overcapacity allows reduction in redundancy/availability • Additional steam source improves key product efficiency by 0.4% • Available storage tanks could be taken out of service without reducing unit on stream factor • Analysis shows unit loading will be significantly lower than design capacity • Removal of the spare feed charge pump will not reduce the on stream factor • Potential for 0.6% efficiency improvement if cross-over line is installed between two units increasing operational flexibility during outages 2003 Clean Fuels Challenge
General Findings of Clean Fuel Projects TARO analysis • Projects focus on unit availability only – Missing opportunity to save CAPEX by balancing availability/overcapacity/storage. • Projects increase loading on key utility systems – Reduces available redundancy 2003 Clean Fuels Challenge
