How will your refinery remain profitable?
Source: Mitretek, GTC 20001For a typical 150MBPD refinery to meet Tier II specs
Tough challenges ahead for refiners• Crude getting heavier/sour (more petcoke)
• Emissions rules shrinking coke segment
• Shrinking Fuel Oil demand
• Need to create value from bottom products
Excess coke, deficit hydrogen
• Plant & fuel level emissions mandates
• Increased hydrogen demand +38MMscfd1
• Increasing costs of power and gas

Gasification … one way to break free
• Removes NG price volatility from H2 and fuel costs
• Revalues existing/planned bottoms to power, H2, syngas, CTL
• Increased flexibility in crude selection (opportunity crudes, differentials)
• Become a power exporter vs importer

Global petcoke production Mt/yr
A growing problem
Source: Mitretek, GTC 20001Jacobs Consultancy – Alberta Petcoke ForecastERCB – Alberta’s Energy Reserves 2007
•Global petcoke production to increase 50% by 2020
•Alberta held inventories of more than 50MM tons in 2007
•More than 220MM MT in Alberta long-term storage by 2020
Increasing glut of inventory
But … “It has the potential of becoming a future energy resource through a process called gasification and could possibly reduce the demand for natural gas.” - Energy Resources Conservation Board

Historically low price vs natural gas
• Has a very high BTU content• Low ash content – no need to “melt rocks”• No transportation costs “Refinery Mine-Mouth”• Eliminate coke logistics needs (shipping, marketing, liability)

Synergies with existing refinery
• Coke handling facility for feed and slag disposal• Reuse SMR & steam boilers for backup• Disposal of RCRA wastes, off spec oils, heavy cycle oil, resid, etc.
