How will your operation remain profitable?
Tough challenges ahead• Millions of tons of petcoke piling up
• Emissions rules shrinking coke segment
• Shortage of (expensive) natural gas
• Increased needs H2, steam, power
Excess coke, deficit hydrogen
• Plant & fuel level emissions mandates
• Reducing CO2 footprint of Oil Sands

Gasification … one way to break free
• Revalues petcoke to H2, power, steam
• Provides steam source for SAGD, extraction plant
• Become a power exporter vs importer
• Removes NG price volatility from H2 and fuel costs
Provides products you need, from petcoke you don’t

Gasification is a partial oxidation process that can convert any hydrocarbon into carbon monoxide
and hydrogen (syngas).
(HC)n + O2 H2 + CO
For example:
2 CH4 + O2 4 H2 + 2 CO[ Methane + oxygen hydrogen + carbon monoxide ]

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 volatile 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)
