Oil for Export: Tar Sands Bitumen Cannot be Refined in Eastern Canada

Refineries usually require a coker unitto remove the carbon from bitumen. To remove the carbon, bitumen is heated in large steel coke drums at higher temperatures (480 degree Celsius) and for longer periods of time than typical conventional oil refinery is capable of. Hydrogen is added afterwards to make bitumen more like a liquid-fuel.

Coal gasification Coal gasification is the process of producing syngas —a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2 ), carbon dioxide (CO 2 ), methane (CH 4 ), and water vapour (H 2 O)—from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas".
