Alberta Ingenuity, Imperial Oil & CMASTE The Oil Sands Process 1.the overburden is stripped from the mineable oil sand (<75 m) 2.the oil sand is mined with large shovels and trucks 3.the oil sand is crushed and mixed with hot water and a base (to increase pH) before being hydrotransported in a pipe to the extraction plant (This starts the extraction of bitumen.) 4.the oil sand and water mixture is transferred to a large separatory funnel/tank—bitumen froth, water, and sand are separated 5.air is added to help float the bitumen froth to the top of the mixture and to be skimmed off by a large rotating paddle 6.the bitumen is upgraded to synthetic crude oil by cracking-- large aromatic molecules into smaller aromatic and aliphatic ones 7.the sulfur, nitrogen and oxygen atoms and double bonds are eliminated from the sour synthetic crude by hydrotreating separate fractions of the cracked bitumen with hydrogen 8.the synthetic crude is shipped to a refinery to be refined into gasoline and other petroleum fractions
