  • Process for upgrading heavy oil and bitumen
    Patent number: 9469816
    Abstract: Disclosed is a process for the upgrading and demetallizing of heavy oils and bitumens. A crude heavy oil and/or bitumen feed is supplied to a solvent extraction process 104 wherein DAO and asphaltenes are separated. The DAO is supplied to an FCC unit 106 having a low conversion activity catalyst for the removal of metals contained therein. The demetallized distillate fraction is supplied to a hydrotreater 110 for upgrading and collected as a synthetic crude product stream. The asphaltene fraction can be supplied to a gasifier 108 for the recovery of power, steam and hydrogen, which can be supplied to the hydrotreater 110 or otherwise within the process or exported. An optional coker unit 234 can be used to convert excess asphaltenes and/or decant oil to naphtha, distillate and gas oil, which can be supplied to the hydrotreater 220.

  • Bitumen production-upgrade with common or different solvents
    Patent number: 7749378
    Abstract: Disclosed is a process for the upgrading of heavy oils and bitumens, where the total feed to the process can include heavy oil or bitumen, water, and diluent. The process can include the steps of solvent deasphalting 110 the total feed 105 to recover an asphaltene fraction 116, a deasphalted oil fraction 118 essentially free of asphaltenes, a water fraction 112, and a solvent fraction 114. The process allows removal of salts from the heavy oils and bitumens either into the aqueous products or with the asphaltene product.
