ABSTRACT:
Heavy crude oil is recovered and processed at a refinery through (a) a distillation zone(s), (b) a solvent deasphalting unit (c ) a high pressure air partial oxidation gasifier to produce a CO-rich gas mixture including hydrogen, (d) a shift reactor and (e) a purification step to produce 99.9% pure hydrogen. The hydrogen is used to treat a deasphalted oil fraction and distillate hydrocarbon fractions obtained from the crude oil. The process is considered integrated in the sense that the purified hydrogen recovered from the heavy crude oil is used to treat hydrocarbons recovered from the same crude oil.
