ABSTRACT:
A method of denitrogenating viscous oils containing a relatively high content of nitrogenous compounds and of disposing of a resulting high nitrogen content oil stream, characterized by forming a raw oil stream and a first viscous bottoms stream that would not be operably pumpable to a partial oxidation unit without the inclusion of viscosity lowering constituents; extracting the nitrogenous compounds from the raw oil stream with an operable acid solvent to produce a raffinate oil of low nitrogen content oil and an extract stream of low viscosity, high nitrogen content oil; recovering the acid solvent from the extract stream, simultaneously producing a small volume stream of low viscosity, high nitrogen content oil; admixing the low viscosity high nitrogen content oil with the high viscosity bottoms stream to provide a pumpable mixed stream; sending the mixed stream to a partial oxidation unit to produce hydrogen; employing the produced hydrogen for hydrogenation of the raffinate oil at mild conditions; and recycling the acid solvent to the extraction step. Additional and alternative steps are also disclosed.
