Removal of contaminants from organic compositions
Patent
·
OSTI ID:6369632
Metals, nitrogen and/or sulfur, particularly vanadium, nickel and nitrogen, are removed from organic compositions, particularly heavy hydrocarbon oils, by contacting the organic compositions with a halogenating agent, preferably phosphorus oxychloride, under conditions sufficient to form a distinct phase including the contaminants, which is separable from the organic composition and separating the distinct phase from the organic composition as by filtration, decantation, and the like. In another embodiment of the present invention, the treatment with the halogenating agent is carried out in conjunction with treatment with an acid gas and water, as a combination of carbon dioxide and water, or a solvent.
