    摘要: Methods for recovering organic heteroatom compounds from a hydrocarbon feedstock include feeding into a contactor a hydrocarbon feedstock and an aqueous solvent to form an extraction mixture of the aqueous solvent with the hydrocarbon feedstock. The hydrocarbon feedstock includes a hydrocarbon and an organic heteroatom compound. The aqueous solvent includes an ionic liquid formed from pressurized carbon dioxide and water. A pressure and temperature of the extraction mixture may be established that together tune the aqueous solvent to selectively form a solvent complex with the at least one organic heteroatom compound. Then, the solvent complex is extracted to a recovery vessel from the extraction mixture in the contactor. By adjustment of a recovery temperature of the recovery vessel, a recovery pressure of the recovery vessel, or both, the solvent complex decomposes into carbon dioxide and the organic heteroatom compound. The organic heteroatom compound is then recovered from the recovery vessel.

    摘要: Methods for demulsifying an emulsified petroleum source having a predetermined resin-to-asphaltene ratio without substantial aggregation or precipitation of asphaltenes may include adding a resin supplement to the emulsified petroleum source to form a resin-supplemented emulsion having a resin-to-asphaltene ratio above a predetermined critical value. An acidic-to-basic ratio of acidic functional groups to basic functional groups in the supplemented emulsion may be adjusted to be from about 0.25 to about 4.0. The resin-supplemented emulsion may be contacted with carbon dioxide to form an initial mixture having an emulsified oil phase and an emulsified aqueous phase. The initial mixture may be stabilized to facilitate rupture of the resin-supplemented emulsion, to cause phase separation, and to allow removal of a separated oil phase. The resin-to-asphaltene ratio being above the predetermined critical value in the supplemented emulsion maintains asphaltene suspension during demulsification, such that asphaltene agglomeration and precipitation are avoided.
