Abstract: Methods are provided for extracting heterocyclic compounds, organometallic compounds, and polynuclear aromatic hydrocarbons from a hydrocarbon feedstock such as crude oil or a crude fraction. The heterocyclic compounds and organometallic compounds are removed from the hydrocarbon feedstock through one or more successive extractions to form a first raffinate. The extractions use a first solvent system containing an ionic liquid formed from carbon dioxide and water. The polynuclear aromatic hydrocarbons are removed from the first raffinate using a second solvent system containing an aprotic solvent such as NMP, DMSO, aromatics, or combinations thereof. The extracted compounds remain chemically intact and may be fractionated for further applications. Further methods are provided for producing a hydrocarbon raffinate having reduced levels of heterocyclic compounds, organometallic compounds, and 2-4 cycle polynuclear aromatic hydrocarbons.

Abstract: Methods of extracting 1-4 cycle heterocyclic compounds and 2-5 cycle polynuclear aromatic hydrocarbons from a hydrocarbon feedstock are described. The methods include providing a hydrocarbon feedstock containing crude oil fractions, and determining an A/R ratio and an asphaltene concentration of the hydrocarbon feedstock. Based upon the A/R ratio and the asphaltene concentration, the treatable hydrocarbon feedstock undergoes one or more of cracking and fractionating. Subsequently, at least one targeted portion of the heterocyclic compounds is extracted from the fractionated stream with an aqueous solvent. A stream containing the 2-5 cycle polynuclear aromatic hydrocarbons is transferred to an extractor and the 2-5 cycle polynuclear aromatic hydrocarbons are extracted with a solvent system comprising an aprotic solvent.

Abstract: 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.

Abstract: A process and system for improving the efficiency of regenerating a CO 2 -rich liquid absorbent stream following contact in an absorption zone with, e.g., a flue gas stream from which it has absorbed CO 2 , and recovering a substantially pure stream of includes passing the pressurized liquid sorbent through a heating zone to heat it to the desorption temperature, e.g., to about 80°-85°C for aqueous K 2 CO 3 sorbent, introducing the heated liquid sorbent into a cyclone separation zone where the combination of increased temperature, reduced pressure and the centrifugal forces on the liquid/gas mixture result in a relatively more rapid and efficient separation of the CO 2 from the liquid sorbent from which it has been released. The CO 2 -lean liquid sorbent descends to the bottom of the cyclone separator and is recovered, cooled and recycled to the absorption zone; the CO 2 withdrawn from the cyclone separation zone passes through a condenser to remove moisture and any other condensates present, and the CO 2 is recovered for storage or use in downstream processes.

Abstract: A demulsification process for extracting surface active biochemical products from crude oil and its fractions when they are used as feedstock during biochemical productions utilizes subcritical/supercritical C0 2 as a proton pump. The process also includes a pH tuning step, thereby inducing demulsification and precipitation of biochemical products into the aqueous phase, but avoiding asphaltene precipitation by apriori addition of resinous solvents derived from crude oil or bioresources. The biochemical products are then extracted from the aqueous phase via temperature change or some other technique.
