EXTRACTIVE SOLIDS REMOVAL FROM HEAVY FRACTIONS
Systems and methods are provided for separation of particles and/or asphaltenes from heavy hydrocarbon fractions. The heavy hydrocarbon fraction can correspond to a feed including particles or a processing effluent that includes particles. If the heavy hydrocarbon fraction is mixed with lower boiling fractions, a separation can be performed to reduce or minimize the amount of hydrocarbons that are present in the heavy hydrocarbon fraction. The heavy hydrocarbon fraction can then be mixed with a sufficient amount of a separation solvent to cause a phase separation. One phase can correspond to the separation solvent plus a portion of the hydrocarbons. The other phase can correspond to hydrocarbons rejected by the separation solvent plus the particles from the heavy hydrocarbon fraction. The phases can then be separated from each other using a solids-liquid centrifugal separator.
NON-AQUEOUS EXTRACTION OF BITUMEN FROM OIL SANDS
A non-aqueous process for producing bitumen from oil sands is provided, and includes contacting oil sands and solvent to produce solvent diluted bitumen and solvent diluted tailings. The solvent diluted bitumen is subjected to a first fines separation stage that produces an overflow solvent diluted bitumen stream with residual fines that is subjected to a second fines separation stage to remove residual fines and produce a solvent diluted bitumen stream, which is subjected to solvent recovery. The fines streams are subjected to washing to produce washed tailings and solvent wash liquor comprising solvent and bitumen. Another non-aqueous process for producing bitumen from oil sands is provided, and includes subjecting oil sands to solvent extraction, including displacing the oil sands material and a solbit counter-currently and horizontally, and recovering a bitumen enriched solbit stream which is subjected to fines separation and subjecting the solvent diluted bitumen stream to solvent recovery.
SIMULTANEOUS PRODUCTION OF HIGH VALUE DE-AROMATIZED KEROSENE AND BTX FROM REFINERY HYDROCARBONS
The present disclosure discloses a process for obtaining an aromatic lean stream and an aromatic rich stream from a hydrocarbon feed, the process comprising: (a) obtaining a hydrocarbon feed; and (b) contacting the hydrocarbon feed with a solvent selected from a group consisting of alkyl aromatic hydrophilic polyethylene oxide, polyethylene glycols, and combinations thereof to obtain an aromatic lean stream and an aromatic rich stream. It further discloses a simultaneous process to obtain an aromatic lean stream and an aromatic rich stream. The present disclosure also discloses a process for obtaining de-aromatized kerosene from a hydrocarbon feed. Additionally, the present disclosure discloses a process for obtaining BTX from a hydrocarbon feed.
Non-aqueous extraction and separation of bitumen from oil sands ore using paraffinic solvent and deasphalted bitumen
A non-aqueous extraction (NAE) process for producing bitumen from oil sands ore can include a multistage bitumen extraction step where paraffinic solvent and deasphalted oil are added at a downstream stage of extraction at solvent-to-bitumen ratios below asphaltene precipitation onset threshold to remove bitumen from the solid mineral material, while the ore is added to a first stage to mix with the solvent-bitumen mixture and produce solvent diluted bitumen. The process includes recovering the solvent diluted bitumen and the solvent diluted tailings from the extraction step. The solvent diluted bitumen is subjected to deasphalting to produce solvent diluted deasphalted bitumen that is used as a source of the paraffinic solvent and deasphalted oil supplied to extraction. The tailings and asphaltene fraction from deasphalting can be subjected to washing and the washed material can then be subjected to sand solvent recovery. The NAE process can be operated within an operating envelop for effective and efficient performance.
