20120091041 | HYDROCARBON EXTRACTION OF OIL FROM OIL SAND - This invention provides a process for producing a crude oil composition from oil sand using a solvent comprised of a hydrocarbon mixture to extract or remove only a portion of the bitumen on the oil sand. The solvent type and the manner by which the extraction process is carried out has substantial impact on the quality of the extracted oil component. The solvent is designed so that it has the desired Hansen solubility parameters that enable the partial extraction of the desired oil composition. The solvent is further designed so that it can be comprised of multiple hydrocarbons having the appropriate boiling point ranges that enable the solvent to be easily recovered and recycle, without the need to externally provide for solvent make-up. | 04-19-2012 |

20130233772 | EXTRACTION OF OIL FROM OIL SAND - Disclosed is a process for extracting an oil composition from oil sand. The extraction process is carried out using a fluidizing medium to fluidize oil sand particles within a contact zone in which the fluidizing medium contacts the oil sand and maintains the oil sand in the fluidized state. At least a majority of the fluidizing medium is in a vapor or supercritical state within the contact zone. | 09-12-2013 |
20150014220 | PROCESS FOR PRODUCING A BITUMEN PRODUCT - Disclosed is a process for producing a high quality bitumen product derived from oil sand. The process for producing the high quality bitumen product involves a dual phase bitumen extraction process. In this dual phase process, a very high quality deasphalted crude oil is extracted from the oil sand in a solvent treatment first phase. The second phase of the process produces a high quality bitumen product from the solvent-treated oil sand. | 01-15-2015 |
20150090634 | PROCESS FOR PRODUCING TRANSPORTATION FUELS FROM OIL SANDS-DERIVED CRUDE - Disclosed are processes for producing a transportation fuel from a high quality oil sands-derived crude oil. The oil sands-derived crude oil is provided as a feed source for a catalytic conversion reaction, which produces the product useful as the transportation fuel. The oil sands-derived crude oil has an ASTM D7169 5% distillation point of from 400° F. to 700° F. Transportation fuel is produced from the provided oil sands-derived crude oil by treating the oil sands-derived crude oil through at least one catalytic cracking process and mild hydrotreating process. | 04-02-2015 |
20150090641 | PROCESS FOR PRODUCING TRANSPORTATION FUELS FROM OIL SANDS-DERIVED CRUDE - Disclosed are processes for extracting deasphalted crude oil from oil sand. Deasphalted crude oil can be extracted using a hydrocarbon recycle solvent stream having specified Hansen blend parameters, with the oil sand being contacted with the hydrocarbon recycle solvent stream in a contact zone of a vessel to separate not greater than 80 wt % of the bitumen present on the oil sand. The separated bitumen is considered a deasphalted crude oil stream, since it has an asphaltenes content substantially lower than that of the total bitumen initially present on the oil sand. The deasphalted crude oil stream can be treated using a hydrotreating catalyst or catalytic cracking catalyst to produce transportation fuel. | 04-02-2015 |
20150175892 | PROCESS FOR PRODUCING CRUDE OIL AND BITUMEN PRODUCTS - Disclosed are processes for producing crude oil and bitumen products of relatively high quality from oil sand. The processes for producing the high quality crude oil and bitumen products involve a Phase I and/or Phase II extraction solvent. According to the Phase I process, a high quality bitumen-derived crude oil can be produced using a Phase I type solvent. According to the Phase II process, a substantial amount of the bitumen on the oil sand can be extracted using a Phase II type solvent, while producing a relatively dry tailings by-product. The Phase I and Phase II extraction processes can be carried out independently or in conjunction with one another. | 06-25-2015 |
20150175893 | HYDROPROCESSING OIL SANDS-DERIVED, BITUMEN COMPOSITIONS - Disclosed are processes for producing deasphalted bitumen and heavy bitumen compositions from oil sands and processes for upgrading the bitumen compositions. The processes for producing the deasphalted bitumen and heavy bitumen compositions involve a Phase I and/or Phase II extraction solvent. According to the Phase I process, a high quality oil sands-derived, deasphalted bitumen can be produced using a Phase I type solvent. According to the Phase II process, a substantial amount of the heavy bitumen on the oil sand can be extracted using a Phase II type solvent, while producing a relatively a tailings by-product that is non-harmful to the environment. The heavy bitumen from the Phase II type extraction process can be hydroprocessed for ready conversion into relatively high volumes of high quality transportation fuels. | 06-25-2015 |
20150175894 | PROPANE PROCESS FOR PRODUCING CRUDE OIL AND BITUMEN PRODUCTS - Disclosed are processes for producing bitumen-derived crude oil and heavy bitumen compositions from oil sand. The processes involve treating oil sand feedstock with a first hydrocarbon solvent comprised of propane to produce the bitumen-derived crude oil composition having an asphaltene content of not greater than 5 wt % pentane insoluble, and an oil-depleted oil sand. The oil-depleted oil sand is treated with a second hydrocarbon solvent comprised of propane and a fraction of the bitumen-derived crude oil composition to produce the heavy bitumen composition and oil sand tailings. The oil sand tailings are dried by contacting the tailings with a drying composition comprised of a majority of propane. | 06-25-2015 |
