| 101 | Production of high flash point topped crude and high flash point asphalt | US3567628D | 1968-10-25 | US3567628A | 1971-03-02 | POOL JOE VAN |
| A HIGH FLASH POINT REDUCED CRUDE OIL AND A HIGH FLASH POINT SPECIFICATION ASPHALT ARE PRODUCED BY FIRST DISTILLING A CRUDE OIL IN A DISTILLATION OPERATION PRACTICED IN A DISTILLATION ZONE HAVING A FRACTIONATION SECTION AND A STRIPPING SECTION IN WHICH A LOWER PORTION OF THE FRACTIONATION SECTION IS MAINTAINED AT THE HIGHEST TEMPERATURE IN THE OVERALL OPERATION AND TO WHICH IS PASSED CRUDE OIL HEATED TO SUBSTANTIALLY SAID HIGHEST TEMPERATURE. A PORTION OF DISTILLATE TAKEN FROM SAID LOWER PORTION OF SAID FRACTIONATION SECTION IS ADMIXED WITH THE CRUDE OIL AND HEATED TOGETHER THEREWITH AND THEREFORE, REINTRODUCED INTO THE OPERATION. THE HEATED CRUDE OIL IS, IN ANY EVENT, INTRODUCED INTERMEDIATE THE FRACTIONATION SECTION AND THE STRIPPING SECTION. ALTERNATELY, DISTILLATE IN THE LOWER PORTION OF THE FRACTIONATION SECTION CAN BE HEATED THEREIN TO THE DESIRED HIGHEST TEMPERATURE OR SUBSTANTIALLY HIGHEST TEMPERATURE IN, THE OVERALL OPERATION. THERE IS AVOIDED THE PASSING OF DISTILLATE PRODUCED IN OR REINTRODUCED INTO THE OPERATION TO THE STRIPPING SECTION BY REMOVING GAS OIL FROM A POINT ABOVE SAID LOWER PORTION OF SAID FRACTIONATION SECTION RESPONSIVE TO LIQUID LEVEL IN SAID LOWER PORTION OF SAID FRAC-
TIONATION SECTION. A TRAP-OUT TRAY FROM WHICH THE DISTILLTE IS REMOVED AND PASSED TO THE FURNACE IS OPERATED SO AS TO PREVENT OVERFLOW OF DISTILLATE THEREFROM INTO THE STRIPPING SECTION. A LEVEL CONTROLER ON THE TRAP-OUT TRAY REGULATES THE RATE OF REMOVAL OF GAS OIL FROM THE FRACTIONATION SECTION SO AS TO INSURE PRODUCTION OF DESIRED REFLUX IN THE LOWER PORTION OF THE FRACTIONATION SECTION. A HIGH FLASH POINT REDUCED CRUDE IS WITHDRAWN FROM THE LOWER PORTION OR BOTTOM OF THE STRIPPING SECTION. FRACTIONS BOILING LOWER THAN THE GAS OIL ARE TAKEN OFF FROM THE UPPER PORTIONS OF THE FRACTIONATION SECTION. THE REDUCED CRUDE OIL IS SOLVENT EXTRACTED AS BY A PROPANE EXTRACTION OPERATION TO PRODUCE SPECIFICATION HIGH FLASH POINT ASPHALT. |

| Systems and methods are provided for block operation during lubricant and/or fuels production from deasphalted oil. During “block” operation, a deasphalted oil and/or the hydroprocessed effluent from an initial processing stage can be split into a plurality of fractions. The fractions can correspond, for example, to feed fractions suitable for forming a light neutral fraction, a heavy neutral fraction, and a bright stock fraction, or the plurality of fractions can correspond to any other convenient split into separate fractions. The plurality of separate fractions can then be processed separately in the process train (or in the sweet portion of the process train) for forming fuels and/or lubricant base stocks. This can allow for formation of unexpected base stock compositions. | ||||||
| 105 | Process for producing mesophase pitch by hydrogenation of high-temperature coal tar | US14372006 | 2012-04-06 | US09994775B2 | 2018-06-12 | Hongmei Zhao; Jieshan Qiu; Kam Shing Philip Siu; Baoming Li; Junde Steve Lu; Nan Xiao |
| A process for producing mesophase pitch from high-temperature coal tar comprises: removing salts and quinoline insoluble fraction from a high-temperature coal tar to obtain a decant oil; using the decant oil as a hydrogenation feedstock, or pre-distilling the decant oil to obtain a residue with a boiling point higher than 230 and formulating the residue into a hydrogenation feedstock; catalytic hydrorefining the hydrogenation feedstock to obtain a hydrofined oil; distilling the hydrofined oil to obtain hydrogenated pitch; and subjecting the hydrogenated pitch to the thermal polymerization to obtain the mesophase pitch. The process has features such as an easily controllable degree of hydrogenation, complete removal of impurities, good raw material flowability, not tending to form the carbon deposition and the coking during the process, and not tending to jam the reactor. The product has a high content of mesophase pitch, a low softening point and a low impurity content. | ||||||

| The process for treating a hydrocarbon-based heavy residue (1), in particular bituminous residues with a high asphaltene content, comprises the following operations: A) bringing the heavy residue to be treated to a temperature within the range of 325-500° C.; B) subjecting the heavy residue to be treated to a substantially adiabatic expansion in an environment at a pressure equal to or lower than about 0.1 bara, and at a temperature equal to or lower than 450° C., so as to separate, from the heavy residue to be treated, a first less volatile fraction (17) having a boiling point at atmospheric pressure equal to or higher than 540° C. and whose solid and/or anhydrous residue prevalently contains asphaltenes insoluble in pentane and/or other residues insoluble in tetrahydrofuran. It allows a more effective flushing, and also to actuate the process in an extremely simple plant and without centrifugations. | ||||||
