    摘要： A system and method is described for separating solvent from a solvent-diluted bitumen feedstream from oil sands froth treatment processing. A distillation tower receives a first feedstream portion intermediate the tower at or above the solvent bubble point and a second feedstream portion at an upper end of the tower at temperature at about or lower than the dew point of bitumen. A bitumen liquid product is recovered from a tower bottom and a solvent product is recovered from an upper end as recycle solvent to the upstream froth treatment process. Prior to splitting into first and second portions, the feedstream may be flashed, the underflow forming the tower feedstream while the overhead vapor is available directly as recycle solvent. The two feedstream portions and temperatures thereof enable solvent recovery without the use of a reflux or a bottom reboiler.

    摘要： The invention discloses a rubber process oil and a process for manufacturing rubber process oils which are non-carcinogenic in nature. The process comprises of selectively producing Hildebrand solubility components enriched vacuum residue by selective distillation of reduced crude oil (RCO) to obtain minimum of 10 vol% boiling components in the range 490°C to 50°C, which leads to higher solubility of rubber process oil with an aniline point of less than 70°C and with extremely low concentration of selective polycyclic aromatics which makes the 15 product non-carcinogenic. The process comprises of selectively enriching higher Hildebrand solubility components in vacuum residue by vacuum distillation of reduced crude oil (RCO), then subjecting the enriched vacuum residue to solvent deasphalting process and subjecting the deasphalted oil to aromatic extraction process and then blending the enriched aromatic extract with Heavy Alkyl 20 Benzene(HAB) or Solvent processed base oil or hydroprocessed base oil or mixture thereof. The rubber process oils manufactured by the invented process have a polycyclic aromatics (PCA) content of less than 10 ppm, specifically benzo(a)pyrene content of less than 1ppm. They have aniline point less than 70°C but have high kinematic viscosity of 25 to 75 cSt at 100°C, pour point of 27°C or less and a flash point minimum of 250°C or more.

    摘要： The invention concerns with improved and more flexible deasphalting process for production of lube oil base stock as well as feed stock for secondary processes depending on requirement from heavy residual hydrocarbon oil containing saturates, aromatics, resins and asphaltenes etc by contacting the oil with a solvent comprising of hydrocarbon containing two to six carbon atoms, preferably LPG having C3-C4 hydrocarbons and mixture thereof at predetermined deasphalting conditions wherein the yield of deasphalted oil including its quality is controlled by varying the deasphalting conditions including the operating temperature. The yield variations of 15 to 60 wt% is achieved by swinging the temperature by about 10-20°C within the operative temperature range of 70-130°C keeping the rest of the operating conditions including solvent to feed ratio same. The LPG solvent can be recovered using supercritical mode of operation using technology known in the art and recycled.
