  • Publication number: 20140251875
    Abstract: A process and system to separate crude from tar sands. A tar sand and crude oil mixture is created using ground tar sands. The tar sand and crude oil mixture is mixed under high pressure in a treatment vessel with either natural gas or exhaust gas from an internal combustion engine. The mixture is then moved through a entrainment vessel still under the high pressure. When the mixture is removed from the entrainment vessel excess gas is removed from the mixture. The crude oil is then separated from the sand typically through a cyclone separator. A portion of the crude oil may be used to mix with the ground tar sand on the front end of the process.

  • Patent number: 4863586
    Abstract: In a first condensation stage (which is on the rising current end of the low-temperature carbonization drum and the equipment for which is integrated) quenching is done with a cooled low-temperature carbonization oil fraction containing solids. Simultaneously the whole discharge opening placed on the rising current end in the base region of the low-temperature carbonization drum for the volatile components of the low-temperature carbonization process is continuously scrubbed clean with the low-temperature carbonization oil fraction containing solids. Additionally, the volatile and liquid components are also drawn off simultaneously.

  • Patent number: 4758331
    Abstract: Fine particles of solid fossil fuels are pyrolyzed by passage in a thin layer through a heating zone at successively higher temperatures in a non-oxidizing atmosphere while rapidly separating and removing volatile pyrolysis products. The resulting char may be first treated with mineral acid or employed directly in the hydroprocessing of additional solid fossil fuel to liquid fuels. Alternatively, the acid-washed char may be hydrotreated to afford an improved char product having a low sulfur and mineral content.

  • Patent number: 4692238
    Abstract: A process for recovery of organic oils and residues in association with inorganic solids by solvent extraction and for the recovery of solvent used for the extraction. The organic solvent extracted inorganic solids having remaining associated organic solvent is fluidized in a bed with fluidizing gas comprising superheated vapor of the organic solvent vaporizing and removing a substantial portion of the associated organic solvent. Then the solids are countercurrently contacted with a combustion gas stream at a lower temperature than the solids physically stripping a substantial portion of the residual solvent from the solids, the combustion gas stream being enhanced for combustion by comprising stripped organic solvent and by being heated.

  • Patent number: 4636300
    Abstract: Process for sump-phase hydrogenation with integrated gas-phase hydrogenation relevant parameters being adjusted so that an economical heat recovery for the entire system is achieved, despite increasing incrustation of the mash heat exchanger and the increasing deactivation of the gas-phase catalyst. The process-relevant temperatures of the intermediate precipitator and of the gas-phase reactor are precisely adjusted by the use of head coolers which follow the sump-phase hydrogenator, and by head coolers which precede the intermediate precipitator. The procedure is such that the waste heat from the sump-phase products is partially recovered by using it to heat the raw materials constituting the gas phase and by feeding it back again to the mash heater.

  • Patent number: 4592826
    Abstract: A process for improving the upgrading/conversion of hydrocarbonaceous materials such as coals, petroleum residual oils, shale oils and tar sand bitumens. In the process, the free radicals formed from thermal cracking of the hydrocarbons are reacted with the free radicals formed by the thermal cracking of a free radical forming chemical reactant, such as dimethyl ether, to yield stable low molecular weight hydrocarbon distillate products. The hydrocarbonaceous feed material is preheated to a temperature of 600.degree.-700.degree. F. and the hydrocarbon and the free radicals forming chemical, such as dimethyl ether, are passed through a flow reactor at temperature of 750.degree.-900.degree. F., pressure of 200-1000 psi, and liquid hourly space velocity of 0.3 to 5.0 LHSV. Free radicals formed from the hydrocarbon feed material and from the ether material react together in the reactor to produce low molecular weight hydrocarbon liquid materials.
