  • Patent number: 8852424
    Abstract: This invention is based upon the discovery that activated carbon can be used to sequester polycyclic aromatic hydrocarbons that may be present in asphalt and creosote compositions. The treatment of asphalt and creosote compositions with activated carbon accordingly reduces the level of free polycyclic aromatic hydrocarbons in such compositions by sequestering them therein or removing them from the composition. After being sequestered the polycyclic aromatic hydrocarbons remain trapped in the asphalt or creosote composition, and are not available to the environment during normal processing into useful industrial products. This sequestration reduces the risk of exposing humans and the environment to the polycyclic aromatic hydrocarbons which would otherwise be free to migrate from the asphalt or creosote product during manufacturing and the service life of the product.

The drag reducing polymer is introduced into a liquid hydrocarbon having an asphaltene content of at least 3 weight percent and/or an API gravity of less than about 26° to thereby produce a treated liquid hydrocarbon. The treated liquid hydrocarbon does not have a viscosity less than the viscosity of the liquid hydrocarbon prior to treatment with the drag reducing polymer. Additionally, the drag reducing polymer is added to the liquid hydrocarbon in the range from about 0.1 to about 500 ppmw.

    Abstract: A continuous process for fractioning, combination, and recombination of asphalt sources into asphalt components for pelletization of asphalt and asphalt-containing products such that the pellets formed are generally uniform in dimension, freely flowing, free from agglomeration, and the pelletized asphalt is packaged, and preferably compatibly packaged, for additional processing and applications.

  • Patent number: 8354067
    Abstract: Embodiments of a method and a system for recovering energy, materials or both from asphaltene-containing tailings are disclosed. The asphaltene-containing tailings can be generated, for example, from a process for recovering hydrocarbons from oil sand. Embodiments of the method can include a flotation separation and a hydrophobic agglomeration separation. Flotation can be used to separate the asphaltene-containing tailings into an asphaltene-rich froth and an asphaltene-depleted aqueous phase. The asphaltene-rich froth, or an asphaltene-rich slurry formed from the asphaltene-rich froth, then can be separated into a heavy mineral concentrate and a light tailings. Hydrophobic agglomeration can be used to recover an asphaltene concentrate from the light tailings. Another flotation separation can be included to remove sulfur-containing minerals from the heavy mineral concentrate. Oxygen-containing minerals also can be recovered from the heavy mineral concentrate.

  • Patent number: 8252168
    Abstract: A method for modifying asphalt comprises blowing an oxygen-containing gas through a base asphalt at a high gas flow rate while simultaneously agitating the base asphalt at a high shear rate and at an elevated temperature for a period of time that is effective to substantially improve at least two paving properties of the base asphalt. In preferred embodiments, modified asphalts are produced having both substantially improved rutting resistance and substantially improved fatigue resistance as compared to the base asphalt.

  • Patent number: 8231775
    Abstract: A process and apparatus is disclosed for converting heavy hydrocarbon feed into lighter hydrocarbon products. The heavy hydrocarbon feed is slurried with a particulate solid material to form a heavy hydrocarbon slurry and hydrocracked in a slurry hydrocracking unit to produce vacuum gas oil (VGO) and pitch. A first vacuum column separates VGO from pitch, and a second vacuum column further separates VGO from pitch. As much as 15 wt-% of VGO can be recovered by the second vacuum column and recycled to the slurry hydrocracking unit. A pitch composition is obtained which can be made into particles and transported without sticking together.

  • Patent number: 8221105
    Abstract: Systems for pelletizing hot asphaltenes are provided. Asphaltenic hydrocarbons can be dispersed to provide two or more asphaltenic particles. The asphaltenic hydrocarbons can be at a temperature of from about 175° C. to about 430° C. The asphaltenic particles can be contacted with a film of cooling medium. The film can have a thickness of from about 1 mm to about 500 mm. At least a portion of the asphaltenic particles can be solidified by transferring heat from the asphaltenic particles to the cooling medium to provide solid asphaltenic particles. The solid asphaltenic particles can be separated from at least a portion of the cooling medium.

  • Patent number: 8063004
    Abstract: A chemical composition of matter comprising a wax plasticizing agent (plasticizer) tributoxyethyl phosphate, a mixture of selected long chain fatty acids (preferably C10 to C22), and a mixture of selected low-surface tension surfactants, which when added in solution to crude oil or refined products has been shown to lower both the B.S. & W. (rag layer) and the coefficient of friction of crude oils and refined products. This chemical composition of matter is particularly useful as a wax liquefaction, dispersant, and solubilization agent for asphaltene and paraffins in crude oil and refined products. The reduction in the co-efficient of friction resulting from the addition of this product to crude oil will allow crude oil to pump through pipelines with a minimum amount of resistance due to friction (drag).
