  • Method of reducing moisture and solid content of bitumen extracted from tar sand minerals
    Patent number: 6019888
    Abstract: Tar sand is upgraded to produce a hydrocarbon having a low concentration of water and solids by contacting a bitumen/diluent mix with an alkoxyalkylphenol alkoxylate surfactant prior to separation of a recoverable hydrocarbon phase. The separation of the bitumen/diluent mix into a recoverable hydrocarbon phase and a water/solid phase results in a recoverable hydrocarbon phase that meets the concentration of water and solids desired by tar sand processors. A further refinement of the method involves contacting the bitumen/diluent mix with an anionic and cationic flocculant following the surfactant for further improvement in separation.

  • Process for deabsorbing oil from oil absorbent
    Patent number: 5244566
    Abstract: A process is shown for deabsorbing oil from an oil absorbent material. A citric oil-in-water emulsion is formulated having an aqueous external phase and having a dispersed internal phase which is comprised of a distilled citric oil. The hydrocarbon contaminated material is immersed within the citric oil-in-water emulsion, whereby absorbed hydrocarbons are extracted from the oil absorbent material.
