  • METHOD TO EXTRACT BITUMEN FROM OIL SANDS USING AROMATIC AMINES
    Publication number: 20190225889
    Abstract: The present invention relates to an improved bitumen recovery process from oil sands. The oil sands may be surface mined and transported to a treatment area or may be treated directly by means of an in situ process of oil sand deposits that are located too deep for strip mining. Specifically, the present invention involves the step of treating oil sands with an aromatic amine.

  • Method of extracting bitumen from oil sands with a propylene oxide capped glycol
    Patent number: 10138719
    Abstract: Oil sands may be surface mined and transported to a treatment area or may be treated directly by means of an in situ process of oil sand deposits that are located too deep for strip mining. A bitumen recovery process may be used to extract bitumen from oil sands. Specifically, the bitumen recover process involves a step of treating oil sands with a propylene oxide capped glycol ether described by the structure: RO—(C2H4O)n—CH2CH(CH3)OH wherein R is a linear, branched, or cyclic alkyl, phenyl, alkyl phenyl group and n is 1 to 10.

  • Method to extract bitumen from oil sands
    Patent number: 9790431
    Abstract: The present invention relates to an improved bitumen recovery process from oil sands. The oil sands may be surface mined and transported to a treatment area or may be treated directly by means of an in situ process of oil sand deposits that are located too deep for strip mining. Specifically, the present invention involves the step of treating oil sands with a glycol ether amine described by the following structure: R—(OC2H4)x—NH2 or R—(OCH2CH(CH3))y— NH2 wherein R is a C1 to C6 alkyl group or a phenyl group and x and y independently are 1 to 3.
