    摘要: The present disclosure 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 disclosure involves the step of treating oil sands with a propylene oxide capped glycol ether described by the structure: RO—(CH2CH2O)m(CH2CH(CH3)O)nH wherein R is a linear, branched, cyclic alkyl, phenyl, or alkyl phenyl group of at least 4 carbons, and m and n are independently 1 to 3.

    摘要: 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 ethylene oxide capped glycol ether described by the structure: RO—(CH2CH(CH3)O)m(C2H4O)n, H wherein R is a linear, branched, cyclic alkyl, phenyl, or alkyl phenyl group of greater than 5 carbons and m and n are independently 1 to 3.
