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 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.
L'invention concerne un procédé amélioré de récupération de bitume à partir de sables bitumineux. Les sables bitumineux peuvent être exploités à ciel ouvert et transportés vers une zone de traitement ou ils peuvent être traités directement par traitement in situ de dépôts de sable bitumineux situés trop profondément pour une exploitation en découverte. La présente invention comprend en particulier une étape de traitement de sables bitumineux avec un éther de glycol coiffé d'oxyde d'éthylène décrit par la structure : RO-(CH2CH(CH3)O)m(C2H4O)n H, R représentant un groupe alkyle, phényle ou alkyle-phényle linéaire, ramifié ou cyclique de plus de 5 atomes de carbone, et m et n représentant indépendamment de 1 à 3. |
