(EN) ENHANCED STEAM EXTRACTION OF BITUMEN FROM OIL SANDS
(FR) EXTRACTION À LA VAPEUR D'EAU AMÉLIORÉE DU BITUME CONTENU DANS DES SABLES BITUMINEUX
Abstract
(EN)
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 of at least 4 carbons, and m and n are independently 1 to 3.
(FR)
L'invention concerne un procédé amélioré de récupération du bitume contenu dans des sables bitumineux. Les sables bitumineux peuvent être exploités à ciel ouvert et transportés vers une zone de traitement ou peuvent être traités directement au moyen d'un procédé in situ de dépôts de sables bitumineux qui sont situés trop profondément pour une exploitation en découverte. La présente invention comprend en particulier l'étape de traitement de sables bitumineux avec un éther de glycol coiffé d'oxyde de propylène décrit par la structure : RO-(CH2CH2O)m(CH2CH(CH3)O)nH, dans laquelle R représente un groupe alkyle linéaire, ramifié, cyclique, un groupe phényle ou un groupe alkylphényle constitué d'au moins 4 carbones, et m et n valent indépendamment de 1 à 3.
