  • Additives for improving hydrocarbon recovery
    Patent number: 9879512
    Abstract: Processes for recovering hydrocarbons from subterranean formations are disclosed. The hydrocarbon can be contacted with water or steam and one or more additives, and subsequently recovered. The hydrocarbon can be selected from the group consisting of heavy or light crude oil, bitumen, an oil sand ore, a tar sand ore and combinations thereof. The additive can be, for example, a fluorinated hydrocarbon, one or more alcohols, combinations of alcohols, and combinations of one or more alcohols and one or more fluorinated hydrocarbons. Compositions or mixtures including hydrocarbons, water or steam, and additives are also disclosed.
    Type: Grant

    Date of Patent: January 30, 2018
    Assignee: Ecolab USA Inc.
    Inventors: Kimberly Jantunen Cross, Anthony G. Sommese, Edward Maharaih
  • Processing aids to improve the bitumen recovery and froth quality in oil sands extraction processes
    Patent number: 8764974
    Abstract: Disclosed and claimed is a method for improving the froth quality and bitumen recovery in primary bitumen extraction processes by coagulant addition in the underwash feed water. Preferred coagulants are cationic or amphoteric polymers. Coagulant addition in the underwash feed water reduces the solids content reporting to the primary bitumen froth in a primary separation vessel (PSC). This treatment program can also be combined with dispersant addition in the dilution make-up feed water into a PSC. Preferred dispersants are low molecular weight anionic polymers.
