  • Process for the treatment of produced water from chemical enhanced oil recovery
    Patent number: 10968121
    Abstract: The present invention relates to a process for the treatment of water from the production well of chemical enhanced oil recovery (CEOR) extraction. In particular, the process relates to the treatment of produced water with a combination of reagents to clarify the water, the reagents being selected from (i) a dithiocarbamate polymer which is water-soluble and has a molecular weight of 00 or more and (ii) a metal ion selected from the group comprising a cation of a transition metal, aluminium and lead, and an apparatus therefor. The use of such reagents in the clarification of produced water from polymer flood from chemical enhanced oil recovery is also disclosed.
    Type: Grant

  • Process and system for dewatering oil sands fine tailings
    Patent number: 9963365
    Abstract: A dewatering process comprises dispersing an anionic polymer flocculant in a slurry comprising water and oil sands fine tailings to form flocs comprising fines bridged by the anionic polymer flocculant. A cationic polymer flocculant is subsequently dispersed in the flocculated slurry to further flocculate the flocs and form floc aggregates. The floc aggregates comprise flocs bridged by the cationic polymer flocculant. The floc aggregates are then compressed to remove water and form a dewatered compact. A system is also provided for the dewatering processes using inline mixtures and a filter press.
