摘要： Provided herein are liquid polymer (LP) compositions comprising an acrylamide (co)polymer, as well as methods for preparing inverted polymer solutions by inverting these LP compositions in an aqueous fluid. The resulting inverted polymer solutions can have a concentration of acrylamide (co)polymer of from about 50 to about 15,000 ppm, and a filter ratio of 1.5 or less at 15 psi using a 1.2 μm filter. Also provided are methods of using these inverted polymer solutions in dewatering, clarification, flocculation and/or thickening applications, and the like.

摘要： An inverse emulsion composition comprising: one or more hydrophobic liquids having a boiling point at least about 100° C.; up to about 38% by weight of one or more acrylamide-(co)polymers; one or more emulsifier surfactants; and one or more inverting surfactants; wherein, when the composition is inverted in an aqueous solution, it provides an inverted solution having a filter ratio using a 1.2 micron filter (FR1.2) of about 1.5 or less.

摘要： The invention relates to a surfactant composition comprising an ionic liquid prepared from an unsubsituted or substituted primary, secondary or tertiary amine, or from an unsubstituted or substituted pyridine, amidine or guanidine with at least one fatty acid and/or resin acid. The invention also relates to a method for treating bitumen froth from a separation process, where bitumen is separated from mineral solids. The method comprises addition of said surfactant composition to the diluent and/or to the froth before phase separation.
