ABSTRACT:
Acidic solvent compositions and method for separating bituminous products from tar sands which do not require a high shear environment employing such acidic solvent compositions are disclosed. The acidic solvent compositions comprise from about 15 to about 30 volume percent of an aqueous amine modified acidic constituent having a pH value of less than about 1, from about 1 to about 20 volume percent hydrofluoric acid, from about 5 to about 20 volume percent of a friction reducing compound, and from about 40 to about 80 volume percent of a hydrocarbon solvent. The aqueous amine modified acidic constituent of the acidic solvent compositions is prepared by (a) mixing from about 45 to about 80 weight percent hydrochloric acid with from about 20 to about 55 weight percent phosphoric acid to produce a substantially homogeneous acidic mixture; (b) mixing the acidic mixture with an effective amount of water to provide an aqueous acidic mixture; (c) admixing from about 2 to about 20 weight percent of a hydroxy carboxylic acid and from about 0 to about 20 weight percent of a dicarboxylic acid into the aqueous acidic mixture to produce a hydroxy carboxylic acid containing aqueous acidic mixture; and (d) admixing a minor effective amount of a polyamine with the hydroxy carboxylic acid containing aqueous acidic mixture.
