Abstract
A water-based separating composition for separating hydrocarbons from hydrocarbon-containing material includes at least about 71% by weight water, a hydrotropic agent, a dispersant having flocculating characteristics, a wetting agent, and at least one acid and at least one base in amounts sufficient to provide the separating composition with a pH of about 7 to about 8.5. The hydrotropic agent and the dispersant having flocculating characteristics are different.
Claims42
A water-based separating composition for separating hydrocarbons from hydrocarbon-containing material, said separating composition comprising:
- at least about 71% by weight water;
- a hydrotropic agent;
- a dispersant having flocculating characteristics;
- a wetting agent;
- and
- at least one acid and at least one base, in amounts sufficient to provide the separating composition with a pH of about 7 to about 8.5;
- wherein the hydrotropic agent and the dispersant having flocculating characteristics are different.
A water-based separating composition for separating hydrocarbons from hydrocarbon-containing material, said separating composition comprising:
- at least about 71% by weight water;
- from about 0.1% to about 4% by weight of a hydrotropic agent;
- and
- from about 0.25% to about 4.5% by weight of a dispersant having flocculating characteristics;
- from about 0.001% to about 2.5% by weight of a wetting agent;
- and
- at least one acid and at least one base in amounts sufficient to provide the separating composition with a pH of about 7 to about 8.5,
- wherein the hydrotropic agent and the dispersant having flocculating characteristics are different.
A water-based separating composition for separating hydrocarbons from hydrocarbon-containing material, said separating composition comprising:
- at least about 71% by weight water;
- from about 0.1% to about 4% by weight of a hydrotropic agent;
- and
- from about 0.25% to about 4.5% by weight of a dispersant having flocculating characteristics;
- from about 0.001% to about 2.5% by weight of a wetting agent;
- from about 1.7% to about 8.6% by weight of at least one acid;
- and
- from about 2% to about 9.5% by weight of at least one base;
- wherein the separating composition is utilized at a pH of about 7 to about 8.5, the separating composition is essentially free of organic solvent and the hydrotropic agent and the dispersant having flocculating characteristics are different.
