Abstract
A method and composition for reducing drag, reducing friction, reducing viscosity, and/or improving flow of viscous hydrocarbons including adding an effective amount of a drag-reducing composition containing a blend of turpentine liquids to a viscous hydrocarbon storage or pipeline operation and forming a drag-reducing mixture of viscous hydrocarbons and the blend of turpentine liquids.

A composition comprising a blend of turpentine liquids in an amount effective for reducing drag, reducing viscosity, and improving flow of a viscous hydrocarbon fluid through a pipeline, wherein said blend of turpentine liquids comprises 40-60% α-terpineol, about 0-10% α-pinene, about 5-20% β-pinene, and about 30-40% p-cymene by volume, wherein said blend of turpentine liquids further comprises a drag reducing polymer, and wherein the composition is not an emulsion and is substantially non-aqueous or non-aqueous.
A method of reducing drag, reducing friction, reducing viscosity, and/or improving flow of viscous hydrocarbons in a viscous hydrocarbons storage or pipeline operation, comprising adding an effective amount of a drag-reducing composition containing a blend of turpentine liquids to said viscous hydrocarbons storage or pipeline operation, and forming a drag-reducing mixture of viscous hydrocarbons and the blend of turpentine liquids, wherein said blend of turpentine liquids comprises 40-60% α-terpineol, about 0-10% α-pinene, about 5-20% β-pinene, and about 30-40% p-cymene by volume, further comprising injecting a drag reducing polymer, wherein an emulsion is not formed in any step of said method.

- about 40-60% α-terpineol, about 30-40% β-terpineol, about 5-20% β-pinene, and about 0-10% p-cymene by volume;
- about 50% α-terpineol, about 35% β-terpineol, about 10% β-pinene, and about 5% p-cymene by volume;
- about 50% α-terpineol, about 35% α-pinene, about 10% β-pinene, and about 5% p-cymene by volume;
- about 40-60% α-terpineol, about 30-40% α-pinene, about 5-20% β-pinene, and about 0-10% p-cymene;
- and 40-60% α-terpineol, about 0-10% α-pinene, about 5-20% β-pinene, and about 30-40% p-cymene by volume, further comprising injecting a drag reducing polymer, wherein an emulsion is not formed in any step of said method, wherein said adding step comprises adding 0.01% to 4% of the blend of turpentine liquids by weight of the viscous hydrocarbons.
