Abstract:
A method of reducing turbulent drag in a hydrocarbon liquid stream flowing though conduits, which comprises:(a) forming a solid hydrocarbon soluble polyolefin friction reducing agent from olefins containing from 2 to 30 carbon atoms;(b) finely dividing said soluble polyolefin friction reducing agent in the presence of a partitioning agent to provide a free flowing, polyalphaolefin material, said partitioning agent being a fatty acid wax;(c) dispersing the free-flowing polyalphaolefin particles in a substantially nonaqueous suspending fluid medium selected from the group consisting of alcohols containing 14 or less carbon atoms, glycols and glycol-ethers; and(d) adding said suspension to said hydrocarbon liquid stream in an amount of up to 100 ppm of said reducing agent to reduce friction during turbulent flow through said conduits.
