Abstract: A method for preparation of a reagent for reducing hydrodynamic drag of a turbulent flow of liquid hydrocarbons in pipelines, characterized by a high polymer content of at least 75 wt %, including mixing a 0.1-1.5 mm polymer reducing the hydrodynamic drag of a turbulent flow of liquid hydrocarbons with polymer non-solving solvents. The prepared product is a commodity form of the reagent with a high polymer content of at least 75 wt % used to reduce the hydrodynamic drag of the flow of liquid hydrocarbons in pipelines. The product prepared according to the described method is injected into the flow of hydrocarbon fluid transported through the pipeline using the injection apparatus that mechanically moves the product using a screw auger or screw feeder.

Abstract: The invention relates to inorganic and polymeric reagents and namely to pipeline transfer of petroleum and petroleum products. The method of production of a reagent for reduction of hydrodynamic resistance of liquid hydrocarbon flow in pipelines includes polymerization of C6-C14 alpha-olefins over catalyst and catalyst activator. Polymerization of C6-C14 alpha-olefins is conducted in the monomer medium with addition from 0.1 to 5 w/w of a saturated alicyclic hydrocarbon of C8-C32 composition and a saturated aliphatic hydrocarbon of C6-C18 composition subject to conversion of monomers from 96.0 to 99.5 w/w, using microspheric titanium trichloride as a catalyst, and a mixture of diethylaluminum chloride and triisobutylaluminum with weight ratio from 1:10 to 10:1 as a catalyst activator. Then a polymer with molecular weight more than 107 atomic mass unit with narrow molecular weight distribution not more than 1.5 with the set ratio of components is produced. Then the polymer is being ground.
