METHOD FOR PRODUCING A REAGENT TO DECREASE HYDRODYNAMIC RESISTANCE OF TURBULENT FLOW OF LIQUID HYDROCARBONS IN PIPELINES.

摘要

The invention relates to inorganic and polymer chemistry, and more specifically to the transport of oil and petroleum products via pipelines. A method for producing a reagent to decrease hydrodynamic flow resistance of liquid hydrocarbons in pipelines comprises polymerization of alpha-olefins C6-C14 in the presence of a catalyst and a catalyst activator. Furthermore, the polymerization of alpha-olefins C6-C14 is performed in a monomer medium with the addition of 0.1 to 5 mass percent of saturated alicyclic hydrocarbon composition C8-C32 and a saturated aliphatic hydrocarbon composition C6-C18 with monomer conversion of 96.0 to 99.5 mass percent, wherein microspherical titanium trichloride is used as the catalyst, and a mixture of diethylaluminum chloride and triisobutylaluminum in a mass ratio of 1:10 to 10:1 is used as the catalyst activator. A polymer is then produced with a molecular mass of more than 107 amu with a narrow molecular mass distribution of no more than 1.5 with the specified component ratio. The polymer is then ground, thereby obtaining the commodity form of the reagent for decreasing hydrodynamic flow resistance of liquid hydrocarbons in pipelines. The technical result of the invention consists in producing a reagent that provides a decrease in the hydrodynamic resistance of the flow of liquid hydrocarbons in pipelines and, as a result, increases the throughput capacity of a pipeline and decreases the cost of transport.
