摘要： This invention relates to drag reducing agents used in case of transportation of crude oil products, in particular, to solid dry poly(meth)acrylate with dry poly alpha-olefins powders based agents. The technical result of the solution involves the preparation of an effective, fast-dissolving, stable solid dry drag reducing agent suitable for use in heavy crude oil. The drag reducing agents compositions have better drag reducing performance in heavy crude applications as compared with traditional drag reducing slurries is also disclosed, which consists of the following components, wt %:



a mixture of at least two drag reducing polymers, from 65 to 90
a separating agent from 3 to 25
anti-agglomerating agent from 3 to 25
a surfactant from 3 to 25,
where the first polymer is poly(meth)acrylate, the second polymer is poly alpha-olefin, the ratio of the polyacrylate weight and polyalphaolefin weight varies in the range from 2:1 to 5:1.

摘要： The invention relates to agents reducing the hydrodynamic drag of a turbulent flow of petroleum products in the process of transportation in pipelines. The technical result of the solution involves the preservation of the polymer structure so that the polymer is more effective in reducing the hydrodynamic drag, grinding costs in the production of the DRA, the aggregation of the DRA while reducing the amount of the separating agent and the need to inject a smaller amount of the reagent to reduce the hydrodynamic drag. The specified technical result is produced due to the development of a reagent for reducing the hydrodynamic drag of hydrocarbon liquids in pipelines, which consists of the first and the second component, in which case the first component comprises the particles of polyalphaolefin or polyacrylate, the second component is an anti-agglomerating agent.
