A METHOD FOR PRODUCING A SUSPENSION-TYPE ANTI-TURBULENT ADDITIVE DECREASING HYDRODYNAMIC RESISTANCE OF HYDROCARBON LIQUIDS

摘要

The invention relates to the field of pipeline transportation of liquid hydrocarbons, in particular to methods for decreasing their hydrodynamic resistance. The invention proposes to produce suspensions of higher alpha-olefins without using cryogenic comminution as well as without using polymer precipitation by adding a non-solvent to a polymer solution. According to the proposed method, fine polymer dispersions are produced by thermal re-precipitation of a polymer in a liquid being a non-solvent for that polymer at room temperature and being capable of dissolving it at a higher temperature. The polymer component of a suspension is produced by co-polymerization of higher alpha-olefins in a monomer mass in the presence of a Ziegler-Natta catalyst.
