    • Fine particulate polymer drag reducing agents (DRAs) in bi-modal or multi-modal particle size distributions may be produced simply and efficiently without cryogenic temperatures. The grinding or pulverizing of polymer, e.g. non-porous poly(alpha-olefin) suitable for reducing drag in hydrocarbons may be achieved by the use of at least one liquid grinding aid and at least two grinding processors in series. The blades of the stators of the grinders are of different configuration so that granulated polymer fed to the first processor having relatively larger gaps between blades is ground to an intermediate size which is fed to the second processor having relatively smaller gaps between blades which grinds the polymer to a second, smaller size. A non-limiting example of a suitable liquid grinding aid includes a blend of propylene glycol, water and hexanol. Particulate DRA may be produced at a size of 300 microns or less in only two passes.

    • A method of extending or broadening the effective time of drag reduction for a drag reducing agent in a pipeline may be custom-designed by combining two drag reducing slurries or other drag reducing products made by different or alternative techniques. For instance a precipitation polymer slurry derived from polymer precipitation where the polymer dissolves relatively quickly can be combined with a ground polymer slurry derived by grinding bulk polymer (ground at either cryogenic or non-cryogenic temperatures), or by using other size reduction techniques, where the latter polymer dissolves relatively slowly. In one non-limiting embodiment of the invention, bulk polymer may be ground directly into a precipitation polymer slurry to make the ground polymer slurry and blend the slurries simultaneously, where the precipitation polymer slurry serves as an anti- agglomeration agent.
    • 可以通过组合两种减阻浆料或通过不同或替代技术制造的其它减阻产品来定制延长或扩大管道中减阻剂减阻的有效时间的方法。 例如,衍生自聚合物沉淀的沉淀聚合物淤浆,其中聚合物相对较快地溶解,可与通过研磨本体聚合物(在低温或非低温温度下研磨)衍生的研磨聚合物浆料组合,或通过使用其它尺寸减小技术,其中 后一种聚合物相对缓慢地溶解。 在本发明的一个非限制性实施方案中,本体聚合物可以直接研磨成沉淀聚合物浆料,以制备研磨聚合物浆料并同时混合浆料,其中沉淀聚合物浆料用作抗附聚剂。
