摘要： A drag reducing composition comprising particles of at least two different drag reducing polymers. The different drag reducing polymers can be formed by different processes, such as bulk polymerization or emulsion polymerization, and the particles of the different drag reducing polymers can have different mean particle sizes. The drag reducing compositions can be added to a hydrocarbon-containing fluid to decrease the pressure drop associated with the turbulent flow of the hydrocarbon-containing fluid through a conduit.

摘要： A drag reducing composition comprising at least one non-polyalphaolefin polymer having an average particle size in the range of from about 5 to about 800 micrometers. The non-polyalphaolefin polymer can initially be formed via emulsion polymerization. The initial polymer particles can then be at least partially consolidated and then reduced in size and suspended in a carrier fluid. The resulting drag reducing composition can be added to a hydrocarbon-containing fluid to decrease the pressure drop associated with the turbulent flow of the hydrocarbon-containing fluid through a conduit.
摘要翻译：减阻组合物，其包含至少一种平均粒度在约5至约800微米范围内的非聚α-烯烃聚合物。非聚α-烯烃聚合物最初可以通过乳液聚合形成。然后可以将初始聚合物颗粒至少部分固结，然后减小尺寸并悬浮在载体流体中。所得到的减阻组合物可以加入到含烃流体中以减少与通过管道的含烃流体的紊流相关的压降。

摘要： Liquid water soluble polymer suspensions in non-aqueous solvents are extremely stable over long periods of time with minimum separation of the solvent and no hard packing of the dispersed water soluble polymer. The suspensions enable a user to rapidly add the suspension to water, being mixed at low speeds, without the formation of lumps or fisheyes and without generating fugitive dust in the process. The suspensions are environmentally safe and biodegradable. Unlike many other liquid polymer suspensions, the suspensions exhibit minimal oil or grease upon dilution. They contain no surfactants that can add to the oil and grease determination. The suspensions and the fluids produced by diluting the fluids to a working concentration of the water soluble polymer exhibit low toxicity to marine organisms and to humans. The suspensions can be manufactured from ingredients suitable for use in personal care applications such as cosmetics, shampoos and the like. The suspensions can be manufactured using ingredients suitable for use in indirect contact with food. The suspensions are also pourable at low temperatures. The suspensions are also suitable for use in the formulation of fluids suitable for use in hydraulic fracturing and other well applications.
摘要翻译：在非水溶剂中的液态水溶性聚合物悬浮液在长时间内是非常稳定的，溶剂的分离最小并且分散的水溶性聚合物没有硬包装。悬浮液使用户能够将悬浮液快速添加到水中，以低速混合，而不会形成团块或鱼眼，并且不会在该过程中产生逸散的灰尘。悬浮液是环境安全的和可生物降解的。与许多其他液体聚合物悬浮液不同，悬浮液在稀释时显示最小的油或油脂。它们不含可以添加油和油脂测定的表面活性剂。通过将流体稀释至水溶性聚合物的工作浓度而产生的悬浮液和流体对海洋生物体和人体表现出低毒性。悬浮液可以由适用于个人护理应用例如化妆品，洗发剂等的成分制造。可以使用适合与食物间接接触的成分制造悬浮液。悬浮液也可在低温下倾倒。悬浮液也适用于适用于水力压裂和其它井用途的流体配方。
