    摘要: A hydrocarbon-soluble drag-reducing suspension is described, along with a process for manufacturing the drag-reducing suspension. The drag-reducing suspension is easily transportable, non-hazardous, easily handled, and provides a significant increase in drag-reducing capability over existing products. The drag-reducing suspension is manufactured by grinding an ultra-high molecular weight polymer in the presence of a grinding aid and mixing it with a suspending fluid.

    摘要: The present invention provides a process for precipitating a polyolefin from solution. The present invention also provides a polyolefin paste having drag reducing characteristics when dissolved in a flowing hydrocarbon stream and a method for making the drag reducing paste. Finally, the present invention provides a slurried drag reducer prepared from the paste for use in flowing hydrocarbon streams.
