Non-cryogenic process for granulating polymer drag reducing agents |
摘要 |
A method for producing a particulate polymer drag reducing agent, comprising granulating a bulk polymer DRA having an average size of greater than about 100 mm in the presence of a liquid wetting agent to form a granulated polymer DRA having an average size of from about 1 to about 100 mm. The granulated polymer DRA may then be ground to form a particulate polymer DRA having an average particle size of less than about 1 mm. The "wet" granulation process may advantageously enable one-step granulation and therefore simplified production of polymer DRAs. Examples of the liquid wetting agent include blends of glycols with water and/or an alcohol. Preferred production apparatus includes use of multiple rotary jaws for the granulation.
