Abstract
Embodiments of the present disclosure generally relate to a drag reducing suspension capable of dissolving in cold hydrocarbon fluids at usage level. In one embodiment, the drag reducing composition comprises a drag reducing polymer, a partitioning agent comprises a one or more of a coal-tar resin, a C5 aliphatic petroleum resin, a C9 aromatic petroleum resin, C5/C9 aliphatic/aromatic petroleum resin, a cycloaliphatic diene-based petroleum resin, a pure monomer resin, a terpene resin, a terpene phenol resin, a styrenated terpene resin, a rosin resin, a rosin resin derivative, one or more of an alkylphenol resin, a modified alkylphenol resin, and fully or partially hydrogenated form thereof, and suspending fluid medium. The partitioning agent has a good solubility (greater than 8 ppm) in a hydrocarbon stream, such as in a cold refined hydrocarbon stream, for example a diesel stream at a temperature of 0° C. or less.
