ABSTRACT:
A process for reducing the flowing friction of a liquid hydrocarbon in a pipeline with a polymer soluble in the hydrocarbon by preparing a particulated, substantially undegraded polymer for introduction into a hydrocarbon by mixing the polymer with a solvent, surfactant, and water, whereby the polymer is dissolved, and forming polymer particles in the resulting liquid by flashing off the solvent and injecting the particles into the hydrocarbon.
