权利人:LIQUIDPOWER SPECIALTY PRODUCTS INC
摘要:A drag reducing composition, methods of forming a drag reducing composition, and methods of using a drag reducing composition to reduce the pressure drop of a liquid hydrocarbon through a conduit are provided. The drag reducing composition includes a latex polymer, a cationic surfactant, optionally a nonionic surfactant, and a continuous phase. The cationic surfactant is selected from quaternary ammonium-based cationic surfactants, imidazolium-based cationic surfactants, pyridinium-based cationic surfactants, or a combination thereof.
