Abstract:
A drag reducing composition comprising at least one non-polyalphaolefin polymer having an average particle size in the range of from about 5 to about 800 micrometers. The non-polyalphaolefin polymer can initially be formed via emulsion polymerization. The initial polymer particles can then be at least partially consolidated and then reduced in size and suspended in a carrier fluid. The resulting drag reducing composition can be added to a hydrocarbon-containing fluid to decrease the pressure drop associated with the turbulent flow of the hydrocarbon-containing fluid through a conduit.
