Pipeline Drag Reducing Additives

Pipeline drag reducing additives are high molecular weight polymers (20-30 mio molecular weight) of octene or dodecene or polyacrylamide suspended in hydrocarbon solvent.

When fluids travel through a pipeline, a velocity profile is developed in the flow that varies from zero velocity at the wall of the pipe to a maximum velocity at the centerline of the pipe. This profile is caused by the flow properties in the fluid that create shear layers.
