DRAG REDUCTION TESTS WITH A POLYMERIC ADDITIVE IN CRUDE OIL PIPELINES

Tests over a 28 mile segment of 8 in. crude oil pipeline at normal flow velocity of 6 ft/sec gave drag reductions of 16, 21, and 25% for polymer concentrations of 300, 600, and 1000 ppm by volume. When the flow velocity was decreased, the drag reduction also decreased. A further test in 32 miles of 12 in. pipeline gave similar results. In none of the tests did the polymer appear to degrade or lose effectiveness because of turbulent shear in the lines. Laboratory tests in a 1 in. ID pipe viscometer for the polymer and various polyisbutylenes covered a range of concentrations and flow velocities, with results showing the same general characteristics as in the large pipelines. An equation which correlates the 8 in. and 12 in. pipe data as a function of flow velocity and polymer concentration is presented.
