Friction reducing additive scale-up experiments were carried out with 200 wppm Separan solution and 2000 wppm Kemamine solution in a test section with a nominal pipe diameter of 6.0 inches and a length of 70 feet. The experimental results of pressure drop tests of Separan and Kemamine indicate that the friction reduction is not affected by pipe size when the solution is fresh. However, short-term degradation tests show that the high molecular weight polymer solution degrades completely due to the high pump shear and aging, while the surfactant solution does not lose its friction reduction effectiveness because of the high pump shear and appears to have a long lifetime. 9 refs., 8 figs.
