Abstract

This work is concerned with the drag reduction using cationic surfactants. (quaternary ammonium amine-sodium salicylate)dissolved in water. Drag reduction measurements were carried out in 6.17 and 2.69 mm diameter tubes, for Reynolds numbers from 101 to 106 and for temperature range of 30o to 120o C. The influence of surfactant composition. Temperature, mechanical shear, concentration and sodium salicylate concentration on the dragreduction were investigated. Trimethyl amine salts are most effective drag reducing agents. While alkyl dimethyl ammonium amine salts are not affective. Length of alkyl group has a major affect on the upper temperature limit for drag reduction.
Appreciable amount of shorter chain reduces the maximum temperature. Concentrations of 1500 ppm of quaternary ammonium amine and 1500ppm of sodium salicylate are needed for affective drag reduction for Czz amines. Cationic surfactants of this type was found to produce higher drag reduction values in the larger tube than that for non-ionic surfactants or for high polymer solutions.
