Sodium Stearate as Drag Reducing Agent in Non-Aqueous Media

H. A. Abdul Bari, R. B. Mohd. Yunus, W. K. Mahmood and Z. B. Hassan

Abstract:
The aim of the present investigation was to decline the solubility condition that number of previous investigation put for any component to be classified as drag reducing agent. In the present investigation, Sodium Stearate (SS) with different concentrations (50 to 300 w ppm) was used. The solvent was used gas oil flowing in three pipe diameters pipelines (0.508, 0.254 and 0.01905 m) and within flow rate range starting from 1.9 to 4.5 m3 h-1. All the experimental work was carried out in a built-up closed loop liquid circulation system with three testing sections (2 m long) of the three pipe diameters investigated. The experimental results showed that, percentage drag reduction (Dr %) increases by increasing the surfactant concentration and Reynolds number. Also, Dr (%) was found to increase by decreasing the pipe diameter. The results proved that, the additive solubility in the transported media is not a condition to classify the chemical as drag reducing agent. Experimental work correlation equation was suggested representing the percentage drag reduction as a function of Reynolds number.
