Abstract
The influence of potato starch as natural additive on the flow of heavy crude oil-water in pipeline was investigated. Measured parameters were viscosity, drag, energy analysis and power requirement in a horizontal pipeline at various temperatures, flow rates and concentrations of potato starch. It was found that addition of 2000 ppm potato starch to the 85% Heavy crude oil+15% water mixture at 40 degrees C decreased viscosity by 80.24% and head loss by 7.55 x 10(-4) m at 60 LPM. Drag reduced up to 91% and power saving increased up to 38.24% after adding 2000 ppm of potato starch to same mixture at 60 LPM.
