| Abstract | ||
| This work studied the facilitation of the transportation of Missan heavy crude oil characterized with high viscosity 84.61 cp at 15 °C, low API 23.1, by reducing its viscosity from break down asphaltene agglomerates using five solvents with some novel combinations of chemical additives were used for this study (naphtha & toluene, naphtha & xylene, naphtha & kerosene, toluene & kerosene, and xylene & kerosene).The viscosity of crude oil was measured after being treated with these chemicals at different concentrations (4, 8, and 12 weight%) and temperatures 15, 25, 35, and 45 °C. It has been found that increasing the concentration of naphtha with xylene from 4% to 12% causes a decrease in viscosity, from 48.62 cp at 15°C to 30.11 cp. The viscosity of a mixture of naphtha and kerosene drops from 50.15 cp at 15°C to 31.70 cp when the concentration is raised from 4% to 12%. The addition of toluene to kerosene causes the viscosity to drop from 51.76 cp at 15°C to 33.67 cp when the concentration of toluene is raised from 4% to 12%. Increasing the xylene concentration from 4% to 12% in kerosene led to a decrease in viscosity from 53.65 cp at 15°C to 34.88 cp at the same temperature. The findings of the present work could be applied to the petroleum industry for the purpose of transporting heavy oil of Missan or any other heavy crude. | ||
