We started with crude oil analyzed by an independent laboratory, Intertek http://www.intertek.com/, a dose of 3% of the W20 fluidifier was added. Such a high dosage was applied to highlight the differences and to compensate the conditions of the extraction of the crude oil from the production well.
Comments
Total Acidity: An insignificant increase of the acidity is observed, which had no impact on the behavior of the crude oil. Crude oil with a T.A.N. <0.05 mg KOH/g is considered non-corrosive.
Kinematic Viscosity: A notable decrease in viscosity was observed. The unit of measurement was equivalent to the measurement in Centistokes (cSt). The decrease registered was of 24.08% over the initial content.
Water and Sediments: A 43.48% decrease in volume occurs and improves the characteristics of the crude oil.
Water: A 44.44% reduction in water content was observed. The previous result was confirmed, which improved the quality of crude oil by decreasing the water content.
Total Sulphur: There was a decrease of 2.38%. The reduction of the Sulphur content means less risk of formation of sulfuric acid and sulfhidric acid. However, the difference is irrelevant.
Asphaltenes: There was a decrease of 10.34% of asphaltenes in the mass of the crude oil. This parameter confirmed the reduction of the kinematic viscosity. The asphaltenes are a cause of the viscosity in the crude oil. The decrease means that the crude oil is easier to transport, it is more fluid, which results in a decrease in energy costs.
