Comparative Study of the Effect of Aromatic and Aliphatic Compounds and New Formulations on the Viscosity of Crude Oil

The objective of this study is to find out how much the viscosity of oil is reduced by a combination of chemical compounds and two separate compounds at 20 °C, 30 °C, and 50 °C. Toluene, ethylbenzene, para-xylene, ortho-xylene, and mon-xylene are aromatic compounds that make up the first formula (A).Formulation B is composed of aliphatic and aromatic compounds: propane, xylene, acetone, and toluene. The compounds dimethylsulfoxide and tetrahydrofuran were used independently. All the compounds and formulations used in this study were added at 3000, 6000, 9000, 12000, and 15000 ppm. The obtained results clearly demonstrate the efficacy of combining these compounds. The order of viscosity effects is Blend A > tetrahydrofuran> dimethylsulfoxide > Blend B, and the amount of viscosity reduction depends on temperature and the amount of additives. The modeling adopted indicated that the flow has a non-Newtonian character, following the Herschel Buckley model. With the addition of additives, the crude oil viscosity decreased by 74.78%, followed by a decrease in the pressure drop and the energy consumption of a pump. The yield stress also decreased by 42% at a well-determined concentration and temperature. The viscoelastic study showed that the additive had a big effect on the G" modulus, though not as big as the effect those chemicals had on the G' modulus.
