Abstract

This study aims to evaluate the effect of different dosages of the PentoMuls- 3C additive on the physical properties of heavy crude oil, specifically API gravity, density, kinematic viscosity, and dynamic viscosity. This aspect is crucial as it allows for the characterization of heavy crude oil behavior, directly impacting the improvement of combustion efficiency parameters, corrosion, and gas emissions. The study begins with the current dosage of 2.5×10⁻⁷ m³ of PentoMuls-3C/kg of fuel and 6% water. An experiment was designed using Statgraphics 19X-64 software, defining the physical properties of the mixtures as dependent variables and the additive concentration (ranging from 1.5×10⁻⁷ to 3.5×10⁻⁷ m³ of PentoMuls-3C/kg of fuel) and water percentage (4–7%) as independent variables. The determination of these properties was carried out following American Society for Testing and Materials (ASTM) standards. The results indicate that API gravity increases and density decreases when using 4% water and 1.5×10⁻⁷ m³ of PentoMuls-3C/kg of fuel. Both kinematic and dynamic viscosity exhibit irregular behavior, with five combinations exceeding the standard limits. These variations should be considered in the design of the heavy crude oil pumping and transfer system, as well as in the combustion system.
