A study of the effectiveness of chemical additives on the characteristic flow of crude oils

Abstract

This article aims to study the effect of the concentration with additives on the kinematic viscosity of crude oils. Additionally, the influence of solvents that reduces the viscosity of heavy oil with significance to their functions in the flow rate of crude oil, which is transported by conveyor pipes to long distances. Different concentrations of polymers with different types named as Polyvinyl chloride (PVC), Sodium dodecyl sulfate (SDS) and Carboxymethyl cellulose (CMC) were tested in order to analyze the experimental data. The results demonstrate that the impact of the additives to the viscosity and comparing at different temperatures. The data can be used to investigate the types of additives that can increase or reduce the viscosity of crude oils. Furthermore, the outcomes show that the addition of PVC at a concentration of (100ppm) and temperature range (30-50 CO) reduces the viscosity of crude oil to the ultimate value the 12.63% at 30Co. However, the viscosity decreases drastically up to (100ppm), and then the amount of viscosity is increased.
