The effect of additives on the properties of crude oil

Abstract

"Crude oil extracted in Romania has different pompability characteristics, depending on their formation period (they can be asphalt or paraffin). One method of improving pompability is that in which various additives are used to reduce the freezing point and/or viscosity. These mixture additives may be polymers or other chemical agents. The role of the additives is to reduce the precipitation of the paraffin crystals in the solution by keeping the paraffin molecules as separate entities. This reduces the cohesive forces between the crystals and the adhesion forces between the paraffin crystals and other surfaces. The vast majority of modifiers proposed as oil depressants are macromolecular compounds. The purpose of this article is to analyze the effect of additives on the property of crude oil. "
