Study of Temperature and Solvent on Quality of Separation and Quantity of Asphaltene in Crude Oil Cuts

Abstract

One of the most important parameters which is used before refining and precepitating asphaltene is the investigation of the quantitation and precipitation process of asphaltene. As a matter of fact, the magority of heavy end distillates is related to asphaltene composition. In this article, the effects of different volumes of solvents such as n-pentane, n-hexane, and n-heptane on the precipitation of asphaltene at different temperatures were investigated. Standard deviations of n-heptane, n-hexane, and n-pentane in the separation of asphaltene at the boiling point and ambient temprature of solvent are (0.25, 0.99), (0.89, 1), and (0.92, 1.2) respectively.
