Fractionation and characterization of Crude Oil Components from Al-Rashidiya Field - Eastern Baghdad using Chromatography Method

Abstract

Study and separating of crude oil components from Al-Rashidiya field-Eastern Baghdad-Iraq was achieved. Samples were taken and separated into two important parts Asphaltene and Maltin (saturated, aromatic and resin). The separation was done by organic solvent such as n-hexane. Maltin separated by column chromatography technique (liquid-solid) to basic saturated, aromatic and resin components, this technique called (SARA) (saturated, aromatic, resin and asphaltene). Three absorption layers used, alumina layer Al 2 O 3 , silica SiO 2 and combination layer from Al 2 O 3 and SiO 2. All the components were collected dried and weighted. In order to determining the classification types, isolated compounds
