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 Al2O¬3, silica SiO2 and combination layer from Al2O3 and SiO2. All the components were collected dried and weighted. In order to determining the classification types, isolated compounds were studied spectrally using NMR spectrum (13CNMR, 1HNMR) by identify structures of separated materials.
