Evaluation of Amna Crude Oil

This assay is a part of a series of crude oil evaluation reports have been prepared for Crude oil marketing department of National Oil Corporation. A bout 60 Liters of Crude oil sample was collected from Sirt oil Company. A homogenous sample has been collected on 4 th August 2008 from shipping line at Rasslanuf terminal, the sample was collected according to standard method ASTM D4057. The analysis of crude oil sample was carried out using well recognized standard procedures given in ASTM, IP and UOP methods. The distillation of crude oil was carried out using a batch fractionation unit made according to ASTM D-2892 method & ASTM D-1160 method. The crude oil was distilled under atmospheric and vacuum pressure and the atmospheric residue was further distilled to obtain distillate fractions. Distillate fractions corresponding to true boiling point up to 550+0C were collected.
