عنوان المقالة:تقدير الكبريت الكلي في نفط المسيلة (حضرموت-اليمن) الخام بعد عملية نزع الكبريت باستخدام مادة أكسدة Total Sulfur Determination in AL-Masila (Hadramout –Yemen) Crude Oil after Desulfurization using Oxidative Process
Environmental concerns have introduced a need to remove sulfur‐containing compounds
from oil. As oxidative desulfurization is conducted under very mild reaction conditions, the
present research work is aimed at reducing the sulfur content of AL-Masila (Hadramout –
Yemen) crude oil (0.402 wt.% sulfur content) prior to processing by subjecting oxidation with
hydrogen peroxide in the presence of acetic acid as a catalyst and solvent extraction for
which different solvents have been tested including acetonitrile, acetone and ethanol. The
measured sulfur content of the crude oil, indicated that acetonitrile has higher ability to
extract sulfur compounds (than the other two), at 3:1 solvent/oil ratio. The effects of the
operating conditions (contact time, temperature, mixing speed) on the desulfurization
efficiency were investigated. The desulfurization efficiency measured at the optimum
conditions: 65 0C, 500 rpm, 60 min and 100 ml AL-Masila crude oil, was 39.7%
corresponding to a sulfur content of 0.242 wt.%.
