- The feasibility of removing sulfur from real light gas oil using inorganic liquids (NaOH, Ca(OH)2 and HCl) at various concentrations assisted with ultrasonication was investigated in a continuous flow setup. Experimental results showed that at the optimum operating time (40 min), 68% of sulfur was removed under mild conditions using 10 wt. % NaOH. Ultrasonication not only facilitated sulfur removal but also improved gas oil properties by decreasing density and viscosity by 1.40 and 4.42%, respectively, while the cetane number (CN) was increased by 7.0%. Solute selectivity (S) depending on sulfur mole fraction (xS) was correlated using StatPlus 6.7.1.0 software and the following values have been obtained: S = 53.869e–2.552xs, and S = 29.573 – 41.878xs for mixtures of 10% Ca(OH)2 + S-compound + oil, and 10% NaOH + S-compound + oil, respectively. The correlation coefficients (R2) for the above equations were 0.9813 and 0.9611, respectively. An empirical correlation related to sulfur removal as a function of processing time and solvent concentration was found with R2 = 0.956. The results of the present work confirmed the feasibility of employing the hybrid method of ultrasonication with using alkaline liquids for sulfur removal.
