Experimental Investigation on Extraction of Oxidation Products of Sulfur-Containing Compounds

This work proposes an effective method for extracting oxidized sulfur-containing compounds from gas condensate. The oxidative desulfurization of stable gas condensate was investigated in the presence of Na۲MoO۴, hydrogen peroxide, dibenzoyl peroxide, and air bubbling. The oxidation products were extracted from the oxidized gas condensate using aluminum oxide, silica gel, sulfonated charcoal, activated carbon, and zeolite NaA and NaX, or by extraction with acetone, acetonitrile, N-methylpyrrolidone (N-MP), and N,N-dimethylformamide (DMFA). The combination of gas condensate oxidation followed by adsorption purification using ASCG silica gel or extraction purification with N,N-dimethylformamide allows for a reduction in total sulfur content from ۷۵۴۰ ppm to ۶۸۰ ppm and ۸۴۵ ppm, respectively.
