| titleOfInvention | Separation and removal of sulfur oxides from sulfur oxide containing high boiling fraction |
| abstract | The present invention provides a method for separating and removing sulfur oxides from sulfur oxide-containing high-boiling fractions produced in the oxidative desulfurization process, and (S1) supplying an extraction solvent to sulfur oxide-containing high-boiling fractions to remove unreacted oxidants and oxidation by-products. An extraction step, wherein the extraction solvent is methanol or acetonitrile; (S2) extracting solvent removing step of removing the extracting solvent by distillation; And (S3) a method for separating and removing sulfur oxides from a sulfur oxide-containing high boiling fraction comprising an adsorption step of adsorbing and separating sulfur oxides in the sulfur oxide-containing high boiling fraction using an adsorbent. According to the present invention, if the extraction step using methanol or acetonitrile as the extraction solvent and the extraction solvent removal step prior to the adsorption step in the sulfur oxide separation process specialized for high boiling point fractions are carried out in an economical manner, Spot fractions can be prepared. |
