| Abstract: | The distribution of different organic sulfides in LPG and C4 of refineries are intro- duced in this paper. Typical deep desulphurization technologies for LPC- and C4 of refineries in- cluding thiol desulfurization by fiber membrane, distillation desulfurization, adsorption desulfu- rizationand and solvent desulfurization are reviewed. Combining gasoline mixing components pro- duction and deep desulfurization of C4, four processing schemes are presented and compared. Considering the facts of investment, whole energy preservation and product market supply, two of the four processing schemes are recommended. |
