| Abstract: |
| The distribution of different organic sulfides in LPG and C4 of refineries are introduced in this paper. Typical deep desulphurization technologies for LPG and C4 of refineries including thiol desulfurization by fiber membrane, distillation desulfurization,adsorption desulfurizationand and solvent desulfurization are reviewed. Combining gasoline mixing components production 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. |
