| Abstract: | TBP-Kerosene solution was selected for dephenolization of alkali wastewater in oil refinery. Regeneration of the extraction solvent was very important. Reverse extraction using NaOH solution was chosen to regenerate the extraction solution. Experiments were carried out to find out the effect of different operation conditions on the reverse extraction. The results showed that the reverse extraction system could dephenolize the extraction solution from 58880mg/L to less than 1000mg/L through 3 equilibrium stages. |
