Absorbent treated process of maleic anhydride device by n-butane oxidation and the principle of Podbielniak centrifugal contactor were introduced. The effects on PODs separated result by temperature, stir rate, oil and water ratio, anhydro were studied. The result indicated that POD separated result were agree with the de-mand when temperature 58℃, stir rate 75 r/min, oil/water ratio 5∶1, anhydride content less than 1. 0%. Separa-tion of oil and water could be achieved in a POD that 0 . 45% oil in the wastewater and 0 . 95% water in the treated oil.
