Abstract:

Distillation of methanol from methanol-water mixture has been carried out with a rotating packed bed. Having an inner diameter of φ58mm, an outside diameter of φ118mm and an axial depth of 40mm. Experimental results showed that the theoretical plate number of the rotating packed bed increases with the increase in the gas-powered factor F and the gravity factor β at low speed zones, the height of the mass transfer unit is 0.9 ~ 1.2 cm. A model for the mass transfer has been established .
