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 .

摘要：

以甲醇-水混合液为物系，对转子内径为φ58 mm、外径为φ118 mm、高40 mm的旋转填料床进行精馏实验。结果显示，在低转速区旋转填料床的理论塔板数随气相动能因子F和超重力因子β的增大而增大，传质单元高度为0.9～1.2 cm；并建立了传质模型。
