Abstract

The mass-transfer efficiency of a new vapor-liquid contactor-Rotating Packed Bed(RPB) was studied.Distillation experiment was doing with the ethanol-watersystem,in RPB that contained a rotor,with an outside diameter of 180mm,an inside diameter of 60mm,axial depth of 40mm.The result showed that the mass-transfer efficiency of RPB increased correspond to the F and β in low rotating speed.The height of mass-transfer unit(HTU) was (1.09)～1.76cm and its mass transfer model was developed.
