Abstract
In order to investigate mass transfer and pressure drop performance,the new type of self-designed plate packing rotating packed bed (RPB),wire mesh RPB and Pall ring RPB were compared considering the effects of rotating speed,liquid flow rate and gas flow rate.The absorption system NaOH-H2 O and air-water were used as the experimental systems respectively.The mass-transfer experimental results show that under the same operation conditions,the wire mesh RPB has the highest volumetric mass transfer coefficient,and the mass transfer performance of the new type plate packing RPB is close to that of wire mesh RPB (＜ 1.0 s-1);for the pressure drop,the results indicate that gas flow rate is the most effective factor on the pressure drop;in addition,the value of pressure drop of wire mesh RPB is higher than that of Pall ring RPB,and the pressure drop of new type of plate packing RPB is the lowest,meanwhile the percentage difference value of wire mesh RPB and new type of plate packing RPB is more than 33％.The results show that the new type of plate packing RPB has better performance on energy consumption during a small reduction on mass transfer.The results provide the basis for design and improvement of packing structure of RPB.关键词
