Modeling and Experimental Study on Gas Pressure Drop of a Cross-Flow Rotating Packed Bed

The gas pressure drop of a cross-flow rotating packed bed was an important indicator for its engineering application and design.Modeling and experimental analysis were studied on the gas pressure drop with air-water system in a pilot scale in which the gas flow rate was varied from 0to 1 300m3/h and liquid flow rate was ranged from 0to 7m3/h.Results show that the gas pressure drop increases with gas velocity and super gravity factor obviously.It is linear relationship between super gravity factor and gas pressure drop.Increasing liquid spray density increases gas pressure drop but the trend is more evident with larger gas velocity or lower super gravity factor.The correlative expression of gas pressure drop of a cross-flow rotating packed bed in which the parameters are determined by fitting the experimental data is obtained and this provides the basis for calculating the gas pressure drop of a cross-flow rotating packed bed.
