Comparative study of mass transfer performance of different structured packings in rotating packed bed
摘要
Abstract
Mass transfer performance of cross-current rotating packing bed with metallic wire structured packing and novel plastic structured packing respectively was investigated using Na2CO3- H2S as absorption system. The effects of liquid flow,gas-liquid ratio,and high-gravity factor on desulfurization rate and gas phase mass transfer coefficient were studied by theoretical derivation of expressions of gas-liquid mass transfer coefficientsKy andKya. Desulfurization rate of wire packing bed was 3%—4% higher than novel plastic packing bed under the same conditions,but Ky,Kya and pressure drop were 0.25—0.5、0.8—0.9 and 0.3—0.5 times of novel plastic packing bed.Kya of novel plastic packing bed was 1.45 times higher than that of bulk wire packing bed under similar working condition. Correlation ofKy,Kyaand gas phase Reynolds numbersReG,liquid phase Weber number WeL,Galileo numberGa was obtained by regression of experiment data.关键词
