Gas-liquid mass-transfer characteristic in cross-flow rotating packed bed with different packings
摘要
Abstract
In order to explore the mass transfer performance of cross-flow rotating packed bed (RPB)with different packings,the experiments on gas-liquid mass-transfer characteristics in a cross-flow RPB loaded with stainless wire mesh packing,plastic corrugated plate packing andθring packing respectively using absorption of H2 S from gas by Na2 CO3 solution were carried out.The appropriate operating conditions were obtained,i.e.high gravity factor 7.8,gas flow rate 2 m3/h,liquid gas ratio 20 L/m3 and the mass concentration of sodium carbonate was 12 g/L. On this condition,the desulfurization rate can reach more than 90%with these different packings.Desulfurization rate and of cross-flow RPB with stainless wire mesh packing were the highest and those withθring packing were the lowest under the same conditions.The gas-liquid mass-transfer performance of cross-flow RPB with structured packing was better than that with random packing.The results provide the basis for selection of packing of cross-flow RPB and its application in desulfuration,and also enrich the Higee techniques of process intensification and offer the basis for the design of RPB.关键词
