Rotating packed bed is a new high efficient equipment for multiphase flow transference, it has been widely used in chemical separation and preparation of nano-materials. The gas pressure drop of RPB is one of important indicators which are used to measure performance of RPB. In this paper, the experimental and simulative progress of research on the gas pressure drop at home and abroad in recent years is reviewed. All kinds of gas pressure drop experiments and simulations of counter-flow RPB, cross-flow RPB are introduced and compared, followed with the analysis of the progress, existing problems, the trend and emphasis.

The Cross

The cross-flow rotating packed bed (RPB) has attracted wide attention in recent years because of its advantages of large gas capacity, low pressure drop and lack of flooding limitation. However, the complex structure of the packing makes it difficult to obtain the gas flow characteristics in the cross-flow RPB by experiments. In this study, the dry pressure drop in the cross-flow RPB was investigated by computational fluid dynamics (CFD). The packing was modeled by the porous media model and the rotation of the packing was simulated by the sliding mesh model. The simulation results obtained by three turbulence models were compared with experimental results, and the RNG k-ε model was found to best describe the turbulence behaviors in the cross-flow RPB. Then, the effects of gas flow rate and rotating speed on dry pressure drop in different parts of the cross-flow RPB were analyzed. The results of this study can provide important insights into the design and scale-up of cross-flow RPB.

The Given

Based on the vapor-liquid equilibrium principle, a new rotating packed absorption tower was presented against some traditional gas-liquid countercurrent tower defects. An experimental device was built to test CO2 absorption efficiency in the packed absorption tower under the given experimental conditions. The experimental results show that the new packed absorption tower can capture the simulated flue gas CO2 and have a higher efficiency 87.8%.
