摘要
The hydrodynamics and mass transfer of Plum Flower Mini Ring (PFMR), Pall Ring and Intalox Saddle were studied in a 600 mm diameter column with air-oxygen-water system over a wide range of liquid loads. It was shown from the experiments that PFMR had much lower resistance, larger throughput and higher mass transfer efficiency than Pall Ring and Intalox Saddle. It was clear from the comparison that existing equations could not predict the performance of packings very well at high liquid loads. Therefore, new semi-empirical equations of pressure drop, flooding gas velocity and height of transfer unit (HTU) were proposed based on the experimental data.
