It is shown from CFD simulation and particle image velocimetry (PIV) measurements that the flow field around ring packing is impacted by their height/diameter ratio and inclination. The results indicate that it is better to decrease the height/diameter ratio of ring packing to intensify the separation processes in the packing bed. Based on a systematic study, a new Plum Flower Mini Ring (PFMR) was developed to meet the demands of separation column intensification.A comparison of the PFMR, Pall Ring and Intalox Saddle in a 600 mm diameter column with an air–oxygen–water system over a wide range of liquid loads is presented. It was shown from the experiments that the PFMR had a much lower pressure drop, much larger throughput and better mass transfer efficiency than Pall Rings and Intalox Saddles. © 2003 Society of Chemical Industry
