Abstract: According to the structure of Mellapak type packing, liquid flow and mixing mechanisms were analyzed in gas-liquid counter-contacting packed column. A new liquid flow distribution mathematical model , specific for Mellapak type packing columns, was presented. Experimental data of the liquid flow distribution measurements agreed quite well with the theoretical prediction. Furthermore, the effects of gas initial maldistribution and gas load on liquid flow distribution were discussed, and the wall zone liquid flow was preliminarily studied.
