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.
