✦ Synopsis

An equation for the liquid distribution in a packed column is established by using a diffisiorr al model for the spreading of the liquid in the packing and by assuming that the variation of the flowrate in the wall region is determined by the difference between two flow-rates, one towards the wall and another one returning from the wall.

The predictions of the theory are compared with experimental flow profile for four packings. Though the constants appearing in the theoretical equations were determined independently, by means of experiments achieved in some limiting conditions, the agreement between the theoretical and expehmental distributions is very good.
