2、trated that the weeping is mal-distributed and occurs mainly in a region of traydeck next to the inlet weir. The amount of weeping in this region depends on the weeping rate. On this basis, threetypes of weeping distribution are proposed. The effect of mal-distributed weeping on the Murphree tray ef
3、ficiencyis evaluated by using the three-dimensional non-equilibrium mixing pool model, where the influences of the flowpattern and the variation of Murphree point efficiency on a tray are taken into account. The calculated resultsreveal that the extent of Murphree tray efficiency drop depends chiefly on the degree of mal-distribution and thepercentage of weeping. It is also demonstrated that in the determination of the lowest operating limit of
