Distributor drip point pattern

Figure 14-67c shows results of tests in which flows from individual distributor drip points were varied in a gaussian pattern (maxi-mum/mean = 2). When the pattern was randomly assigned, there was no efficiency loss. When the variations above the mean were assigned to a "high zone, and those below the mean to a "low zone, HETP rose by about 20 percent. With structured packing, both random and zonal maldistribution caused about the same loss of efficiency at the same degree of maldistribution.
