Rezumat: A detailed analysis of the gas phase maldistribution in packed bed column is carried out based on the experimental data for some random and structured packing at different packing heights. The maldistribution is expressed by the maldistribution factor, calculated from the radial velocity profiles sampled by different number of measuring points. It is shown that by increasing the number of measuring points over the column cross-section the gas maldistribution factor increases gradually but after a definite number of points it does not change more - a “plateau” is reached. This number of the sampling points, respectively the size of the sample area determines the scale of the registered maldistribution – large or small one. This way the different scale maldistributions and the zones where they appear could be identified.
