Rezumat: Gas flow distribution in columns with packing Raschig – super ring is studied. So far such studies have been made with packed layer height up to 1.3 m. Of interest is the flow behavior at higher layers, as in this case usually occurs the so called “wall flow”. Experiments are carried out in a column with a diameter of 0.47 m and a layer height to 2.1 m. The measurements were made at three different velocities and the velocity profile is measured by thermo anemometer in 123 points on the column cross-section at different layer heights. The non-uniformity is determined using the so-called maldistribution factor Mf, which takes into account as the velocity value at a point of the cross-section as its weight in the flow. The lowest value of Mf is found at height of 0.5 m and is found that increasing the layer height, the maldistribution begins to rise.
