Exchange Column With Corrugated Structured Packing And Method For Use Thereof

[0189]Cryogenic experiments were performed in a laboratory distillation column with an internal diameter of about 900 mm, corresponding to a cross-sectional area of 0.636 m2. Several packing layers with a surface area density of 500 m2 / m3 were placed on top of each other to create a packed bed height of about 4550 mm. The individual packing layers had a layer height of 103 mm or 207 mm. Two types of experiments were conducted with each packing. In the first type of experiment, all the layers were rotated at an angle of 90 degrees relative to the layers above and below them. In these cases the effective layer height is the same as the corresponding layer height. In the second type of experiment, layers were rotated in pairs, such that the layers within the pair were aligned with each other in terms of the orientation of their respective corrugation elements. In these cases the effective layer height is 2 times the nominal packing layer height of the individual layers and thus 206 mm ...
