CFD Study of Gas Flow Through Structured Separation Columns Packings Mellapak 250.X and Mellapak 250.Y
M. Isoz
Abstract:
In order to increase the size of the gas-liquid interface area and consequently the intensity of the mass transfer, the separation columns are usually filled with a geometrically complex packing. The packing highly increases intricacy of the flow in the column and also makes almost all types of hydrodynamic measurements impossible. Hence a reliable model of the flow in the complex geometry of the separation column packing is sought by the industry. We provide a CFD model for the gas ow through two types of commercial structured packings, Mellapak 250.X and Mellapak 250.Y. We validate the model on experimental data and use it to study the gas mixing capabilities of the packings.
