  Abstract:  New bench scale measurements of the gas-side pressure drop have been carried out using columns equipped with two different packings: conventional Raschig rings, and a structured packing of Mellapak 750 Y type. The pressure drop per unit height, at the same loading, was about twenty folds smaller in the structured packing. The data have been further correlated on the basis of a new fluid-dynamics model, valid for any type of packing. It has been found that the packing constant Cp is not dependent only on the texture of the packing. It linearly increases with the liquid load.
