X-ray tomography is used to characterise the liquid distribution in a 0.6 meter diameter and 2 meter height column filled with gas-liquid absorption polypropylene packing elements (Cascade Mini-Ring 1A, Glitsch Benelux). The liquid holdup distribution is determined for liquid flowrates ranging from 1000 l/h to 6000 l/h, that correspond to superficial velocities ranging from 10(-3) to 6 10(-3) m/s, in several cross sections situated at different heights in the packed column. A characteristic length, corresponding to the smallest scale beyond which the packing properties may be supposed statistically homogenous and isotropic, as determined by Means of the autocorrelation function method applied to the images of the solid distribution. Both local and global liquid holdup measurements are satisfactorily modelled by means of a partial wetting model based on a probabilistic approach. [less ▲]

A 'tailor made' computed X-ray tomographic scanner has been developed as a tool for the analysis of the distribution of gas, liquid and solid phases in packed columns. The very good spatial resolution of the scanner has first been assessed by the imaging of objects of known shape and size, called 'physical' phantoms. Images have then been realized on a 0.6 m diameter and 2 m height column packed with Cascade Mini-Ring 1A packing elements, which is a random polypropylene packing designed to be used in absorption columns. The solid phase distribution, leading to the void fraction distribution, has been analyzed on cross-section images of the dry packed column (without any liquid flowrate). The measured value of the bed void fraction is equal to the value provided by the manufacturer. The analysis of the axial profile of void fraction shows that the 'end effect' may be neglected, whereas the analysis of the radial profile evidences the existence of a non negligible 'wall effect'. Images have then been carried out on the packed column irrigated by a liquid flowrate ranging between 0 and 6000 1 h(-1) (0-6.10(-3) m s(-1)). Hold-up values have been measured in different cross-sections of the column and averaged in order to obtain the total hold-up value in the bed. The computed values are in very good agreement with those reported in the literature for similar packing. The dependence of the liquid hold-up on the liquid superficial velocity can be expressed in terms of a power law. The fitted value of the exponent, equal to 0.65, is in the range of exponent values found in correlations of the literature. (C) 1998 Elsevier Science S.A. All rights reserved. [less ▲]
