Abstract
Abstract The aim of the present work was to determine the extent of gas maldistribution in large-diameter columns containing corrugated-sheet structured packings. A large-diameter column simulator has been designed for this purpose (cross section, 3 m × 0.5 m; packed bed height, 4.4 m) with 15 independent inlets for gas, allowing the introduction of diverse initial distribution profiles. The gas velocity profiles leaving the top of the packed bed are discussed in terms of lateral spreading and observed effects of gas load, liquid load and the height of the packed bed.
