Abstract

Tray and packed columns are frequently used for the implementation of the unit operations rectification, absorption, and desorption. A maximized phase interface between gas and liquid in these devices is beneficial for mass transfer. Investigations on liquid maldistribution in random packings are conducted in a packed column at varying experimental and operating parameters in terms of type of packing, packing height, liquid distributor, liquid load, and gas load. Graphical presentations in form of distribution spectra and further evaluation by means of a maldistribution factor provide insight into the influence of different parameters on maldistribution.
