“…Deviations between the correlations of different authors available in literature are quite significant, and, considering that these correlations are usually determined experimentally for a certain packing, chemical system, and within a definite range of operating conditions, their extrapolation to other conditions is not a trivial task (cf. [86]). …”

“…Measurements of the liquid film thickness are highly desired since modeling and simulation of the separation column performance often require assumptions on the liquid film thickness and its distribution on the solid structure, particularly in packings of corrugated sheets [21,33,41,42]. Furthermore, the distribution of the liquid phase in the packing cross-section and its local flow patterns, e.g., films and rivulets, contribute significantly to the pressure drop.…”

Design and optimization of separation units, e.g., distillation and absorption columns with flow distribution packings, require detailed knowledge about the internal flow conditions and their impact on the process behavior. This in turn calls for suitable measuring techniques, which can give a detailed insight into such devices, especially for studies on a laboratory and pilot scale. Traditional instrumentation, such as compartment-type liquid collectors installed below packings, or distributed temperature, pressure and conductivity probes, often falls too short if detailed knowledge on flow conditions is required. This concerns especially local liquid holdup, liquid maldistribution, liquid films thickness, wetting of the packing surface, or bubble size and droplet distribution at trays. Advanced imaging techniques, such as tomography, have found only marginal attention in investigations of separation columns with structured and modern dumped flow distribution packings, mostly due to limited spatial and temporal resolution but also due to prevailing technological problems encountered in such applications. In this study, the potentials and limits of some of the most recently emerged tomographic imaging modalities for multiphase flows have been investigated and reviewed, i.e., ultra-fast X-ray tomography, high-resolution gamma-ray tomography, wire-mesh sensor techniques, and X-ray microtomography with respect to a possible application in separation columns with flow distribution packings.

“…In the literature, one can find numerous correlations presented in different forms, however, their application to particular problems often results in significant discrepancies, so that the choice of a suitable correlation is quite tricky. Thus, the strong dependence of the RBA performance on the model parameters represents its week point (see Shilkin et al, 2006).…”
