For packed distillation columns, maldistribution is by far the most important factor that has a negative influence on performance, especially efficiency. The amount of maldistribution related publications is enormous. For the maldistribution story th

Fur eine realistische Beurteilung von beliebigen Verteilungen mussen sowohl die Fluktuationen innerhalb des Stromungsfeldes als auch deren raumliche Verteilung berucksichtigt werden. Daher muss eine Kennzahl, die die Qualitat von Verteilungen beschre

Since the evaluation of the homogeneity of a distribution can be subdivided into two parts (magnitude and spatial distribution), a good key value describing the quality of the distribution has to consider both. The value of the coefficient of variati

With an increasing number of vendor supplied design tools for the calculation of packing hydraulics, the basis of these design methods needs to be reliable—reflecting industrial operating conditions as closely as possible. Currently however, differ

Liquid distributors are a key component to optimal performance in packed distillation columns. Their design is commonly based on the drip point density. For modern baffle plate distributors, however this is not appropriate, because the liquid is deli

The analysis of the history of structured packings allows the conclusion that the innovation cycle will become faster. Based on the separation power as an alternative way to represent the performance characteristics an estimate of the next level of w

Gauze and metal sheet structured packing have been in use in countless separation columns for more than 50 years, and vacuum applications have become the unquestioned domain of structured packing. Structured packing is manufactured in various types,

The design of industrial distillation columns involving well-defined systems for which reliable vapor-equilibrium data are available is nearly straightforward. Stage and reflux requirements are calculated and optimized rigorously through the use of p

The influence of gas and liquid phase flow on the separation efficiency of Optiflow has been extensively studied. The tests were performed in a 1 m diameter distillation column with chloro-/ethyl-benzene as test mixture operated at total reflux. Pack
