“…Außerdem wird Schaum als Ursache oft nicht erkannt, wobei davon häufig Kolonnen betroffen sind. In einer Feldstudie von Kister zu 31 Fehlfunktionen in Kolonnen rangieren schaumbedingte Betriebsprobleme mit 51 von über 900 Fällen auf Platz 11 [1].…”

Experimental Investigations of Foam in Packed ColumnsFoam in process engineering can cause severe problems in distillation and absorption towers. Presently, hydrodynamic models cannot consider foaming in respect of process dimensioning. In a proceeding research project, the fluid dynamic performance data (pressure loss, flooding point) of several different mass transfer packings are examined for foaming material systems. The respective origin of foam generation in the packed column is observed separately. A test cell for the qualification of potential foaming material systems adapted on the special demands of packed columns is introduced. Details on the results on the phenology of foaming, on the fluid dynamic performance data of the column operation with foaming material systems and on the experiments of the adapted test cell are given.

“…Fouling is the undesired formation and accumulation of deposits on surfaces (see Figure 7.8). It is a main factor for malfunction of vaporeliquid separation towers [43]. Deposits decrease the free cross-sectional area for vapor and liquid flow, which in turn increases gas velocity and pressure drop.…”

“…If the liquid distribution is not homogeneous over the column crosssectional area, the separation efficiency is noticeably reduced, as indicated by Moore and Rukovena [26]. In Kister's failure list for column troubleshooting cases, distributor design failures are ranked at number six [27].…”

Since university research on mass transfer columns has decreased significantly in recent years, it is discussed whether the current knowledge of mass transfer technology for trays, packing materials, and column internals is sufficient to design energy-and cost-efficient systems. Points of view are described that have not yet been clarified from an industrial position and should play an important role in future research. In addition to the thermodynamics of industrially relevant systems, an improved description of the fluid dynamics and mass transfer efficiency in trayed and packed columns is included. Research should focus beyond ideal test mixtures which employ standardized test equipments and test systems. Industrial parameters such as foams and solids as well as chemical and catalytic mass transfer are also of great interest.
