“…While materials and processes inducing foaming offer a larger surface area for reactions or absorption, excessive foaming can lead to issues like liquid knockouts, reduced efficiency, and increased capital costs. [9][10][11][12] Foaming frequently proves challenging during both the initial conception stage and the subsequent scale-up of emerging technologies like carbon capture using liquid solvents. 2,[13][14][15][16] Thus, managing foaming and identifying essential parameters for foam formation are vital.…”

Foaming prediction is essential for the rational selection of materials and design processes in diverse industries ranging from bioprocesses to gas processing facilities. Existing foaming prediction models lack the generality needed for a wide range of materials and overlook the foaming in pure liquids. This work introduced a novel approach to predict foaming in pure liquids based on their density, surface tension, and viscosity, calculated through Reynolds (Re) and Ohnesorge (Oh) numbers. A foaming prediction map, representing a plot between these numbers, was constructed by leveraging the theory governing the behavior of fluid drops. This map delineated distinct non-foaming regions alongside a foaming region, serving as a binary classifier for foaming predictions. The map was fitted and validated with shake test experiments on 47 liquids, demonstrating effective predictions, except for a specific region characterized by small Oh and large Re numbers. This region corresponded to relatively low foam stability and high turbulence, making predictions challenging for liquids in this category.

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.
