Consideration of the absorption process from a physical and industrial viewpoint

Consideration of the Absorption Process from a Physical and Industrial Viewpoint 

Formulation of the volume-related liquid-side mass transfer coefficient k a leaves the questions open, of whether this quantity should be regarded and investigated as such, or as the product of two parameters fet and a independent of one another. Whereas for industrial problems and design criteria only k a is important, for an in depth consideration of the process it is certainly interesting to establish, how the two components of this quantity depend upon the material and process-related parameters, since a deeper insight into this relationship can also provide hints for a directed optimization of the absorption process. 

The following target quantities of the absorption process appear to be of interest  

volume-related liquid-side mass transfer coefficient ki a, 

There are a number of physical and chemical methods for determining ki,as G/(VAc)[s ], which can be subdivided into imsteady-state and steady-state measuring methods, depending upon whether the concentration c of the gas dissolved in the liquid changes with time during the measuring process or remains constant.
