Wetted wall gas absorption columns can be used to determine the mass transfer coefficients between gases and liquids, essential in the
design of absorption towers. This factor is the most important one to calculate the size of such towers, since they serve as a basis from which
correlations have been developed for packed towers.

A wet film absorption column (or wetted wall gas) consists, essentially, in a vertical tube through which a liquid descends, meanwhile a gas
ascends through it. The gas, when contacting the liquid, is partially spread in it by means of the mass transfer. This process is normally used
to study the mass transfer between two components in two different phases due to the fact that there is an interfacial film between such
phases in the wet film column, unlike other processes. It will be assumed that such superficial area corresponds to the inner surface of such
tube, so that the liquid can be in the shape of a thin laminar film.

The Computer Controlled Wetted Wall Gas Absorption Column (CAPC) allows to determine the liquid mass transfer coefficient and study
the existing relation between the mass transfer coefficient of the liquid film and the mass flow of water. The obtained results can be
compared with the theoretical predictions.

The studied absorption process corresponds to the oxygen-deoxygenated water system, where the oxygen comes from the air and the
deoxygenated air is obtained through a desorption column, where a water current comes into contact with a nitrogen current.
This is a controlled liquid film absorption example; so that the liquid film mass transfer coefficient can be determined for different water

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control
Interface Box + a Data Acquisition Board + Computer Control and Data Acquisition Software Packages, for controlling the process and
all parameters involved in the process.
