Computer Controlled Wetted Wall Gas Absorption Column

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.
