How does the mass transfer phenomenon take place in ACF adsorber bed/any adsorber bed? As per my knowledge chemical reactions also play an important role. If anybody has an idea, please suggest.
Solenoid valves are used to control the flow of mass transfer which are electromechanically operated valves.
For details refer to following document.

Mass transfer as a result of difference in the molar concentration of the transferred substance through each medium in both sides.
The governing law is Fix law of diffusion in rest mediums.(similar to conduction law in HT)
When dealing with moving medium , the governing equation takes into account the Stefani's flow phenomenon associated with bulk fluid motion.(similar to convection law in HT)
Similarity between heat and mass transfer coefficient in case of moving medium.
The driving force here is molar concentration difference.
You also need to know the film theory when dealing with interface between two fluids.
Sensible heat, heat of vaporization and heat of dilution are sources of heat transfer process .
You can find that indetails in "mass transfer operation by Trebal"
In addition to that youneed to estimate the effective interracial area at the interface and correlated mass transfer coefficient based on bed type
