Figure 5.5. Floating rotator.

Here is the mass adsorbed on the sorbent mass is the gas mass
between the sorbent pellets moved along with the sorbent and is the
“equivalent” mass of gas in a boundary layer on the surface of the rotator. In
Eq. (5.48) the various relaxation times refer to relaxational motions of the

empty rotator without sorbent material in Vacuum
loaded rotator with sorbent material in vacuum and
loaded rotator in sorptive gas atmosphere
