Sensors
Sorption equilibria of gases and mixtures on porous solids can
characterized with the measurement of the electric capacity of a with
sorbent filled condenser. The electrical capacity is a function of the
frequency,
of the physicochemical properties of the sorbent and of the dipolar
character of the sorptiv molecules.
Because of this phenomena a sensor was developed. With this sensor it
is possible to measure online the working capacity and
the status of loading of technical adsorbens in plants.
Such informations are useful for controlling of industrial processes:
System for direct and local measurement of loading of
sorbents
Optimization of the cycles for adsorption and desorption
