Abstract
This work discusses the potential of three multistage zeolite
drying systems (counter-, co-, and cross-current) with a varying
number of stages. The evaluation showed that for 2¿4 stages with
heat recovery the efficiency of the systems ranges between 80 and
90%. Additionally, by introducing a compressor, the latent heat
in the exhaust air from the regenerator is recovered and used to heat
the inlet air for an additional drying stage. As a result, for the
counter-current drying system and compressor pressure 1.5¿2 bar,
a maximum energy efficiency of 120% is achieved, which results
in halving the energy consumption compared to conventional drying
systems.
