The article shows the expediency of using apparatus for drying compressed air. Adsorption processes with cold and hot adsorbent regeneration are considered. Based on the diagram of air thermodynamic properties, calculations were performed to determine the loss of compressed air during desorption of the adsorbent for a working pressure of 5, 7, 10, 20, 40 bar. The graphical dependences are obtained of compressed air losses on dew point temperature for cold adsorbent regeneration and of compressed air losses on heater temperature for hot adsorbent regeneration. The methods of constructing adsorption isotherms necessary for studying the processes of kinematics and dynamics of adsorption and regeneration are considered.
