The regeneration process for zeolite desiccant involves:
Depressurization: Reduce the pressure in the system (if using PSA) to release adsorbed moisture.
Heating: Heat the zeolite desiccant to temperatures between 150°C to 250°C to remove moisture. The heating can be done using air, inert gas, or electric heaters.
Purge: Pass a dry gas (such as nitrogen or air) through the zeolite bed to carry away the desorbed moisture.
Cooling: After the moisture has been removed, cool the zeolite desiccant back to operating temperatures before resuming adsorption.
This thermal regeneration ensures that the desiccant maintains its effectiveness in removing water from gas or air streams.
