In addition to thermal regeneration, it is important to consider the specific operating conditions and the properties of the zeolite itself when choosing a drying method. For example, it can be useful to evaluate:
Particle size and shape of the zeolite, since fine grains heat up faster but may create higher flow resistance;
Degree of saturation or contamination, which affects the required temperature and regeneration time;
Energy and operational constraints, such as the availability of dry purge gas or the possibility of heat recovery.
In some cases, combining a preliminary purge with dry gas at a lower temperature followed by thermal regeneration can reduce overall energy consumption and shorten the process time.
