6.6.4 Adsorption dryer (chemical method)

Moisture is absorbed by a solid drying agent. Those can be divided both into solid, insoluble drying agents like dewatered lime and magnesium perchlorate, as well as into soluble drying agents like lithium chloride and calcium chloride. Whereas the insoluble drying agents do not liquify after chemical reaction with water vapour the soluble drying agents liquify in case of progressive absorption. It is disadvantageous that smaller particles of the drying agent are absorbed by the compressed air and this might lead to increased corrosion within the system.
