Question

Describe the process of ‘Chemical dehumidification’.

Hint:

Chemical dehumidifiers use desiccants to absorb moisture directly!

Answer 1

Chemical dehumidification is a method of removing moisture from air using chemical substances called desiccants.
In this process, moist air passes over or through materials like silica gel, activated alumina, or calcium chloride.
These chemicals absorb or adsorb the water vapor from the air due to their high affinity for moisture.
This reduces the humidity level in the air and makes it suitable for applications that require dry air.
Chemical dehumidifiers are commonly used in industries, storage areas, and air conditioning systems where precise humidity control is needed.
Unlike cooling-based dehumidification, chemical dehumidification does not rely on refrigeration cycles.
