Hygroscopic Material - an overview | ScienceDirect Topics

If a hygroscopic material is pneumatically conveyed, it may absorb moisture from the air that is used to convey the material and become very cohesive, and have poor flowability as a result. Although the specific humidity of the air will reduce if it is compressed isothermally beyond the saturation point, its relative humidity will increase and is likely to be 100% after compression.
