DRYING removes water and other liquids from gases, liquids, and solids. The term is most commonly used, however, to
describe removing water or solvent from solids by thermal means.
Dehumidification refers to the drying of a gas, usually by condensation
or by absorption with a drying agent (see Chapter 22 of the
2001 ASHRAE Handbook-Fundamentals). Distillation, particularly
fractional distillation, is used to dry liquids.
