Soluble or deliquescent type (e.g., calcium chloride, etc.):
(under subclass 108) Apparatus in which the solid sorbent dissolves in the constituent retained or sorbed therein or thereon.
(1) Note. Soluble sorbents of this type are usually composed of a metallic salt or brine material used to retain liquids or condensable gases from a gaseous fluid mixture.
(2) Note. These soluble type sorbents are also called "hygroscopic" materials since they are frequently used to remove moisture from a contacting gaseous fluid mixture.
