Abstract
In a gas dryer for use in a gas transmission line in which a bed of desiccant tablets is suspended in the flow of gas, making an aqueous solution of the desiccant salts from the moisture taken from the gas, the solution is inhibited from generating solids and precipitates in a sump area by conducting the heat of hydration from the bed area to the sump area.
Claims18
Method of inhibiting the formation of solids in a solution of desiccant salts obtained by drying flowing gas comprising moving an agitator in said solution wherein said agitator is moved by the force of said gas.
Method of inhibiting the formation of solids in a solution of desiccant salts obtained by drying gas by contact of said gas with solid desiccant salts, comprising recovering heat of hydration generated by the removal of moisture from said gas during contact with said solid desiccant salts, and transferring the heat of hydration generated by said contact to said solution.
Apparatus for drying gas in a gas transmission line comprising a vessel including a chamber for holding a bed of solid desiccant, and means for transferring heat of hydration from said bed of solid desiccant to a sump for a used desiccant salt solution.
Apparatus for drying gas in a gas transmission line comprising a vessel including a perforated plate for holding a bed of desiccant tablets, a sump area for holding used desiccant solution, and means for transferring heat from said bed of desiccant tablets to said sump area.
