Abstract
Apparatus for endothermic dissolutions in water, including: a mixing tank 40, wherein solute is slurried with water; pump 59 and spray pipe 63, for spraying slurry into spray box 70; and fan 75 for drawing ambient air upwardly, in direct heat exchange relationship with descending slurry droplets. Dissolution is promoted, as the droplets extract heat from the countercurrent flow of air.
