Crystallization of an organic mixture using spray-evaporation of solvent has been used to obtain solids without liquid. A solid mixture of
lauric acid + myristic acid was dissolved in acetone solvent, and the solution was sprayed through a spray nozzle (100mm I.D.) and evaporated in
a spray column under vacuum. The column was composed of five glass tubes, where powdery solids were collected after spray-evaporation of the solvent.
Weight and composition of the solids on each glass tube were measured at various operating conditions. Most of the solids were collected on the
glass tube nearest the nozzle and also at the bottom of the column. When the composition of solids was analyzed, it was found that the mole fraction
of lauric acid decreased from the top to the bottom of the column.
