This simulation shows mass balances for an evaporative crystallization process. A 15% potassium chloride/85% water feed is mixed with a recycle stream and fed to an evaporator, which evaporates water and increases the KCl concentration in the exiting solution.

Evaporation requires heat (or air movement above the sample) to drive off a volatile solvent. If the substance is a solid mixed in a solvent, begin by filtering (or decanting). If the substance is dissolved in a solvent, then use …

Evaporative Crystallization. The evaporation of the solvent causes crystallization in evaporative crystallization. As a result, this technique produces vapor and a crystal suspension in mother liquor. The extra heat of evaporation …

Evaporative crystallization. Crystallization of MnSO 4 ∙H 2 O from the produced stripping solution was performed in a rotary evaporator (RE150–220, Labfirst Scientific, China), at 50°C and 50 mbar. The obtained crystals were washed multiple times with ethanol (95%) to remove traces of liquid residues and dried at 50°C before analysis.

evaporative crystallization process using hot air as con - tact phase with the solution. The process is carried out in a bubble column crystallizer. Air is heated usually by an electrical heater or by contacting with other heating agents. Hot air of a flow rate (L) is brought into contact

engineering approaches to crystallization have paved the way in the analysis of crystallizer design and operation. The most important aspect of system behavior is the characterization of crystallization kinetics. Crystal growth and nucleation are the two important rate processes, agglomeration occasionally being consid­ ered.
