A local chemical manufacturing company is planning to expand its existing solid

potassium dichromate $($K$2$Cr$2$O$7)$ production line. Instead of using the existing cooling

evaporative crystallization system, a new adiabatic evaporative cooling crystallization

system will be used to recover the solid dichromate crystals from the aqueous

solution.

I$)$ Give an example of adiabatic evaporative cooling crystallization system.

II$)$ Briefly explain the working principle of the example given in $($I$).$

III$)$ List the advantages of using adiabatic evaporative cooling crystallization

system.
