Nov 08, 2010 · Crystal shapes can include cubic, tetragonal, orthorhombic, hexagonal, monoclinic, triclinic, and trigonal. In order for crystallization to take place a solution must be "supersaturated".  Supersaturation refers to a state in which the liquid (solvent) contains more dissolved solids (solute) than can ordinarily be accomodated at that temperature.
Dear Ajay, I have faced a problem in the plant. I have tried equating a pilot plant (0.1 KL) to large scale reactor(2 KL) reactor for crystallization. Particle size of 40-50 micron. RPM of pilot scale is 15 and plant scale is 8. But there is situation where the material is getting settled at the bottom of the reactor due to low rpm.
