Advanced Separation Processes

For the batch recovery of a compound by cooling crystallization, the following temperature profile is found to ensure that the supersaturation ( c) remains constant throughout the batch at a level of 0.007kg solute /L of solution: The crystal growth and nucleation kinetics for the compound are given by G(m/s)B(#/m3s)=2105c1.1=6107c2 For an initial seed loading of 70g/m3 of solution (seed size =50m ), find the number-based and volume-based average crystal size at each sample time assuming the given temperature profile. The crystal density is 1750kg/m3, while the volume shape factor of the crystals is 0.525
