2004-11-9 · The product mean size does not exhibit a clear dependence on reactor size, but depends more strongly on other parameters. Results from experiments from 1 L scale to 200 L scale can be correlated fairly well against a dimensionless nuer defined as the ratio of the total time of reactant feeding to the time constant of mixing.
2009-1-10 · Crystallization is a process of mass transfer of the solute from the liquid phase to the surface of crystal particles. Crystallization is the reverse process of solution, to dissolve a solid in a liquid. To crystallize the solute in a liquid solution, the solution needs to be concentrated to supersaturation, which can be achieved in three ways,
