Design of Optimal Process Flowsheet for Fractional Crystallization Separation Process

A procedure is presented that synthesizes fractional crystallization separation processes to obtain pure solids from multi-component solutions. The method includes a procedure to generate a network flow model to identify alternative process designs for fractional crystallization. The main advantage of this systematic procedure with respect to other reported procedures is using non-equilibri...

Isothermal Melt Crystallization Kinetic Behavior of Poly (vinylidene fluoride)

Isothermal melt crystallization kinetics of PVDF was investigated by differential scanning calorimetry. Thin PVDF film has been fabricated by the solvent casting technique using dimethylformamide (DMF). Then, the samples were melted and subsequently crystallized in the range of the crystallization temperature (Tc) between 138 and 145 °C. The crystallization kinetics was derived from Avrami equa...

Development of Crystallization Strategies Using the Biological Macromolecule Crystallization Database

The NIST/NASA/CARB Biological Macromolecule studies requires not only finding suitable chemical agents Crystallization Database (BMCD) contains crystal data that induce and sustain crystal growth but also that those and crystallization conditions for biological parameters such as protein concentration, ionic strength, macromolecules abstracted from the literature. Each temperature, pH, etc., be...

Purification of Erythromycin by Antisolvent Crystallization or Azeotropic Evaporative Crystallization

Crystallization plays an important role in separation and purification of the antibiotics. And it is also an indispensable step in preparation of pharmaceuticals with biological activities and specific crystal form. As the last step in purification, crystallization determines the puri‐ ty, crystal habit, granularity and its distribution as well as pharmacologic effect, biologic ac‐ tivity and p...
