Crystallization high-pressure

It should be noted that high-pressure crystallization is not the only means to obtain ECC [26]. It has been... 

Most of the high-pressure crystallization kinetics studies have shown that ECC grows one dimensionally at high pressures [113-116].

High pressure crystallization process has already been applied In Industry to separate a pure substance from a mixture. In this process, pressure Is used for crystallization. Instead of cooling In the conventional method. Although the pressure Is usually applied In Industry so quickly that It reaches 200 MPa In 10 sec, a sufficient amount of crystals can be grown, which results In attaining the separation and refining of a short cycle within a few minutes (U. 

The growth mechanisms of healing were also discussed. It Is believed that these mechanisms discussed above will lead to Important suggestions to study the growth behaviour caused by such rapid pressure application as used In the practical high pressure crystallization.

Advantages of high pressure crystallization are simple control of process parameters, and a solvent-free system. 

Disadvantages of high pressure crystallization are high volumes of solvents, owing to the low solubility of the substances to be crystallized, relatively high pressures, batchwise operation, and long cooling times.
