Process Engineering Laboratory II Crystallization - ETH Z

Description of the crystallization setup The crystallization is conducted in a thermostated, 250 ml jacketed glass reactor (see gure 4(a)) equipped with a stirrer. A thermostat pumps a mixture of glycol and water through the jacket and uses a Pt100 thermocouple positioned in the reactor to control the reactor temperature.

Mechanisms of Ice Crystallization in Ice Cream Production

Feb 16, 2010 Still, some elements of the crystallization mechanism are well accepted. Because of the large supercooling at the freezer wall, ice nucleates there before being swept into the bulk of the freezer. In the bulk, heat and mass transfer cause some crystals to melt and others to grow. By the time the ice cream reaches the freezer exit, the ice ...

Oiling Out in Crystallization Liquid-Liquid Phase Separation

Oiling Out in Crystallization Liquid-Liquid Phase Separation

Identifying oiling out in crystallization requires the ability to robustly detect the undesired oiling out particle mechanism. Like nucleation, oiling out causes turbidity in a crystallizer and traditional methods (human eye or turbidity sensors) either miss the event, mistake one for the other, or struggle to distinguish between them when they occur simultaneously.

In this review, we highlight particle based crystallization pathways leading to single crystals via mesoscopic transformation. In contrast to the classical mechanism of atom/molecule mediated growth of a single crystal, the particle mediated growth and assembly mechanisms are summarized as non-classical crystallization, including exiting processes like oriented …

Jan 25, 2006 A bstract: In a previous paper, 1 we proposed a complete model for methane hydrate crystallization from pure water and methane gas in a semibatch reactor. This model takes into account the crucial importance of the rate-determining mass transfer at the gas/liquid interface, coupled with primary nucleation and growth.
