Melt crystallization of isomeric long-chain aldehydes from hydroformylation

Deterministic global optimization in conceptual process design of distillation and melt crystallization

“…[33,35] The obtained globally optimal objective function value for each flowsheet option is given in Figure 3. The optimization results identify flowsheet option (b) as the cost optimal configuration.…”

“…Although an additional stage is used, the objective function value is reduced by over 2 % by using the alternative design. This behavior is not obvious and necessitates the A c c e p t e d M a n u s c r i p t [33,35] following, more detailed study of the model. The more detailed study will also show that savings over 25 % are possible.…”

“…Liquid inclusions in the crystals have to be considered. See [33,34,35,36] for more details on the properties of this mixture.…”

Chiral Separation of the Phenylglycinol Enantiomers by Stripping Crystallization

“…As opposed to the solid–liquid transformation in melt crystallization operated at normal pressure during the cooling process [ 22 , 23 , 24 , 25 , 26 , 27 ], the three-phase transformation occurs in SC at low pressures during the cooling process. Thus, SC combines melt crystallization and vaporization to produce a crystalline product and mixture vapor from a mixture liquid or melt [ 17 , 18 , 19 , 20 , 21 ].…”

The Dependence of Effective Distribution Coefficient on Growth Rate and Mass Transfer Coefficient for P-Xylene in Solid-Layer Melt Crystallization

“…Traditionally, two modes, including the static melt crystallization and falling film melt crystallization, have been widely applied in industries. A number of studies have been published to model the crystal layer growth and impurity distribution processes for various types of solid-layer melt crystallization [6][7][8][9][10][11][12][13][14][15][16]. Basically, in these models, the fundamental energy balance and mass balance equations at the moving crystal layer surface are developed to determine the increase of the solid layer thickness and impurity distribution along the time with sufficient thermal property data.…”
