Levan, a polysaccharide from Zymomonas mobilis, was hydrolyzed to obtain oligofructans or fructooligosaccharides with a degree of polymerization varying from 4 to 14. Fructooligosaccharides (FOS) are short chain fructans that beneficially affects the

Publikováno v: JOURNAL OF CHEMICAL ENGINEERING OF JAPAN. 39:940-947

A one-dimensional model for the crystallization of a binary or pseudo-binary solution was developed. Usually, the Stefan’s problem is associated with the crystallization of melted solids, in which the energy transfer (heat diffusion) dominates the

On the dynamics of nonequilibrium simple batch distillation processes

Autor: A. Knoechelmann, M.R. Wolf-Maciel, Antonio J. A. Meirelles, José Marcos Francisco da Silva, Carlos Edison Lopes

Publikováno v: Chemical Engineering and Processing: Process Intensification. 42:475-485

The study of the dynamics of a simple batch distillation usually assumes the equilibrium between the liquid and vapour phases. In contrast to that approach, this work considers the analysis of the dynamic behaviour of a nonequilibrium simple batch di
