Title
(EN) SPINNING DISC REACTOR WITH PERMEABLE SUPPORT ELEMENT FOR CROSS-FLOW FILTRATION OR SOLVATION
(FR) REACTEUR DE DISQUE TOURNANT MUNI D'UN ELEMENT DE SUPPORT PERMEABLE POUR FILTRATION A CONTRE COURANT OU SOLVATATION
Abstract
(EN)
A reactor apparatus including a support element rotatable about an axis, the support element having an exposed, external surface generally centred on the axis and an internal surface opposed to the exposed surface. The exposed surface is adapted for outward flow of a thin film of a fluid phase component thereacross when supplied thereto as the support element is rotated. At least a portion of the support element is permeable or semi-permeable or porous so as to allow passage of liquid or gas phase components therethrough between the external and internal surfaces but to prevent passage of micrometre-scale particles therethrough. The reactor can be used for crystallisations or precipitations from solution while preventing scale inhibition on the external surface, or may be used for cross flow filtration applications.
(FR)
L'invention concerne un réacteur comprenant un élément de support tournant autour d'un axe. L'élément de support présente une surface extérieure exposée, généralement centrée sur l'axe, et une surface intérieure opposée à la surface exposée. La surface exposée est adaptée de sorte qu'elle est traversée par un écoulement centrifuge d'un film mince d'un élément de phase liquide lorsque ce dernier est mis en rotation. Au moins une partie de l'élément de support est perméable ou semi-perméable ou poreuse de façon à laisser des éléments de phase liquide ou gazeuse le traverser entre les surfaces extérieure et intérieure, mais à empêcher le passage de particules d'échelle micrométrique. Le réacteur peut être utilisé pour cristalliser ou précipiter une solution tout en empêchant une inhibition graduée sur la surface extérieure; il peut aussi être utilisé dans des applications de filtration à contre courant.
