Abrégé
(EN)
A static mixer having one or more stages and/or elements. The static mixer may be scaled from bench size to any commercially desired size. During scale-up the surface area to void volume ratio is maintained constant. Maintaining this ratio constant may be accomplished by increasing the number of bars in each element of the static mixer.

(FR)
L'invention concerne un mélangeur statique comprenant un ou plusieurs étages et/ou éléments. Ce mélangeur statique peut être adapté entre une taille de laboratoire et n'importe quelle taille industrielle souhaitée. Pendant une mise à niveau, le rapport entre la zone de surface et le volume vide est maintenu à un niveau constant. Le maintien de ce rapport à un niveau constant peut s'effectuer par augmentation du nombre de barres dans chaque élément dudit mélangeur statique.
