Abstract
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.
Claims14
A static mixer having a predetermined number of elements and predetermined number of discrete bars in each element, said static mixer having a total cross sectional area of at least 300 sq mm and satisfying the inequality Y>26.0X{circumflex over ( )}−0.54, wherein Y is the active surface area to void volume ratio in 1/mm and X is the total cross sectional area in square mm of said static mixer.
A static mixer having a predetermined number of elements and predetermined number of discrete bars in each element, each element having a predetermined cross sectional area, said cross sectional area of at least one element being greater than 300 sq mm, said static mixer further comprising an active surface area, void volume and perimeter, said perimeter having a predetermined size and shape, said active surface area and said void volume defining an active surface area to void volume ratio, said ratio being greater than 1.5.
