Designs OF Static Mixer

Chemical reactions can be carried out in plug flow and loop reactors with static mixing devices under
finely controlled conditions, which is especially crucial for extremely exothermic and endothermic
processes. In addition to quickly mixing and/or dispersing feed components, S-Cube mixers create
plug flow and significantly increase heat transfer both within the fluid and with contacting surfaces
for temperature control.
Dispersions are generated when the relevant components are immiscible and a liquid component
forms the continuous phase. To create the proper mean, drop size and narrow drop size distribution,
uniform energy dissipation in the total mixer volume and simultaneous distribution of the
components over the full pipe cross-section are used.
A wide variety of firms have developed static mixers over the years, all based on the notion of
circulating streams radially via a set of metal baffles. Metal twists, corrugated sheets, parallel bars,
small-diameter channels, or tabs protruding from the wall are examples of baffles. Depending on the
design, these are essentially connected flow devices with a limited amount of back mixing.
The way you need your materials distributed is a key component in deciding which s mixer is right
for you. Based on the pressure limitation of the nozzle, the allowable back-pressure/retained
volume, and the expected, or desired flow rate, the materials you’re utilizing will assist you to decide
your mixer.
The best static mixer is one that provides the desired mixing quality at the lowest pressure drop, at
the lowest installed cost, and in the smallest amount of area. Testing the mixing capabilities of each
of the numerous types available with the actual materials to be processed would be ideal. In
practice, however, this is not achievable. Relying on advice and information from several mixer
vendors is required.
Because static mixers rely on external pumps to transfer product across the mixer parts, the
pressure drop is frequently used to determine which static mixer is best. In many circumstances, the
kind and number of mixer elements are chosen to achieve the best possible mixing while staying
within a pressure drop limit.

they’re connected flow devices with a tiny amount of back mixing, depending on the design.
For more than a decade, the S-Cubes SCM-MX mixer has been the industry standard in static mixing
applications. It is made up of a grid of inclined bars in a variety of sizes. This design divides the
ingredients to be blended into layers and distributes them across the pipe’s full cross-section.
Corrugated plates produce open, crossing channels in which flow is separated into multiple sub
streams in the SCM-MV mixer. These mixers are most commonly utilized in transitional and
turbulent flow regimes to increase mass transfer between immiscible liquids. Gas mixing
applications are the best fit for these mixers.
