mikromakro®-mixing means the systematic use of static mixers of different geometries and sizes. Basically, a rough but well distributed pre-homogenisation is achieved in the makro-mixer, while a perfect homogenisation is realised in the following mikro-mixer. Fluitec CSE-X® mixers are well established and proved for industrial mixing processes of highest demands. Standard CSE-X® mixers consist out of 4 to 12 bars. The final design, the arrangement and the sizes of mikromakro®
mixing elements, however, are customized to its individual application.

The fillers for reaction columns where, usually at higher temperatures, take their course reactions of absorption, desorption, extraction, and suchlike, are manufactured in standard forms (Raschig rings, Pall rings, Berl saddles) and dimensions, as well as on customers’ request.
The ceramic fillers are manufactured of chemically resistant quartz porcelain.

In all Kenics® KM Series Static Mixers, a patented helical mixing element directs the flow of material radially toward the pipe walls and back to the center. Additional velocity reversal and flow division results from combining alternating right- and left-hand elements, thus increasing mixing efficiency. All material is continuously and completely mixed, eliminating radial gradients in temperature, velocity and material composition.

Our standard, pre-engineered thermoprofiler® static mixers provide cost-efficient mixing of two least fluid streams. Our custom designed blendrex® mixing elements continuously split the delivered flow, remix it, homogenize it, and symmetrically set the melt’s temperature gradients to assure even mixing, uniform additive dispersion, and temperature profile consistency.

The concept behind a static mixer is simple: fluid flowing through a pipe is channeled through a geometric arrangement of mixing elements. The element geometry within the housing causes the flow to divide, mix, divide again and mix again until complete. The flow then continues in a pipe as if it had gone through conventional batch mixing in tanks, with the distinct difference that the degree of homogeneity can be precisely controlled within the sanitary static blender.

Two basic-No Moving Parts- Motionless Mixer designs are offered for use in turbulent and laminar flow mixing applications.
The elements are made of two inclined semi-elliptical plates opposite to each other. The mixing operation is based on the splitting and diverting of input streams. In turbulent flow applications, the elements enhance the random dispersion of substreams so that a unit with six elements is sufficient for most applications.

Static mixers are well established and widespread in all fields of chemical process technology. It is characteristically for static mixers, that, in contrast to dynamic mixers, only the media to be mixed are in motion. The liquids or gases are mixed by pump energy only, while the geometrically strong defined Fluitec mixing elements in the tube remain in position.

The mixer/heat-exchanger CSE-XR was developed and patented by Fluitec AG. It is the most important invention in the static mixing technology of the last 20 years.
The CSE-XR is mainly used for temperature conditioning of highly viscous liquids at laminar flow. A strongly defined and well controlled homogeneity is guaranteed in any situation as well, as a very narrow residence time distribution. The reason for this excellent performance is its geometry, which is consequently based on the geometry of the most efficient static mixer type, the CES-X.
The very high radial mixing efficiency constantly ensures an intensive flow against the internal heat transferring tubes, thus allowing a
the compact design of this device.
Multitube heat exchangers are often not dedicated for scale-ups. Problems occur mainly in cooling processes at laminar flow conditions, when the product can "freeze" in particular tubes, due to its increased viscosity at lower temperatures. Uncontrolled residence time distribution and maldistribution are thereby leading to a bad process control.
Monotube heat exchangers (tubes with a double shell) can be built much smaller, if using static mixers. The mixing elements are improving the surface renewal rate significantly.

Static mixers are well established and widespread in all fields of chemical process technology. It is characteristically for static mixers, that, in contrast to dynamic mixers, only the media to be mixed are in motion. The liquids or gases are mixed by pump energy only, while the geometrically strong defined Fluitec mixing elements in the tube remain in position.
Among others, static mixing elements can be applied in the following fields of application:
mixing of pumpable fluids
dispersing and emulsifying of insoluble liquids (cleavage)
mixing of reactive liquids
mixing and homogenisation of polymers (hot-melts)
contacting of gas and liquid phases
mixing of gases
tempering of viscous media
In contrast to empty tubes, static mixer possess a very high efficiency for self-cleaning.
Wear of static mixers is negligible due to the lack of any moving parts.

FLEXIPAC® and GEMPAK® structured packings provide high capacity, higher efficiency and lower pressure drop than any random packing and most trays available today. Revamping existing packed or trayed columns with structured packing from Koch-Glitsch will increase the operation capacity of the tower, lower the pressure drop, and lower the energy cost of the distillation or absorption operation. Our structured packing elements may be fabricated in a variety of metals and plastics, as well as in ceramic.

Metex OPTI-PACK™ knitted wire mesh Structured Tower Packing is designed to overcome many of the shortcomings of other devices. The packing consists of multiple strands of very fine wire, typically 0.00045" diameter, knitted together to form a 2-ply layer of flat mesh. The flat mesh is corrugated, or "crimped" to give it a uniform, 3-dimensional structure of "peaks and valleys." These peaks and valleys provide a path through which vapor can readily flow, both radially and axially.
The multistrand fine wire generates high surface area (typically 500 ft2 to 800 ft2 per ft3) and a "capillary effect" on the descending liquids to promote good liquid distribution, residence time and thin-film development.
The resiliency of the fine wire that ensures that the packing will conform to vessel anomalies between the wall and the internals. These gaps often lead lead to vapor bypassing that keeps your unit from realizing its design performance.
These mechanisms work together to promote the intimate liquid-vapor contacting needed to achieve the separation demanded by high-value-added processing. Typically, structured sire mesh tower packing exhibits Height per Equivalent Theoretical Plate (HETP) in the range of 3 to 12 inches, depending on the application of fluids. In general, these packings offer the highest efficiency per foot of bed and the lowest pressure drop per theoretical stage, versus other mass transfer devices.
