CSE-XR
®
Reactor
By combining static mixing elements with shell-and-tube heat exchangers manufacturer, basic operations suchas mixing, heat and mass transfer for chemical reactions are now possible even for highly viscous
liquids. The excellent heat transfer performance and the high mixing efficiency of the CSE-XR
® al-lows delicate operations also in laminar flow.
The new CSE-XR Mixer / Heat Exchanger or Re-
actor opens cost-saving opportunities in the field
of chemical reactions and polymerization proces-
ses. Using specially designed static mixing elements
(Fig. 1), a strongly defined cross sectional mixing
behavior and a high surface renewal rate are achie-
ved, making the CSE-XR suitable for strong exo-
and endothermic chemical reactions. Temperatu-
re control and equilibration is achieved exactly and
completely at all flow conditions.
Fig. 1: The new CSE-XR Mixer / Heat Exchanger CSE-XR: the next generation energy transfer, marking the equipment more ex-
pensive in investment and operation costs. This
problem can be solved by inserting additional
heat exchanger tubes into the existing device. Thereby
the new, inner tubes pierce the static mixing ele-
ments and benefit in the same way from the mixing
efficiency as the outer, converntional tube. The ad-
ditionally created surface area and the achieved
high Nusselt-number in the CSE-XR create a re-
markable high heat transfer in relation to its volu-
me. Fig. 2 shows the performance of CSE-XR in
relation to traditional apparatuses and its superio-
rity especially in large-scale plants. Aperfect combination The very high mixing efficiency is characteristic for
conventional CSE-X mixing elements in general.
By increasing the tubes diameter, however, the
CSE-X elements reach its limit for the use in mo-
notube heat exchanger. In diameters greater than
DN 80, the heat transfer coefficient
