The Fluitec mixer/heat exchanger Temperature curve, shear and mixing in a mixer / heat exchanger the CSE-XR mixer / heat exchanger. It was possible to adjust the temperature profile over the cross-sectional area to 80°C +/- 1.0°C during continuous production. Even momentary temperature fluctuations of up to +/20°C upstream of the mixer / heat exchanger inlet can be compensated thanks to the exchanger’s high mixing efficiency. However, this is conditional on a heat exchanger design that takes account of various additional criteria. Detailed calculation methods exist to facilitate temperature profile...

Reactors based on mixer/heat exchangers Reactors based on mixer-heat exchangers A first-generation mixer / heat exchanger, for example, can be used to mix two highly viscous fluids. The required relative lengths, namely L/D = 12 to 20, enable a considerable quantity of heat to be simultaneously supplied and removed. More complex mixing tasks can be realised with more recent heat exchanger generations. A low-viscosity catalyst, for instance, can be added to a high-viscosity monomer using a third-generation Fluitec mixer / heat exchanger while simultaneously removing the reaction heat. Thanks to...

Typical applications Typical applications Cooling polymers in extrusion processes CSE-XR mixer / heat exchangers are used in extrusion processes to modify the temperature of the melt (adjust the viscosity) and establish optimal conditions for processing. A homogeneous, uniform cooling must be ensured when extruding foams, because there is a risk of maldistribution if the viscosity increases abruptly (clogging of the individual tubes of a multitube heat exchanger). Due to its special design, the CSE-XR mixer / heat exchanger is able to cope with any differences between the viscosity at the inlet...

Multitube heat exchangers Multitube heat exchangers with static mixers Multitube heat exchangers with mixing elements in the multitubes are ideal for product viscosities between 50 and approximately 500 mPas. Various static mixing elements can be installed in the multitubes depending on the heat transfer application. These elements increase the heat transfer from the product to the tube wall, so that smaller sizes can be realised than if the multitube heat exchanger has no mixing elements. Multitube heat exchangers are not suitable for processes where the residence time is critical or for cooling...
