Based on the characteristics of polymer and the rich application experience of static mixer and high-efficiency heat exchanger, Dodgen has designed single-stage or multi-stage devolatilization process. Its core equipment including heat exchanger with mixing elements, blender and high efficiency distributor, to achieve the ultimate goal of improving product quality and reducing operation costs.
The underlying principle behind Dodgen DSXL devolatilization involves the rapid and even heating of the polymer to a certain temperature, and/or the addition of additives that help the volatiles escape, and then the polymer disperse evenly in the separation tank, the volatiles are released from the polymer matrix as a result.
The Polymer degradation is reduced to avoid the destruction of polymer form due to high shear stress
High-efficiency heat exchanger avoids high-temperature gradients and localized high temperature effects
Low residue content and low operation cost
No moving parts, low energy consumption
Decreasing in maintenance costs
