Devolatilization Technology

DSXL devolatilization technology improves product quality and reduces cost.

Devolatilization Technology Introduction

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.

Technical Principle Of Devolatilization Technology

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.

Technical Advantages Of Devolatilization


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
