Impact of the Viscous Behavior of Polymers in the Design of Polycondensation Reactors

摘要

1. Trials showed that the power draw was significantly less than expected - DHR is a good technology for polycondensation 2. Cross-verification with pilot trials on known products confirmed the power draw over-evaluation 3. The reliability of rheological measurements for new grade was questioned => Process rheology should be used whenever possible 4. Higher agitator speeds help reduce polycondensation time up to 40% 5. A new double helical ribbon impeller was proposed for reactor retrofitting.
