Description

The Stirred Dry Phase Polymerization Unit developed by Vinci Technologies is a bench-scale chemical pilot plant designed to study polyolefin polymerization under industrially representative conditions. It simulates fluidized-bed processes in a compact stirred reactor configuration. The unit is used for catalyst screening, kinetic studies, and copolymerization development for polyethylene and polypropylene grades. A low-speed ribbon-type agitator ensures homogeneous solid mixing and efficient gas–solid contact while preserving particle morphology. The jacketed reactor design provides precise temperature control to manage highly exothermic polymerization reactions. Optimized gas distribution at the reactor bottom ensures uniform bed fluidization. Monomer, comonomer, and hydrogen ratios are accurately controlled to reproduce industrial operating conditions. Real-time gas analysis and advanced automation enable stable, reproducible operation. The unit delivers reliable performance and scale-up data for polymer process development.
