Description

The Polyol Pilot Unit supports the development of advanced polyols—multi-alcohol molecules used as key polymer intermediates, especially for polyurethanes. The unit supports research on novel polyol synthesis routes incorporating reactive intermediates. It consists of several high-pressure reactors, a dedicated distillation column, and supporting subsystems. The distillation section provides purification of reactants and solvent recovery for reuse. The design minimizes stagnant zones to ensure safe and stable operation. Parallel reactors enable flexible experimentation and parallel testing campaigns. Each reactor is equipped with dual gas and dual liquid feed systems. Liquid feeds are precisely metered using HPLC pumps and mass flow measurement. Reactors operate under controlled high-pressure and temperature conditions. All process equipment is constructed from 316 stainless steel for chemical compatibility. Nitrogen inerting is used throughout the system to enhance safety. Off-gas and liquid effluents are treated via an integrated scrubber system. The unit is fully automated with PLC-based process control.
