Qenos Case Study: Aspen Polymers for HDPE Batch Process Optimization
Qenos used Aspen Polymers to model HDPE batch reactions, cut plant trials, and reduce off-spec material in new product development.
Qenos, an Australian HDPE producer, modeled batch reactor kinetics with Aspen Polymers using plant historian data and molecular weight distributions. The model predicted final polymer properties, pressure profiles, and reactant concentrations, enabling optimized feed strategies. Results included six months faster development cycles and $135,000 annual savings from lower co-monomer use and reduced wax byproduct.
Aspen Polymers model predicted molecular weight, pressure, and phase concentrations in HDPE batch reactors
Gradual co-monomer addition reduced usage and saved $60,000 per year
Gradual hydrogen addition cut wax byproduct, saving $75,000 per year
New product trials completed six months ahead of schedule with three-batch validation
Batch process modeling replaced trial-and-error recipe development for custom grades
