Wall-sheeting limits productivity. It disrupts throughput, hampers heat transfer, and drives up downtime in polymerisation. CASAFA takes this challenge head-on. Using a blend of high-fidelity simulations and smart experimental design, we investigate the core mechanisms behind fouling in fluidised bed reactors. We target the influence of heat, triboelectrification, and particle dynamics — to drive practical anti-fouling innovation.
Understanding the problem starts with seeing the details
Fouling in polymerisation plants is not just a nuisance. It’s a complex, layered phenomenon. In CASAFA, we dig deep into its origins. We study particle softening under thermal stress and the effects of static charging (triboelectrification). By isolating and quantifying these mechanisms, we gain clarity on how they alter reactor performance and when they trigger wall-sheeting.
Pairing lab work with machine learning for sharper insights
To decode the full fingerprint of polyolefin mixtures, we combine experimental set-ups with deep-learning-powered GPC-IR analysis. This hybrid method allows us to identify early fouling signals, predict behaviour under different conditions and test the real-world effectiveness of anti-fouling additives. Simulations complement our tests by modelling flow, heat and particle behaviour in real time.
Better data, better decisions. Fewer shutdowns
Every unnecessary shutdown costs time, energy, and money. CASAFA enables more confident decision-making by equipping engineers with science-backed, data-driven tools. Rather than reacting to fouling, operators will be able to anticipate and prevent it, optimising both process stability and production flexibility.
