IPT Srl’s HPPO process for the production of Propylene Oxide (PO) is developed based on a slurry-phase reaction in a Continuous Stirred Tank Reactor (CSTR).
This technology stands out from conventional HPPO (Hydrogen Peroxide to Propylene Oxide) processes that typically rely on fixed-bed reactors. Our approach not only optimizes performance but also reduces operational and capital costs, offering a compelling alternative for PO production facilities worldwide.
🔹 Higher Yields — More Product, Less Waste Our process consistently achieves an overall PO yield of around 94%, compared to ~92% in typical fixed-bed HPPO systems. That’s not just a percentage point — it’s a measurable gain in efficiency and profitability
🔹 Better Heat Control = Safer, More Stable Operation Thanks to the natural mixing in a slurry reactor, heat is evenly distributed throughout the system. That means no hotspots, uniform temperature profile, better control of exothermic reaction, and more consistent product quality.
🔹 Stronger Reactivity and Faster Reactions In a fixed bed, the reactants have to find their way through a dense catalyst structure. In our slurry setup, everything is already well mixed in a homogeneous mode. The result? Faster reactions, better mass transfer and contact, and higher selectivity.
🔹 Lower Capital Cost The IPT slurry technology uses standard equipment, even in the reaction section. This means a lower capital investment compared to fixed-bed systems that require custom high-pressure tubular reactors. That’s a major plus for companies looking to scale quickly or build flexibly.
🔹 More Flexibility in Production Our process is more adaptable to varying production capacities, and different capacities can be designed by modular expansion strategies.
🔹 Ease of Maintenance Our slurry system with external filtration offer better accessibility for catalyst recovery, replacement, and filtration maintenance, unlike fixed-bed reactors where shutdowns is very complex and costly.
Why It Matters
