Cutting-edge Design & Precision Manufacturing

Neorius reactor internals address the root causes of performance limitations—including Fouling, High Pressure Drop, and Thermal Maldistribution—helping refineries achieve:

Increased Product Yields: Optimizing catalyst utilization for higher recovery of valuable light ends.

Extended Cycle Life: Reducing unplanned shutdowns caused by excessive pressure buildup.

Feedstock Flexibility: Enhancing the capability to process heavier, higher-margin feeds without compromising performance.

Axial Flow Reactor Internals

In Down Flow reactors, process fluids pass vertically through the catalyst bed. We supply a complete suite of high-performance internals designed to ensure uniform distribution and maximize catalyst efficiency.

Feed Diffuser: Installed at the inlet to dissipate fluid kinetic energy and provide initial distribution, protecting the top layer of the catalyst bed.	Liquid Distributor: A critical component ensuring highly uniform liquid irrigation across the catalyst surface, essential for optimal reaction rates and product purity.	Support Grid: Fabricated from high-strength Wedge Wire and reinforced beams, engineered to withstand extreme vertical catalyst loads and operating pressure differentials.
Quench Mixing Tray: Designed for multi-bed reactors to provide rapid cooling and efficient thermal mixing of inter-bed fluids within a short vertical distance.	Outlet Collector: The final barrier at the reactor bottom, ensuring reliable catalyst retention with minimal pressure drop.	Header & Hub Lateral Systems: Specialized bottom collection systems designed to maximize flow efficiency and minimize dead volume in specific vessel configurations.

Radial Flow Reactor Internals

Radial Flow reactors demand exceptional mechanical precision and thermal stress management. Neorius specializes in low-pressure-drop, high-strength radial solutions engineered for longevity.

Centerpipe: The core flow collection device. We utilize precision slot calibration and Finite Element Analysis (FEA) to ensure structural stability under severe thermal cycles.	Scallops: Vertical modules installed against the reactor wall. Our Wedge Wire or perforated plate designs replace traditional bulky outer baskets, reducing maintenance costs and increasing usable catalyst volume.	Outer Basket: Continuous annular designs that provide maximized open area for applications requiring extremely low differential pressure across the bed.	SSR-Flow: Engineered for high-temperature refinery applications. Its unique self-supporting structure accommodates thermal expansion freely without contacting the reactor wall, significantly reducing the risk of mechanical failure due to thermal stress.
