The Outlet Collector is an essential reactor internal used to reliably collect discharged fluid from the catalyst bed to the outlet nozzle. Designed for high-severity hydroprocessing applications including hydrotreating, hydrocracking, gas sweetening, and hydrogenation, it ensures uniform flow extraction with minimal pressure drop while retaining catalyst and preventing downstream fouling.
✔ Uniform Flow Distribution
The collector draws fluid evenly across the reactor cross-section, reducing hydraulic maldistribution and improving catalyst utilization throughout the run.
✔ Low Pressure Drop Design
High open area wedge wire configuration minimizes pressure drop buildup, contributing to stable operation and longer run cycles.
✔ Catalyst Retention & Protection
Precision machined screen geometry prevents catalyst migration and fines carryover, protecting downstream piping and equipment.
✔ Robust Mechanical Construction
Designed to withstand catalyst bed loads, thermal cycling, and high pressure environments typical of refinery and petrochemical service.
✔ Flexible Design Variants
Available in cylindrical, conical, or hemispherical styles depending on vessel geometry, service conditions, and installation constraints.
In downflow reactors, the outlet collector sits at the bottom of the vessel, either within an inert bed or beneath the catalyst support grid. It captures the product flow from the catalyst bed and routes it smoothly to the outlet nozzle, ensuring even flow extraction and minimizing localized pressure spikes. In upflow or regeneration conditions, it provides reverse flow capability while maintaining catalyst retention.
Manufactured from high-performance materials selected for corrosion resistance and mechanical strength, including:
Materials are chosen to match operating pressure, temperature, and fluid chemistry for long service life.
