Reactor Internals
Shell reactor internals technology uniformly distributes liquid and gas, minimises thermal maldistribution, and maximises catalyst volume and utilisation to enable improved performance and safety.
Could the latest-generation reactor internals unlock additional value for you?
Shell reactor internals technology enables increased active catalyst volume to be loaded and can significantly improve the performance of your reactor.
If your reactor is showing signs of fouling, high-pressure drop or thermal maldistribution, new reactor internals could help. In addition, reactor internals can help you increase the severity of your feeds, increase yields and capture more value.

Learn more about Shell reactor internals
Shell enable increased active catalyst volume to be loaded and almost 100% of the catalyst particles to be used. Combined with near-perfect vapour-liquid distribution and elimination of radial maldistribution, they can significantly improve the performance of the reactor.
Shell reactor internals can help you:
- Increase throughput capacity
- Meet tighter product specifications
- Eliminate pressure drop problems
- Achieve shorter turnaround times and more days on stream
- Improve return on investment in reactors and catalyst systems
Typical performance improvements are increased cycle length, the ability to process more severe feeds, and increased product yields or improved product properties. Additionally, they enable shorter turn-around time and can increase process safety. Shell reactor internals are critical for applications with more stringent product specifications, such as ultra-low-sulphur diesel production (ULSD), high-margin applications such as hydrocrackers, as well as for the safety and reliability in high reactive feed applications such as C4/C5 and Pygas hydrogenation in petrochemical plants.
Shell filter trays reduce pressure drop build-up and maximise unit run length. Advanced fouling abatement technologies are of utmost importance as the refining industry is processing increasingly difficult feedstocks.
The use of pressurised testing facilities and advanced computer simulations has led to continuous improvements for Shell reactor internals.
- Minimised pressure drop
- No distributive packing required
- Small space requirement, which enables more space for active catalyst
- Higher tolerance to tray tilt, which offers a robust performance over wide operating window
- Bolt-less, weld-less and ergonomic design that facilitates quick installation, easy maintenance and a minimised turn-a-round time.
