Hydrocracking valve applications
Hydrogen-rich processing and catalyst handling place containment and the complete operating envelope at the centre of selection.
The application
Ebullated-bed hydrocracking combines heavy feedstock, hydrogen and suspended catalyst. Catalyst handling introduces solids-related challenges alongside pressure and temperature. Isolation requirements must be evaluated for the actual process location and operating sequence.
What makes the duty demanding
- Hydrogen containment and external leakage
- Wear associated with catalyst particles
- Sealing under changing process conditions
Selection focus
Define process compatibility, particle exposure and test requirements before discussing a valve configuration. The application name is not a material specification.
