Hydrocracking valve applications

Hydrogen-rich processing and catalyst handling place containment and the complete operating envelope at the centre of selection.

Hydrogen · Pressure · Solids

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.
