VRV supplies all main pressure vessel components for the Axens octanizing process, used to produce high-octane gasoline and hydrogen. These are:

• Octanizer Reactor
• Regenerator
• Catalyst Hoppers
• Surge Drum
• Reduction Chamber
• Lift Pots
• Washing Drum

The Octanizer Reactor has a side-by-side arrangement different from the UOP stacked design, with internals consisting of an inner and outer VEE screens. Inside the reactor, the feedstock charge flows radially across the annular catalyst beds, while the catalyst flows vertically downwards by gravity.

The Regenerator has a two-bed stacked construction with flow arrangement similar to the one of the Octanizer. Typical construction materials are 321 SS and Incoloy 825.

VRV also designs and manufactures the complete set of external pressure vessels for the charge and discharge of the catalyst at the top and the bottom of the Octanizer / Regenerator Reactors. These components are: Catalyst Hoppers, Surge Drum, Reduction Chamber and Lift Pots.

The Washing Drum has the purpose to neutralize burning effluent and comes in contact with highly corrosive products and it requires an internal special lining in Fiber Reinforced Plastic (FRP) CCR Components (AXENS process).
