Key factor to maximize profitability:
Hyvahl™ on-stream factor
Reliable operation thanks to Axens’ Patented PRS™ Technology

By-Passable Reactors
1st Reactor bypassed if dP increases
Not possible to add catalyst to the system
Minimum CapEx option
PRS1R: Re-Loadable Reactors
1st reactor can be bypassed and reloaded
while unit in operation
Good protection from metals/dP issues
Compromise between cost and cycle gain
PRS2R: Permutable Reactor System
2 first reactors can permutate in lead/lag
Well suited for high metal content
Complete protection from metals/dP issues

CCR < 3 wt% > 3 wt%
Metals < 5 wtppm 20-25 wtppm
Poor vaporization
High coke production
High Regenerator Temp.
High metal content
Poor Yields
Coke deposit Rx & Ovhd
Poor Yields
Catalyst deactivation
Mechanical reliability issues
Detrimental catalyst effect

2020 Bunker Fuels: A Way to Boost Profits
Take advantage of the 2020 market: Bunker fuel production
coupled with secure high-value products
Bunker Fuel production should
be a means to maximizing profit,
not a primary objective
High-value products from
conversion/refining should
remain the focus of refiners
