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
