2016 Decision by International

Maritime Organization (IMO): global

switch in 2020 to 0.5 % Sulfur (from

currently 3.5 % High Sulfur Fuel Oil

(HSFO))

ECA’s (Emission Controlled Areas):

S specification remains at 0.1 %

In 2020, demand for HSFO will

strongly decrease worldwide

An Ebullated Bed Technology:

• Upflow Reactor, Recycle of Rx Liquid to ebullated catalyst bed

• Low and constant ΔP over the catalyst bed,

• Nearly isothermal

• Optimization Module from Axens used to control catalyst bed

expansion

• High performance internals

Axens has developed H-Oil® process based on:

On-line daily Addition/Withdrawal of catalyst:

• Constant catalyst activity, whatever metal content in the feed.

• Constant product quality

• No Cycle length

• Fully automated system

Understanding Effluent Stability-conversion limits

Asphaltenes are:

the heaviest structures difficult to characterize difficult to convert potentially unstable

Saturates / Aromatics / Resins /

Asphaltenes

MATRIX

0% 28% 48% 56% 74% 85%

Stability is the limiting factor due

to Asphaltenes condensation

When destabilized, Asphaltenes floculate and cause:

- Fouling & downtime for cleaning

- Sediment in products

VR SARA is Crude Specific
