Low Sulfur Fuel Oil (LSFO)
EAJV technology beside on EPC services capable to design and construct Low Sulfur Fuel Oil (LSFO) Plant. Hydrodesulphurisation (HDS) is one of the processes in the refinery to reduce sulfur and convert sulfur in liquid phase into hydrogen sulfide.

Hydrodesulphurisation (HDS)

HDS is a catalytic reaction in presence of Co/Mo catalyst where heavy cyclic sulfur compounds such as theophoric sulfur compounds are cracked into H2S at high pressure/temperature with hydrogen.

With our design the sulfur specification will be reduced to 0.5 wt. % on the open seas, in controlled zones (close to city areas) it will be specified as ultralow sulfur bunker fuel (< 0.1 wt. %).
There is also a likelihood that bunker fuel (low sulfur fuel oil, LSFO) demand may be offset by switching to alternative fuels such as Marine Diesel oil (MDO) or Marine Gasoil (MGO) with lower sulfur content. The most important characteristic for IMO or bunker fuel is sulfur content; but, other constraints such as ash content (0.15 wt.%), vanadium (300 ppm), aluminum and silicon (80 ppm), and water (0.5 wt.%) are also specified.

This plant includes the following units:

• Feed and Products Storage
• Hydrogen Production and Extraction
• Gas Reformer Plant (Steam Methane Reforming / SMR)
• Pressure Swing Adsorption (PSA) H2 purification
• De-asphalting Plant – Depending on Feed Metal (Ni and Vanadium) Content
• hydrodesulphurization (HDS) Plant
• Product Fractionation
• H2S removal and conversion
• Utilities including power, steam, and waste management systems
• The economy of system depends to availability of utility, feedstock composition and product blending scenarios.
