HSFO 180 (High Sulfur Fuel Oil 180 cSt) is a residual fuel oil widely used in the marine, power generation, and industrial sectors. It is characterized by its high viscosity (180 centistokes at 50°C), high sulfur content, and excellent calorific value, making it a cost-effective energy source for large-scale operations. Produced through the vacuum distillation of crude oil and blending of heavy fractions, HSFO 180 plays a critical role in bunker fuel supply and heavy industrial applications.
Typical properties include:
| Specification | Value |
|---|---|
| Kinematic Viscosity at 50°C | ~180 cSt |
| Density at 15°C | 0.95 – 1.01 kg/L |
| Sulfur Content | 2.5 – 4.5 wt.% (high sulfur grade) |
| Flash Point (COC) | ≥ 60 °C |
| Pour Point | up to 30 °C (varies with origin) |
| Water Content | ≤ 1.0 wt.% |
| Ash Content | ≤ 0.1 wt.% |
| Vanadium and Nickel Content | Relatively high, requiring treatment in some combustion systems |
| Calorific Value | ~40 MJ/kg |
These specifications may vary slightly depending on refinery source and blending requirements.
• High energy density, delivering consistent combustion performance.
• Cost-effective fuel compared to distillates such as diesel or MGO.
• Widely available in global markets as a primary bunker fuel.
• High sulfur content, requiring compliance with IMO 2020 emission regulations (scrubbers or blending with LSFO).
• Robust performance for large-scale power and industrial boilers.
• Marine industry: Used as bunker fuel for ships with scrubber systems.
• Power generation: Fuel for thermal power plants in regions where HSFO is permitted.
• Industrial applications: Boilers, furnaces, and kilns requiring high calorific fuels.
• Blending stock: For producing low-sulfur fuel oils (LSFO) or intermediate fuel oils (IFO).
HSFO 180 is supplied in:
• Bulk shipments via marine tankers
• Onshore storage terminals
• Pipeline systems to ports and refineries
• Barges and bunker supply vessels for direct delivery to ships
• Store in heated storage tanks to maintain fluidity.
• Avoid direct exposure to open flames.
• Use PPE (gloves, goggles, protective clothing) during handling.
• Ensure preheating before pumping or combustion (typically 40–60°C).
• Follow IMO, MARPOL, and ISO 8217 standards for safe handling and transport
