Usually all Heavy Fuel Oils (HFO) when contaminated with water form stable water in oil emulsions (W/O emulsions). The formation of these emulsions is due to asphaltenes, resins and other heavy hydrocarbon molecules of HFO acting as ‘natural emulsifiers’. These emulsions are very stable and are difficult to be broken without the application of special formulated products which called de-emulsifiers.
In marine fuel handling systems the presence of Water in Oil emulsion could lead to the formation of sludge that can be deposited and encrusted inside the metallic tubes. These conditions can block the filters and prevent the separation of metallic elements/ash which the HFO contains. They can also boost the biological growth and increase microbes with result of fuel degradation and decrease in the combustion efficiency.
When HFO is contaminated with seawater can cause serious damage on metallic parts during handling. This will lead to the formation of corrosive substances at the exhaust.
In any case the quantity of water must be removed before burning.
Advantages and Characteristics
- Breaks Water in Oil emulsion and separates most of the water in settling tank and in the centrifuge.
- Improves the efficiency of separator.
- Prevents formation of sludge in the tubes and the blockage of filters.
- Facilitates the removal of metallic elements.
- Improves fuel’s flow by reducing viscosity without affecting other physical characteristics.
- It is not toxic, not corrosive and it does not contain chlorinated solvents.
- Suggested for use especially with marine fuel types IFO 180, IFO 380 and bunker C when having high water and ash/metallic content.

APPLICATION AND USE
The product should be applied inside the fuel storage tank or by a dosimetric pump at the initial stage of fuel handling, so as to ensure good dispersion of the active ingredients. The separation of water will be succeeded both inside the settling tank and in the fuel centrifuges at a temperature 60-70°C. The separation will be slower in the settling tank, where the water will be accumulated at the bottom of the tank and must be collected and faster when the fuel centrifuges.
The dosage should be according the following table, taking into consideration the volume percentage (%) of water as recorded in the fuel analysis.
| Liters of product/liters of HFO | 1/5000 | 1/2500 | 1/1250 | 1/500 |
|---|---|---|---|---|
| Volume percentage (%) of water | 0.5-1.0% | 1.0-2.0% | 2.0-3.0% | 3.0-5.0% |
If no fuel chemical analysis is available, then Marichem Water in Oil test kit (Order Number: 720101) can be used for measuring the volume percentage (%) of water in fuel oil.
Safety and Handling
| HANDLING | Handle with care. Store in a dry, cool and well ventilated environment. |
|---|---|
| SAFETY | IMMEDIATE ACTIONS |
| Eye Contact | Avoid Eye contact. Otherwise, flush with plenty of water for a few minutes. Seek medical attention. |
| Skin Contact | Avoid Skin contact. Otherwise, wash contaminated area thoroughly with water. Seek medical attention. |
| Inhalation | Avoid inhalation of vapors. Otherwise, seek fresh air source at once. Seek medical attention. |
| If Swallowed | Avoid ingestion. Otherwise, consume a considerable quantity of water. Do not induce vomiting. Seek medical attention. |
| GENERAL INSTRUCTIONS | Avoid spillage, splashing and mishandling. Precautionary measures for body protection are strongly recommended before use. |
