Pachem-HHO_30A
Additive for Heavy Heating Oils
General Information:
Pachem-HHO_30A is a multifunctional additive package for Heavy Heating Oils designed to improve fuel economy and boiler/furnace system cleanliness and to reduce corrosion caused by vanadium and sulphur present in the oil. Due to specially selected constituents, Pachem-HHO_30A provides the following functionalities:
• detergency,
• vanadium and sulphur anticorrosion,
• improved combustion process
Presence of very active Iron and Magnesium containing components provides additional protection against high-temperature corrosion and effectively improves burning process. The package not only improves the combustion of heavy fuel oil, but also improves the combustion of biomass, coal, coke and petroleum coke. Pachem-HHO_30A is a liquid from amber to brown colour and remains stable in the wide scope of temperatures.
Typical Physical and Chemical Properties:
| Parameter | Unit | Value | Test method |
|---|---|---|---|
| Colour, at 20 ºC | - | Amber to brown | PB-01 - Edition 1 |
| Density at 15 ºC | kg/m3 | 850 - 950 | PN-EN ISO 12185:2002 |
| Pour Point | ºC | < -20 | PN-EN ISO 3016:2005 |
| Flash Point | ºC | > 35 | PN-EN ISO 2719:2016 |
| Viscosity at 40 ºC | mm2/s | < 4 | PN-EN ISO 3104:2004 |
Application:
One way to prevent boiler system damage, caused by high- temperature and low-temperature Vanadium corrosion, is the addition of substances (based on the magnesium compounds) by modifying the properties of the fuel. Also, iron and calcium supplements interacting with magnesium improve combustion and reduce excess air. The advantages of using the additive composition comprising iron and magnesium compounds are as follows:
• Increase of the melting point of sodium and vanadium salts preventing from corrosion and formation of sludge,
• Increase of brittleness and fragility of existing deposits, what makes their removal easier
• Reduction of sulfur trioxide - SO3,
• Lowering of the dew point due to sulfuric acid reduction,
Better flow of heat through the boiler superheater tubes due to clean surfaces provided by the additive
• Prevention or evident reduction of corrosion,
• Reduction of the boiler operating costs,
• Reduction of emissions of smoke and deposits
Treat rate:
Typical dosage of Pachem-HHO_30A is 800-1200 ppm m/m. Suggested treat rate is 1000 ppm m/m. The treat rate should be adjusted to base oil quality (mainly vanadium and sulphur content) and client’s requirements for performance and corrosion limits.
Packaging:
Pachem-HHO_30A is available in bulk, 200 l barrels, or 1000-litre tanks (IBC). Other types of packaging are available on request.
