How to Buy Virgin Fuel Oil D6 in Developing Countries

Virgin Fuel Oil D6

D6 Virgin Fuel Oil, also known as Residual Fuel Oil, is a high-viscosity fuel used for various purposes. One essential fact to note is that it requires pre-heating to a temperature range of 104 ºC to 127 ºC (220 ºF – 260 ºF) before use. In this article, we’ll break down what D6 Virgin Fuel Oil is, its uses, and important considerations for those in need of this specialized fuel.

Understanding Fuel Oil

Fuel oil is a broad term encompassing any liquid fuel used for heating, power generation in engines, or other industrial processes. However, it doesn’t typically include lighter oils with a lower flash point or those used in cotton- or wool-wick burners. In a stricter sense, fuel oil refers to the heaviest commercial fuels derived from crude oil, distinct from lighter products like gasoline and naphtha.

Composition of Fuel Oil

Fuel oil consists of long-chain hydrocarbons, including alkanes, cycloalkanes, and aromatics. During the refining process, smaller, more volatile molecules like propane, naphtha, and gasoline are separated out, leaving behind heavier products like diesel fuel, lubricating oil, and bunker oil.

Bunker oil, often considered the bottom of the barrel, is the densest form of fuel oil. The only components denser than bunker fuel are carbon black feedstock and bituminous residue (asphalt), used for road paving and roofing.

Common Uses of D6 Virgin Fuel Oil

D6 Virgin Fuel Oil primarily finds application in power generation. It is commonly used in generators in various industries. However, recent changes in fuel quality regulations have led to the need for further refining of D6 to reduce sulfur content. This refinement process increases the cost of D6 Virgin Fuel Oil.

One critical aspect to note is that D6 Virgin Fuel Oil’s high viscosity and sulfur content make it unsuitable for small-scale applications like cars, boats, or small ships. It requires pre-heating before use, making it more practical for large ships and power plants.

Regional Variations

It’s essential to be aware that terminology can vary depending on your location. In the USA, D6 Virgin Fuel Oil goes by this name. However, in other parts of the world, it may have different designations.

Fuel oils are classified using various parameters, including viscosity, sulfur content, and ignition quality. The two key indexes used for classification are CCAI (Calculated Carbon Aromaticity Index) and CII (Carbon Insolubility Index). These indexes help describe the ignition quality of residual fuel oil, which is especially relevant in marine applications.

D6 fuel viscosity 

The viscosity of D6 fuel is typically measured in Centistokes (cSt). Common classifications include:

  • IFO 380: Intermediate D6 Fuel Oil with a Maximum Viscosity of 380 Centistokes.
  • IFO 180: Intermediate D6 Fuel Oil with a Maximum Viscosity of 180 Centistokes.
  • LS 380: Low-Sulphur (<1.5%) Intermediate D6 Fuel Oil with a Maximum Viscosity of 380 Centistokes.
  • LS 180: Low-Sulphur (<1.5%) Intermediate D6 Fuel Oil with a Maximum Viscosity of 180 Centistokes.
  • MDO: Marine Diesel Oil.
  • MGO: Marine Gasoil.

The Russian Perspective

Russia is a significant producer of D6 Fuel Oil, and its main refineries produce substantial quantities of this product. Russian D6 Virgin Fuel Oil is known for its quality and is supplied to customers worldwide.
