Fuel Oils is a group of dense and high viscosity oil products. Generally, fuel oils are categorised based on their boiling points and viscosity. They are typically used for power generation, heating, and in marine engines. In our definition, Fuel Oils include:

Fuel oil that has been under the cracking process. Cracking is a refining technique where large hydrocarbon molecules are broken down into smaller, more valuable products. This process is essential for producing lighter and more valuable fuels from heavier crude oil or other hydrocarbon sources. Based on its sulphur content it can be either High Sulphur Fuel Oil (HSFO) with a sulphur content higher of 1%, Low Sulphur Fuel Oil (LSFO) with a sulphur content lower than 1% but higher than 0.5%, or Very Low Sulphur Fuel Oil (VLSFO) with a sulphur content lower than 0.5%.

"Straight run fuel oil" refers to a type of fuel oil that is obtained directly from primary refining operations without undergoing additional treatment, such as cracking or other secondary processes. The term "straight run" indicates that the fuel oil is produced by the initial distillation of crude oil in the CDU. This stream is then used as feedstock for further processing to secondary units, producing lighter products.

VGO stands for Vacuum Gas Oil. It is a type of intermediate product obtained during the refining of crude oil. Specifically, after the atmospheric residues from the CDU are being processed by the Vacuum Distillation Unit (VDU), the biggest share of VDU’s output is VGO (which can be either high or low sulphur, based on the crude feedstock).

Similar to the above, the residues from the VDU are the feedstock for the Coker, a refining unit. A large part of the Coker’s output is the Coker Gas Oil (light or heavy) which is then used in further processing from the refinery, usually through the fluid catalytic (FCC) or hydrocracking (HCU) units.

A type of fuel oil that is heavier than regular diesel fuel. It is a distillate product derived from crude oil during the refining process. Heavy gas oil is commonly used as a fuel in various applications, including industrial processes, power generation, and marine engines

Slurry Oil is a lower viscosity, catalytic cracked clarified oil manufactured to meet the viscosity specifications desired. It’s often used in blending of residual fuel oil to achieve the required viscosity.

A mixture of C12 and higher components including naphthalene, methyl-indenes, anthracene, fluorene and other polyaromatic components. It originates from high temperature cracking of petroleum fractions. CBFS is used to produce carbon black, a widely-used reinforcing agent in the rubber and tire industry.

Cutter stocks are oil and oil-related (by)products used to thin oil. They are typically used to reduce viscosity to produce on-spec fuel oils. But they can also be blended to reduce sulphur content and produce low sulphur fuel oils.
