Heavy Hydrocarbon Cut

Heavy hydrocarbons are produced by blending feedstocks with flash points above 40°C, such as solvents from the 400 series and raffinate, with industrial oils. The resulting product, typically in the C10 to C25 carbon range and composed of paraffinic, naphthenic, and aromatic functional groups, has an approximate density of 800–840 kg/m³ and is commonly known as gas oil or diesel fuel.

Production Process

The feedstocks, supplied from refineries as middle distillate fuels with boiling points ranging from 150°C to 400°C, are transported and unloaded by tanker trucks. They are then injected into the production tanks according to laboratory-formulated ratios and thoroughly blended using circulation pumps.

Finally, after comprehensive quality control, the finished product is loaded into transport tankers.

Additional Information

This process, particularly in the production of heavy paraffinic hydrocarbons, is often considered a by-product stream. Due to its low octane number, it is not suitable for use as gasoline. However, because of its long carbon chain, it plays an important role in the synthesis of detergents.

Features and Benefits

High Viscosity:Helps maintain a stable film in systems and reduces wear on components.
High Thermal Stability:Maintains its properties and resists decomposition at elevated temperatures.
Good Lubricity:Provides effective lubrication and reduces friction between surfaces.
Oxidation Resistance:Resists deterioration when exposed to air and oxygen.
Fuel Use:Although unsuitable as gasoline, it can be used as fuel in specific applications.

Applications

Detergent Production:Its long carbon chain makes it an important feedstock for manufacturing industrial detergents.
Diesel Fuel:Used as fuel in diesel engines, generators, and heating systems.
Chemical Industry Feedstock:Used in the production of various chemical products.
Paraffin Production:Used in the manufacture of industrial paraffins and related products.
