EN590 Dizel
EN590, European Union standardization for diesel fuel used in diesel vehicles. This fuel is formulated with specific physical and chemical requirements and characteristics aimed at reducing emissions, improving efficiency, and enhancing the performance of diesel engines. Some of these requirements and specifications include:
Sulfur content: EN590 diesel fuel must contain a maximum of 10 ppm sulfur for every kilogram of fuel. This reduction in sulfur content helps decrease emissions of sulfur oxides and mineral acids, which contribute to air pollution and acid rain.
Cetane number: The minimum cetane number for EN590 diesel fuel should be 51. The cetane number indicates the ignition quality of diesel fuel. Diesel fuel with a higher cetane number ignites faster, reduces engine noise, increases power, and decreases fuel consumption.
Water content: EN590 diesel fuel should contain a maximum of 200 ppm water for every kg of fuel. This reduction in water content helps reduce corrosion, fuel system degradation, microbial growth, and fuel filter plugging.
Fatty acid methyl ester (FAME) content: EN590 diesel fuel may contain up to 7% fatty acid methyl esters (FAME). These esters are produced from plant or animal oils and are considered renewable fuels. This addition reduces greenhouse gas emissions and improves fuel efficiency.
Bitumen
Bitumen is a black paste-like material primarily used for waterproofing and asphalt preparation. There are various types of bitumen, each with its specific applications. Speaking in more specialized terms, bitumen is a colloidal hydrocarbon compound, either of natural or synthetic origin. From a physical standpoint, bitumen is a substance that exhibits unique behavior at any temperature. At ambient temperatures, it behaves neither like an elastic nor a completely fluid substance but rather displays viscoelastic behavior, combining these two states.
Bitumen is typically a petroleum product produced in oil refineries. As the ambient temperature increases, bitumen solidifies. Further temperature increases result in it becoming a paste. As the temperature continues to rise, it becomes more liquid.
Waterproofing and adhesiveness are characteristics that make this material very versatile and widely used.

However, there are various types of natural bitumen found in nature. These materials are derived from the gradual transformation of crude oil and also from the long-term evaporation of its volatile components, resulting in what is known as natural bitumen. Natural bitumen can exist in a pure form in nature, which is referred to as lake bitumen. As you may know, this type of bitumen is found in the Behbahan Bitumen Lake in Iran and the Trinidad Bitumen Lake in America. Natural bitumen is more persistent than petroleum bitumen.Top of Form
base oil
Base oil is the same oil that is commonly used as the main additive in lubricating oils. Those involved in chemical manufacturing know well that base oils are the primary additives in lubricating oils by volume. On average, more than 95% of the composition of lubricating oil consists of base oil by weight.
Base oil is used in the production of automotive oils, diesel oils, industrial oils, lubricants, rubber materials, paraffin oil, white oil, and so on.
Interestingly, in the production of some lubricating oils (for example, hydraulic and compressor oils), 99% of the oil is base oil, with only 1% being additives. The majority of base oils worldwide are obtained as a result of petroleum refining.
1.SN150 base oil: Suitable for the production of lubricating oils and greases.
2.SN350 base oil: Suitable for the production of medium viscosity heavy-duty engine oils and gear oils.
3.SN500 base oil: Suitable for the production of medium and high viscosity industrial oils and chemical compounds.
4.SN650 base oil: Suitable for the production of high viscosity functional oils and heavy-duty lubricants.
