D2 Diesel Gas Oil, also known as Diesel Fuel No. 2 or Gasoil, is a middle distillate fuel derived from crude oil through the refining process. It is widely used in various applications due to its efficiency and energy content. Heres a detailed description: 1. Composition: Hydrocarbons: Primarily composed of alkanes, cycloalkanes, and aromatic hydrocarbons Sulfur Content: Historically higher, but modern ultra-low sulfur diesel (ULSD) contains less than 15 ppm sulfur. Additives: May include detergents, dispersants, and anti-foaming agents to enhance performance and reduce emissions. 2. Physical Properties: Appearance: Clear to amber liquid. Density: Approximately 0.85 kg/liter. Viscosity: Higher than gasoline, providing better lubrication for fuel injection systems. Flash Point: Typically above 52�°C (126�°F), making it safer to handle than gasoline. Cetane Number: Ranges from 40 to 55, indicating good ignition quality. 3. Uses: Transportation: Widely used in diesel engines for cars, trucks, buses, and trains. Industrial: Powers generators, construction equipment, and agricultural machinery. Heating: Used in some heating systems, though less common than heating oil. D2 Diesel Gas Oil is a versatile and efficient fuel essential for a wide range of applications. Its properties and performance make it a critical component in the global energy landscape, and ongoing advancements aim to reduce its environmental impact.
Petroleum Coke (Petcoke) is a carbonaceous solid material derived from oil refinery coker units or other cracking processes. It is a byproduct of the oil refining process, specifically from the thermal decomposition of heavy residual oils. Heres a detailed description: 1. Composition: Primarily composed of carbon (90-95%).Contains small amounts of sulfur, nitrogen, and metals (e.g., vanadium, nickel).Low in ash content compared to coal. 2. Types of Petroleum Coke: Fuel-grade Petcoke: Used as a fuel in power plants, cement kilns, and industrial boilers due to its high calorific value. Calcined Petcoke: Produced by heating raw petroleum coke to remove volatile matter and moisture and used in the production of anodes for the aluminum and steel industries. 3. Physical Properties: Appearance: Black or dark gray solid.Texture: Can range from a porous, sponge-like material to a hard, dense substance. Density: Varies depending on the type (fuel-grade or calcined). Petroleum coke is a valuable industrial material, but its use must be balanced with environmental considerations to minimize its impact.
Diesel EN590 10ppm is a high-quality automotive diesel fuel that complies with the European standard EN590. The "10ppm" indicates that the fuel contains a maximum of 10 parts per million (ppm) of sulfur, making it an ultra-low sulfur diesel (ULSD). Hereâ??s a detailed description of its key characteristics: 1. Sulfur Content: 10ppm Sulfur: This fuel contains no more than 10 parts per million of sulfur, significantly reducing harmful emissions such as sulfur oxides (SOx) and particulate matter (PM). This makes it environmentally friendly and compliant with stringent emission regulations. 2. Cetane Number: Minimum 51: The cetane number is a measure of the fuel's ignition quality. A higher cetane number (minimum 51 for EN590) ensures better combustion, smoother engine operation, and reduced engine noise. 3. Density: 820-845 kg/m�³ at 15�°C: The density of EN590 diesel is specified within this range to ensure optimal energy content and efficient combustion. 4. Distillation: 95% Recovery at 360�°C: This indicates that 95% of the fuel evaporates at or below 360�°C, ensuring proper volatility for efficient engine performance. 5. Cold Flow Properties: Cloud Point: Varies depending on the climate (e.g., -12�°C for winter grades). CFPP (Cold Filter Plugging Point): Ensures the fuel remains fluid at low temperatures, preventing filter clogging in cold weather. 6. Lubricity: HFRR Wear Scar Diameter (WSD) â?¤ 460 �µm: Ensures adequate lubricity to protect fuel injection systems from wear and tear, even with the low sulfur content. 7. Polycyclic Aromatic Hydrocarbons (PAH): Maximum 8% by mass: Limits the presence of PAHs, which are harmful to both human health and the environment. 8. Additives: May contain performance-enhancing additives such as detergents, corrosion inhibitors, and stabilizers to improve fuel efficiency, reduce emissions, and maintain engine cleanliness. 9. Environmental Benefits: Reduced Emissions: The low sulfur content and high cetane number contribute to lower emissions of CO2, NOx, and particulate matter, making it compliant with Euro 5 and Euro 6 standards. Compatibility with Advanced Emission Control Systems: Suitable for use in modern diesel engines equipped with particulate filters (DPF) and selective catalytic reduction (SCR) systems. 10. Applications: Automotive Use: Primarily used in road vehicles, including cars, trucks, and buses. Industrial Use: Can also be used in non-road machinery and equipment, provided they are compatible with ULSD. 11. Storage and Handling: Stability: EN590 diesel is designed to remain stable during storage, with additives to prevent oxidation and degradation. Safety: Standard safety precautions for handling diesel fuel apply, including proper ventilation and avoidance of ignition sources. 12. Compliance: EN590 Standard: Fully compliant with the European standard EN590, ensuring consistent quality and performance across the European Union and other regions.
