Gas oil 500
Gas oil 500 ppm, commonly known as diesel fuel with a sulfur content of 500 parts per million, is a middle distillate petroleum product widely used in diesel engines and heating applications.
Specifications
• Sulfur Content: Maximum of 500 ppm (0.05% by weight).
• Cetane Number: Minimum of 45, indicating good ignition quality.
• Density at 15°C: Ranges from 820 to 860 kg/m³.
• Flash Point: Minimum of 54°C, ensuring safe handling and storage.
• Viscosity at 40°C: Between 2.0 and 5.5 cSt, suitable for efficient fuel injection.
• Cloud Point: Maximum of 2°C, affecting performance in cold climates.
• Pour Point: Maximum of 3°C, indicating the lowest temperature at which the fuel remains fluid.
Note: Specifications may vary slightly based on regional standards and refinery processes.
Applications
• Transportation: Fuel for diesel-powered vehicles such as trucks, buses, and marine vessels.
• Industrial Machinery: Powers equipment like generators, construction machinery, and agricultural vehicles.
• Heating: Used in boilers and furnaces for residential and industrial heating.
Advantages
• Energy Efficiency: Diesel fuel contains approximately 10% more energy per gallon than gasoline, leading to better fuel economy.
• Engine Performance: Higher cetane numbers contribute to smoother engine operation and improved combustion efficiency.
• Availability: Widely accessible in many regions, supporting various sectors of the economy.
Environmental Considerations
While gas oil 500 ppm has a moderate sulfur content, it produces higher sulfur oxide (SOx) emissions compared to ultra-low sulfur diesel (ULSD) fuels with 15 ppm sulfur or less. SOx emissions contribute to environmental issues such as acid rain and air pollution. Consequently, many countries are adopting stricter regulations to limit sulfur content in diesel fuels, promoting the transition to cleaner alternatives.
Regulatory Standards
• United States: The Environmental Protection Agency (EPA) mandates the use of ULSD with a maximum sulfur content of 15 ppm for on-road and non-road diesel engines.
• European Union: The EU requires diesel fuels to have a sulfur content not exceeding 10 ppm, aligning with Euro VI emission standards.
• Other Regions: Some areas may still permit the use of 500 ppm sulfur diesel, but there is a global trend toward adopting lower sulfur fuels to meet environmental objectives.
