 COMMON SPECIFICATIONS

• Penetration Grade: This specification measures the hardness or softness of bitumen by the depth in tenths of a millimeter to which a standard needle will penetrate vertically under standard conditions of loading, time, and temperature. Penetration grades are commonly used for road construction and paving.
• Viscosity Grade: This specification measures the viscosity or flow resistance of bitumen at a specific temperature. Viscosity grades are commonly used for industrial applications, such as roofing, waterproofing, and adhesives.
• Performance Grade: This specification measures the physical properties of bitumen, such as stiffness, elasticity, and thermal susceptibility, that affect its performance in extreme weather and traffic conditions. Performance grades are commonly used for high-traffic highways and airports.
• Oxidized Bitumen: This specification refers to bitumen that has been chemically modified by adding air or oxygen to increase its softening point, durability, and aging resistance. Oxidized bitumen is commonly used for roofing, waterproofing, and insulation.
• Cutback Bitumen: This specification refers to bitumen that has been mixed with a solvent, such as kerosene or diesel, to reduce its viscosity and make it easier to handle and apply. Cutback bitumen is commonly used for spraying and painting applications.

• API gravity: This refers to the measure of how heavy or light crude oil is, and is determined by its density relative to water. The API gravity scale ranges from less than 10 (very heavy) to more than 50 (very light).
• Sulfur content: Sulfur is a common impurity in crude oil that can cause environmental and health problems when burned. Therefore, the sulfur content in crude oil is often limited to a certain level (usually less than 0.5-3.5% depending on the region and regulations).
• Distillation range: This refers to the range of temperatures at which different components of crude oil evaporate. The distillation range is important for determining the yield and quality of different refined products.
• Pour point: This refers to the lowest temperature at which crude oil will flow, and is important for ensuring that crude oil can be safely transported and stored in cold climates.
• Viscosity: This refers to the resistance of crude oil to flow, and is important for determining the pumping requirements and ease of transportation.
• Asphaltene content: Asphaltenes are complex organic compounds that are a natural component of crude oil. High asphaltene content can lead to fouling and corrosion in refining equipment, so it is often limited to a certain level.
• Water and sediment content: Crude oil can contain water and sediment, which can cause operational problems during transportation and refining. Therefore, the water and sediment content is often limited to a certain level.

Overall, crude oil specification can vary depending on the region and the type of crude oil being produced. Oil producers, refiners, and traders must ensure that crude oil meets the required specifications to ensure safe and efficient transportation and processing.

STANDARD SPECIFICATIONS

• Density: The density of Virgin Fuel Oil D6 typically ranges between 0.95 to 0.99 g/cm³. This high-density characteristic makes it a potent energy source, as it contains a substantial amount of energy per unit volume.
• Sulfur Content: Virgin Fuel Oil D6 has a sulfur content that typically falls within the range of 2.0 to 3.0 weight percent. This moderate sulfur content distinguishes it from lower quality fuel oils and makes it suitable for various industrial applications.
• Flash Point: The flash point of Virgin Fuel Oil D6 is usually above 60°C (140°F). This property ensures safe handling and transportation, reducing the risk of combustion during storage and distribution.
• Viscosity: D6 fuel oil exhibits a high viscosity, which means it is relatively thick and flows slowly compared to lighter fuels. This viscosity is crucial for certain industrial processes, ensuring optimal combustion and heat generation.
• Combustion Properties: Virgin Fuel Oil D6 offers a high calorific value, making it an excellent choice for power generation and industrial heating applications. Its efficient combustion provides a reliable and steady source of heat and power.
• Compatibility: D6 is generally compatible with various burners and fuel systems, allowing seamless integration into existing infrastructure across different industries.

STANDARD SPECIFICATIONS

• Sulfur Content: ULSD contains a maximum of 15 parts per million (ppm) of sulfur. This is a significant reduction from the previous standard for low sulfur diesel, which contained up to 500 ppm.
• Environmental Benefits: The primary benefit of reducing sulfur content in diesel is to decrease emissions of sulfur oxides (SOx), which can contribute to acid rain and respiratory problems. Additionally, ULSD allows the use of advanced emission control systems in diesel vehicles, which can further reduce harmful emissions.
• Mandates: Many countries have mandated the use of ULSD. For instance, in the U.S., as of October 15, 2006, the U.S. Environmental Protection Agency (EPA) mandated that the majority of diesel fuel produced or imported be ULSD.
• Lubricity: Sulfur can provide some lubricity to diesel fuel, so the reduction in sulfur content can lead to reduced lubricity in the diesel fuel. To address this, additives might be used to restore the necessary lubricity to ULSD.
• Compatibility: Most modern diesel engines are designed to use ULSD. However, older diesel engines can also run on ULSD. If you have an older diesel vehicle, it’s essential to check if any modifications or precautions are needed.
• Cost: Initially, when the transition to ULSD was being made, there was a slight cost increase due to the refining processes required to remove sulfur. Over time, as the production infrastructure adapted and economies of scale were achieved, the price difference between ULSD and previous diesel types became less significant.
