Fuel Blending

When we talk about fuel blending, we usually refer to the process that successfully manages to mix two or more products based on a specific percentage ratio. An example is that of the blend of diesel oil and FAME or petrol and ethanol, where we can clearly see the union of a hydrocarbon and a product of plant origin. 


The fuel blending solutions by ISOIL are designed to provide strategic and operational advantages, including:

  • cost savings on production time scales;
  • excellent fuel blend versatility;
  • high-quality standards of the blended product.

The Fuel Blending Process: How Does It Work?

The fuel blending process is a technique employed to combine different fuel stocks to produce a final product that meets specific requirements. To perform an optimal fuel blending process, it is fundamental to follow these steps.


Analysis Phase

First, you need to select different base stocks or raw fuels, such as naphtas, reformates, alkylates, and so forth. However, before blending, an assessment phase is performed to determine how these components will impact the output of the whole operation. 


In fact, each component has intrinsic properties that can influence the final result, in terms of: 

  • octane number
  • volatility
  • density
  • sulfur content
  • emissions profile.


Highly skilled technicians formulate a fuel blend recipe using advanced technology and mathematical models. Through complex calculations, it is possible to understand the quality of the resulting blend, its specific properties and, if necessary, adjust the formulation.


Processing Phase

The process takes place in blending tanks. There are two main methods:

  • batch blending, all the chosen components are mixed at once; 
  • inline blending, the components are continuously injected into a pipeline according to the formulation. 


Quality Testing & Distribution

After fuel blending, the final product undergoes further testing to ensure that it meets all specified quality and regulatory standards. Additional adjustments may be required


It is quite common to include additives in the blend to enhance certain features like stability, cold flow, corrosion inhibition.


Once the fuel blend resulting from the process has passed all the controls and tests, it is time to store it in tanks and distribute it to the market. Proper storage is the key to preserve the quality and integrity of the final product.


ISOIL Equipment Deals With Different Types of Fuel Blending 

Over the years, we have earned a specific know-how that allows us to perform the blending process with different types of fuel. In fact, ISOIL can deal with:

  • diesel fuel blending a specialized procedure that consists in merging various types of diesel oil to achieve a fuel mix with specific features. This method is executed by combining fossil-derived hydrocarbons with plant-derived products - such as biodiesel - to obtain a more environmentally friendly fuel.
  • bioethanol blending with gasoline is another sustainable alternative to traditional fuel, as bioethanol is a renewable source with lower emissions. It is mainly produced from organic materials like corn and sugarcane and, when blended, it increases the oxygen content of the gasoline, facilitating cleaner combustion while greatly improving engine efficiency and performance.
  • biodiesel blending with traditional diesel is an effective way to create a greener solution to conventional fuel sources, leveraging the organic and renewable nature of biodiesel. This fuel is produced with vegetable oils and animal fats, when blended, it enhances the environmental profile of diesel significantly reducing carbon footprint
