Understanding Ultra-Low Sulfur Diesel Fuel

Date:16-03-2022 | By: Redlines Diesel Trading

Diesel fuel contains sulfur, which comes from the crude oil source and might remain after refining. After combustion in the engine, the sulfur in the fuel generates particles, which are a major contributor to air pollution and the cause of engine damage. Prior to worldwide efforts to improve air quality and remove sulfur from gasoline, significant quantities of detergent additives were required in engine oil to protect engine components from sulfur damage. Fuel trading companies in UAE were looking for alternate solutions. The introduction of Ultra-low sulfur diesel fuel made a huge impact on the problems caused by sulfur. So read along if you are interested in Understanding Ultra-Low Sulfur Diesel Fuel.

What is Ultra-Low Sulfur Diesel?

Ultra-low sulfur diesel (ULSD) is diesel fuel with a maximum sulfur content of 15 parts per million (ppm). Sulfur levels have previously reached 3,000 ppm. A far more severe refining procedure, which involves catalytic cracking and hydrodesulfurization, is utilized, greatly destabilizing the gasoline and necessitating greater monitoring of fuel and fuel tank conditions. Although every gasoline must fulfill the ASTMD975 test criteria before leaving the refinery, it is difficult to ensure that it will arrive in the same condition. The Ultra-Low Sulfur Diesel fuel is constantly exposed to impurities as it travels via ships, tanker trucks, pipelines, and temporary storage tanks.

Why Was Reducing Sulfur Content in Diesel Fuel Important?

The required engine oil is heavily influenced by gasoline quality, notably sulfur levels. Because fuel quality can have an influence on engine hardware, the oil must be designed to guard against these effects. It is therefore critical to use the proper metric for how the oil works.

The amount of sulfur acids produced by today's ULSD fuel is so low that there is no longer a requirement for significant quantities of detergents that produce high TBN. Protection against organic acid corrosion, on the other hand, has become a more important necessity of contemporary engine oil.

To obtain maximum performance with today's ULSD gasoline, engine oil compositions with a complex combination of detergent, antioxidant, and corrosion inhibitor chemicals are required.

Benefits of Low Sulphur Fuels

1. Lower Costs

One of the most significant advantages of utilizing ultra-low sulfur oil for your fuel tank is that it is less expensive than standard heating oil since it burns more effectively. In general, ultra-low sulfur oil is somewhat more costly per gallon than regular oil. However, it is so much more efficient than when you fill your fuel oil tank, your cost will be reduced.

2. Enhanced Safety

Ultra-low sulfur oil is a safe and stable fuel. Because it does not ignite when exposed to a flame, this is a significant advantage when deciding what fuel to use to heat your house. The oil must be heated above 140 degrees Fahrenheit before it may begin to burn.

As a result, there is no risk of an explosion when kept for extended periods of time in a fuel-oil tank on your property. Some conventional heating fuels have the potential to explode and cause significant harm to your house or family.

3. Eco-friendly

Ultra-low sulfur oil is an excellent alternative for homeowners concerned about their environmental effects. By all accounts, this oil is a very clean alternative. Particulates are nearly non-existent in ultra-low sulfur heating oil. That implies that when you burn it, you have little impact on the environment. When compared to ordinary heating oil, using this heating oil reduces nitrous oxide emissions by 10%. It will cut your sulfur dioxide emissions by 75%.

4. Enhanced Efficiency

It is more efficient to use ultra-low sulfur heating oil than ordinary heating oil. This oil burns more cleanly. A full tank of ultra-low sulfur oil, for example, is 40% more efficient than natural gas.

5. Longer Life for the Equipment

Your heating equipment will last longer since there will be less residue in your system. You do not remove all of the dirt and crud off of your heat exchangers. Your home heating system's interior workings remain clean.

6. Switching to Ultra-Low Sulfur Oil is Simple

One of the most significant advantages of using ultra-low sulfur oil in your fuel oil tank is that it is still heating oil. That is, no special or new equipment is required. Your current home heating system is ready to make the conversion to this cleaner, less expensive heat source.

There are no additional converting fees. Your current system only needs to be emptied and refilled with the new oil. Your heating firm can accomplish this swiftly and easily, causing no disturbance to you or your family.

How Sulfur Content in Diesel Fuel Impacts Engine

After combustion, sulfur from diesel fuel produces sulfuric acid, which causes corrosive wear on an engine's metal surfaces. Corrosion of a surface inside a dynamic system, such as the cylinder wall/liner, can result in corrosive wear; surface corrosion layers are removed by sliding or abrasion.

All acids produced within the engine have the potential to cause corrosion, although the danger of corrosion varies according to their acidity. The acidity of a fluid is determined by the pH of the combination. The danger of corrosion is increased by both the concentration of acid present and the strength of the acids in the combination.

However, because of the extensive processing necessary to remove huge levels of sulfur from the oil, ULSD has a lower energy content (BTUs), resulting in a 1 to 2 percent worse fuel economy. It also necessitates the use of more expensive oil. But compared to the benefit it brings to the table, fuel suppliers in Dubai like Redlines Diesel prefer to supply the ULSD fuel rather than the alternative fuel.
