DIESEL FUEL POLISHING SYSTEMS

Diesel fuel polishing systems are crucial for maintaining fuel quality and ensuring the smooth operation of diesel engines. These systems remove contaminants and water from diesel fuel, preventing engine damage and enhancing performance.

Diesel fuel polishing systems play a vital role in maintaining fuel quality and protecting diesel engines from damage. By employing filtration, water separation, and continuous circulation methods, these systems contribute to improved engine performance, longevity, and cost savings. When selecting a polishing system, consider factors such as flow rate, filtration efficiency, and monitoring capabilities to ensure compatibility and effectiveness for your application.

YOUR DIESEL NEEDS YOUR ATTENTION

Diesel fuel is a mixture of hydrocarbons obtained by distillation of crude oil. The important properties which are used to characterize diesel fuel include cetane number (or cetane index), fuel volatility, density, viscosity, cold behavior, and sulfur content. Diesel Fuel has been updated with environmental concerns and governmental regulations over time and has now created a situation that must be considered in storage, particularly in medium to long term, because it has a shelf life and breaks down by aging.

The diesel composition, which is a fuel of fossil origin, contains many aerobic and anaerobic bacteria spores and fungus. Especially where water is present, these bacteria and fungi are in a logarithmic growth environment. If not continuously maintained, they can cause all the fuel volume in a storage tank to become infected. As a result, microorganism infection, which turns into an organic contamination, poses a risk for the installations, extending from the tank to the combustion chamber through injectors which brings a significant chance of engine failures.

Diesel fuel attracts many physical pollution factors during the entire trip from the refinery to the end user’s storage tank. Unwanted agents such as solid particles, dust, sand, ferrous, etc. accumulate in the tank as a result. In addition to the catastrophe that blocks or ruins the filters and injectors, they also cause the formation of suitable habitats for organic pollution and bacterial growth. Apart from solid dirt, water; both in free and emulsified form, is the most undesired factor of fuel. Water is the last thing we want to see somewhere close to a combustion chamber with high pressure and temperature.

The most important feature that makes fuel usable is the calorific composition and combustibility. If the fuel -treated only by filters physically- is not in proper chemistry cannot create a combustion. Meaning, visibly clean fuel not a guarantee for an appropriate operation of emergency power generators. The end user must acknowledge that diesel is a complete set with its correct chemistry, cetane, viscosity, volality, and aromatics. Therefore, Fuel Maintenance should cover all.

Fuel specifications changed due to environmental concerns related to diesel fuel. The amount of sulfur in the fuel was gradually reduced by the precise parameters of ASTM D975 and EN590. While becoming more environmentally friendly, the new ultra-low sulfur diesel has lost one of its essential lubricants. Ultra-low sulfur diesel fuels have a significantly shorter storage life as well because microbial issues are more likely to take hold of them.

Biodiesel Blending, a long-standing agenda in the United States and the European Union, introduces a number of unique challenges, including:

  • Oxidation stability, both under thermal and long-term storage conditions
  • Cold flow characteristics and filterability
  • Propensity for supporting microbiological growth
  • Tendency to increase the dissolved water content and degrade the water-shedding ability of diesel fuels
  • Compatibility with materials commonly used in refinery, distribution, and fuel-supply systems

All of these challenges can only be effectively managed if proper housekeeping practices are followed.

Engines and injection systems changed. Market demands and state regulations pushed manufacturers for more economical consumption, better combustion, and higher power. We, therefore, have now TIER IV and TIER V engines with much more precise injection systems than we had ten years ago, with fuel lines operating at higher pressures and temperatures. It is clear that the traditional preventive maintenance practices will be inadequate in the infrastructure with these engines.

The needs of today’s business world have changed. Now, continuity is more important than it was before. And now a downtime is much more expensive than it has ever been before. For this reason, designers and facility managers are extra-careful for sizing of emergency power supply systems, redundancy planning, regular tests and maintenance practices.

What happens if your facility suffers a complete blackout for 1 hour? If the answer scares you because you are running a mission-critical facility or this would incur huge financial losses, then you might be running a risky operation.

Change Your Maintenance Perspective

In fact, the technical staff of the critical facilities applies calculated predictions and preventive maintenance with very clearly defined and planned procedures. Especially at Tier III and Tier IV plants, these practices are also audited by independent parties with almost no gaps. Generators’ maintenance is carried out with high precision in the same way.

On the other hand, maintenance of the diesel fuel stored for the generators is generally skipped, or simple physical cleaning methods like annual tank cleaning apply. However, diesel has a shelf life and may become unusable both physically and chemically when left without any care. This may result in a costly catastrophe when there is an emergency power need.

You Need Full and Continuously Protected Fuel, Not Only Polishing

While the generators are operating, line filters on the fuel transfer lines provide only limited protection. In this case, the limited protection raises concerns about how long the generators must run and how much contamination the filters can handle. This situation is not acceptable for critical facilities, and maintaining an optimum quality of the fuel in the tank is a must.

In the long run, a permanently installed complete off-line fuel maintenance system (fuel polishing system) is safer and more cost-effective for end-users than an annual tank cleaning practice.

How Diesel Fuel Polishing Systems Work:

  1. Filtration: Diesel fuel polishing systems utilize various filtration methods to remove impurities from fuel. This typically involves passing the fuel through multiple filters of varying micron ratings to capture particles of different sizes.
  2. Water Separation: Water can accumulate in diesel fuel tanks due to condensation or leaks. Fuel polishing systems incorporate water separators to effectively remove moisture from the fuel, preventing corrosion and microbial growth.
  3. Continuous Circulation: Many diesel fuel polishing systems operate on a continuous circulation basis. This means that fuel is continuously circulated through the filtration and water separation components, ensuring that the fuel remains clean and free of contaminants.

Benefits of Diesel Fuel Polishing Systems:

  1. Engine Protection: Clean fuel is essential for the proper functioning of diesel engines. Fuel polishing systems help protect engines from damage caused by contaminants such as dirt, rust, and microbial growth, prolonging engine life.
  2. Improved Performance: By maintaining fuel quality, polishing systems contribute to improved engine performance and efficiency. Clean fuel allows engines to operate at optimal levels, leading to better fuel economy and power output.
  3. Cost Savings: Investing in a diesel fuel polishing system can result in long-term cost savings. By preventing engine damage and reducing the need for frequent maintenance, these systems help minimize downtime and repair expenses.

Key Considerations When Choosing a Diesel Fuel Polishing System:

  1. Flow Rate: Consider the flow rate requirements of your diesel fuel system when selecting a polishing system. Ensure that the system can accommodate the flow rate of your fuel system to maintain adequate fuel supply during operation.
  2. Filtration Efficiency: Look for polishing systems with high filtration efficiency to effectively remove contaminants from the fuel. Systems with multiple filtration stages and fine micron ratings can provide superior cleaning performance.
  3. Monitoring and Maintenance: Choose a system that offers monitoring capabilities and easy maintenance procedures. Features such as filter condition indicators and accessible filter replacement options can simplify maintenance tasks and ensure optimal system performance.

In summary, diesel fuel polishing systems play a vital role in maintaining fuel quality and protecting diesel engines from damage.
