What Is Diesel Fuel Polishing?

Fuel polishing is a contaminant-removing technique that filters diesel fuel in storage tanks. Fuel filtration, also known as diesel fuel polishing or diesel cleaning services, eliminates water, microbiological particles, and sludge from on- and off-road diesel.

CommTank offers fuel polishing services as an alternative to our tank cleaning service when it makes more sense. Fuel polishing is preferred by mission-critical plants since it does not need any downtime. During filtration, the fuel system remains operational, resulting in a clean tank with fuel that performs like new.

The high expense of diesel fuel pales in comparison to the expenditures of repairing problems that arise due to improper fuel tank maintenance. Diesel fuel polishing can bring fuel quality back up to ASTM D975-10 standards.

Advantages of Fuel Polishing

  • Polishing extends the life of a fuel tank by maintaining the interior and removing sludge.
  • Polishing eliminates impurities and brings diesel fuel back into compliance with the ASTM D975-10 standard for on-road and off-road diesel.
  • No tank downtime is required for polishing, and the gasoline system can remain operational during the procedure.

What does it mean to polish diesel fuel?

The technical cleaning technique used to remove or filter microbiological contaminants from oil and hydrocarbon fuel in storage is known as fuel polishing. It is the process of removing water, silt, and microbial contaminants from diesel, red diesel, and biodiesel fuels. If stored fuels aren’t checked and treated on a regular basis, fuel contamination, also known as ‘fuel bugs,’ ‘diesel bugs,’ or’so-called algae,’ builds up over time. Before beginning fuel polishing, a fuel analysis should be performed so that the exact contamination problem may be addressed with a targeted remedy. After the fuel cleaning has been finished, a second fuel test should be performed to ensure the problem has been resolved.

Why is fuel polishing necessary?

What Is the Purpose of Fuel Polishing? It keeps your fuel from spoiling and, as a result, keeps your generator from breaking down when you need it most. Water, bacteria, rust, and sludge are captured in the filter system during fuel polishing.

How do you keep diesel fuel clean?

TO CLEAN FUEL TANKS AND PREVENT PREMATURE FUEL-FILTER PLUGGING, pump or drain excess water and fuel impurities from the bottom of the fuel tank until diesel fuel shows, if possible. Fill each 20 gallon of diesel fuel with the entire contents (16 ounces) of Clear-Diesel Fuel & Tank Cleaner.

TO KEEP A CLEAN FUEL TANK AND STABILIZE FUEL FOR LONG-TERM STORAGE, DO THE FOLLOWING: Fill each 40 gallon fuel tank with the entire contents (16 ounces) of Clear-Diesel. Diesel fuel should be added to the tank.

How do you clean diesel fuel?

Fill the tank with a few gallons of water and a scouring medium, such as shards of safety glass or clean gravel. Add a liquid soap with petroleum-cutting characteristics, such as Dawn, Ajax, or Palmolive, and rapidly swish it around in the tank.

Can gasoline be polished?

What is Fuel Polishing and How Does It Work? Fuel polishing is a cleaning technique for diesel fuel that involves withdrawing the fuel from the tank and filtering it back into the tank for a set period of time to eliminate contaminants. Because ultrafiltration of fluid across a semi-permeable membrane is analogous to removing contaminates from blood, this novel method of fuel remediation is commonly referred to as the dialysis method.

Is Fuel Polishing Effective on All Fuels? Most of the time, fuel polishing removes impurities and water from diesel fuel. We can supply you with ASTM-compliant analysis to demonstrate this.

Do you drain the tank of petrol and re-fill it with filtered fuel? Yes, we do in a lot of circumstances. We have vacuum trucks, gasoline trucks, and tankers that can remove all of the fuel, clean the tank, and re-inject it.

What sets DFS apart from its competitors? Our approach is unique! Our newly built equipment is the most up-to-date technology available today. We are one of the few companies who can handle tanks of all shapes and sizes. We’ve worked on tanks that were as small as 100 gallons and as large as 96,000 barrels. Call (888)620-6807 for a quote.

Is it possible to run our generator when fuel polishing? Yes. The diesel fuel in the tank is not used. The pollutants are the only thing that has been removed?

Do we still require a service if we have a stationary fuel polishing system? Yes! Many businesses believe that installing a fuel polishing system eliminates the need for expert services. This isn’t the case at all. Although it aids in the maintenance of clean fuel, there is no substitute for having a service conduct the work. It’s akin to vacuuming your home once a month and assuming that your carpet will never need to be professionally cleaned. Furthermore, because most systems filter gasoline daily without oversight, we have reacted to a number of spills caused by these systems.

Should a stationary fuel polishing system be installed? The tank, fuel, and configuration all play a role. Stationary fuel polishing systems can often cause more harm than good by suspending water in the fuel, which can lead to catastrophic failure. An on-site examination is highly recommended.

Is it possible for DFS to polish gasoline? NO! We strongly advise against polishing Gasoline. Because gasoline has a low flash point and ethanol has a weight similar to water, polishing it will be more of a disadvantage than an advantage.

Do we still need to clean our fuel if we add additives? Without a doubt. Additives can help to slow down the aging of fuel, but they do not eliminate all contaminants.

Is Fuel Polishing Effective? Absolutely! We have the evidence: ASTM testing, third-party testing, and a slew of white papers and analyses demonstrating that Fuel Polishing works.

How can we know that polishing has successfully remediated diesel fuel? With our mobile fuel lab, we test to ASTM standards on-site before and after to ensure that the fuel is suited for its purpose.

What is generator fuel polishing?

Fuel polishing is a cleaning procedure that eliminates any hazardous sediment from your generator’s fuel tank, which, if not removed, might cause problems with your backup power system. A fuel polish entails withdrawing the diesel from the storage tank, filtering it, eliminating the redundant fuel, and then refueling the tank with the remaining clean fuel.

Long-term storage of diesel in fuel tanks can lead it to deteriorate and get contaminated, which can harm a diesel generator and, in the worst-case scenario, create system failures that can be disastrous, especially for an emergency backup generator.

Fuel polishing also improves the efficiency of your generators by allowing you to use less fuel, saving you money and reducing the number of breakdowns.

How often should fuel be polished?

If the stored fuel is intended for backup power, we recommend doing it at least once a year. We recommend a treatment at least every two years in essential institutions such as hospitals and data centers to ensure that activities do not come to a standstill. What causes fuel contamination?

How do you remove sulfur from diesel fuel?

Sulfur has a deleterious impact on diesel fuel, as almost every vehicle owner has heard at some point in their lives. However, if you ask them what this influence is, they will not all know. So, what is sulfur so dangerous?

For starters, it encourages fuel oxidation, which pollutes the environment with exhaust fumes.

However, sulfur’s impact on diesel fuel has more than just negative implications.

It increases the lubricating characteristics of this oil, resulting in less engine structural wear.

As a result, while choosing fuel, it is best to find a “medium ground” that provides adequate lubricity while also minimizing environmental impact.

Fuel with a sulfur level of 0.15 to 1.5 percent is recommended by experts.

Desulfurization of diesel fuels is mostly done using physico-chemical and chemical processes nowadays in the refining sector.

A chemical process uses hydrotreating and sulfuric acid purification, while a physico-chemical method uses absorption and adsorption purification.

Cleaning with sulfuric acid is done by mixing processed diesel fuel with a 90-93 percent sulfuric acid solution at room temperature.

Purified oil and acid sludge are obtained after all chemical reactions are completed.

All of the unwanted contaminants are found in the latter.

It could theoretically be used to make sulfuric acid.

Sulfuric acid treatment is, in general, a complicated process that necessitates the use of large machinery.

In today’s world, hydrotreating is the most prevalent process for removing sulfur from diesel fuel.

This procedure is extremely costly.

The price of a hydrotreating unit is determined by its performance and the depth of processing required, and it can reach millions of dollars in theory.

The core of this strategy is based on hydrogen reacting with diesel fuel in the presence of certain compounds called catalysts.

We get hydrogen sulfide, ammonia, and water as a result of chemical reactions between hydrogen and sulfur, nitrogen, and oxygen components.

The high temperature (380-420oC) and pressure (up to 4 MPa) of the process, as well as the complexity of the hardware design, are all downsides of this approach.

However, in the current situation, the greatest disadvantage may be a significant anthropogenic impact on the ecological system as a result of toxic material emissions into the atmosphere and waste water.

Additional financial and material expenditures are necessary to offset the emissions created by hydrotreating petroleum products.

Adsorption treatment is accomplished by contacting diesel fuel with specialized adsorbents, such as bleaching clay or silica gel.

They absorb oxygenation, sulfur, and nitrogen compounds, as well as other contaminants that must be eliminated (for example, resin).

The elimination of hazardous components of diesel fuel is accomplished through absorption treatment.

Solvents include furfural, sulphovin, and nitrobenzene. The downside of this strategy is that the utilized solvent cannot be recovered, resulting in its entire loss and increased financial costs.

GlobeCore provides environmentally acceptable technology for removing hydrogen sulfide compounds and lowering sulfur content in diesel fuels.

It’s used in UVR-type facilities, which may also reduce wax content and remove unsaturated hydrocarbons from oil-based goods.

Diesel fuel that has been purified by GlobeCore facilities is once again marketable, does not re-oxidize, and does not darken.

  • Due to the option of selecting an automatic or semi-automatic mode, the procedure does not necessitate the presence of an operator at all times. It is only required when the plant is started and stopped, as well as when adsorbents are replaced.
  • The ability to use it in a variety of ways. When changing the type of cleansed, lightened, or recovered fuel, or mineral oil, a UVR-type plant does not require any technical management. Stopping the plant, switching to manual mode, pumping out petroleum residues from the system, and replacing the old adsorbent and filter are all that is required to move from one raw material to another.
