At BG OF Ireland we offer a complete service for your bulk storage facilities to ensure product quality and environmental compliance.
Most of us know that clean fuel is necessary for the high-pressure common rail fuel injectors (HPCR) used in today’s Tier 4 Final engines. Fuel system pressures approaching 40,000 psi require particle filtration as small as one or two microns.
The problem is that as fuel system requirements are becoming more stringent, actual diesel fuel quality is going down.
Maintaining diesel fuel quality and cleanliness has never been easy. To give you an idea of how long the industry has been dealing with this issue, a Caterpillar Operators Manual published 90 years ago stated “dirt and water causes 90 percent of all the problems with diesel fuel systems.”
Water + diesel = microbes and sludge
The presence of water in diesel fuel also adds to the problem of microbial growth. Fungus, mold and other types of bacteria can flourish and use diesel fuel as a food source. The residue and resulting bonding from this bacteria damages fuel quality, clogs filters and can lead to equipment failure.
Diesel fuel will always contain a certain level of water content. The objective is to keep this water content within suitable limits, which is well below the saturation point. Since some water is inevitable, one solution is a routine treatment of fuel storage tanks with a biocide treatment program to kill tank bacteria microbes.
Lubricity challenges resulting from ULSD
In 2006, the U.S. Environmental Protection Agency mandated the shift from low sulfur to ultra low sulfur diesel (ULSD), reducing sulfur in the fuel from 500 parts per million (ppm) to 15 ppm. After the transition to ULSD people started complaining about higher than normal corrosion in diesel fuel storage tanks, fuel dispensing pumps and related piping configurations.
One of the concerns with ULSD fuel was lack of lubricity. The cheapest way to remove sulfur during refining involves hydrotreating, a process that removes sulfur and cetane by treating it with hydrogen. Unfortunately, hydrogen is highly reactive and also reduces the lubricity, or lubrication properties, of the end-product.
Sulfur serves as a lubricating medium and the reduction of that sulfur (from 500 ppm to 15 ppm) causes a reduction in lubricity. After numerous complaints, refiners started adding lubricity additives to the process to compensate. Many people who service equipment still complain of evidence of poor lubricity, especially in older engines.
Our Solution is to Clean out the Storage Tank and then clean the whole injector system with both Diesel Care PN 229 as Demonstrated below and Diesel PN 244. We also provide a heavy duty Cleaner to your storage tanks Diesel Care With Lubricity PN 227. This ensures that all vehicles that have been cleaned remain clean restoring both Power and Fuel Consumption.
