A Complete Solution for Fuel Tank Sludge

Tiffany T. - Friday, April 12, 2013

The following article is provided by CAT's Electric Power Advisor website. Click here to see original article.

"Preventive maintenance for generator sets should include a check of fuel condition. Clean fuel going into a tank does not assure clean fuel coming out. Condensation can occur in fuel tanks, whether a generator set is in regular use or sits idle for lengthy periods. Microbial growth can occur with the buildup of water. As the microbes feed on fuel and water, waste falls to the bottom of the tank. These microbial droppings are sometimes referred to as algae growth, but it bears no resemblance to real algae. It is sludge-like in nature and acidic, and can cause significant damage to engines.

This waste material can not only clog fuel filters, it can damage fuel injectors, causing downtime and expensive repairs. There is only one complete way to clean your fuel of microbial sludge – fuel polishing. Before discussing polishing, consider the drawbacks to partial steps that are not as effective. You can drain water and sludge from the bottom of the fuel tank or put biocides in the tank. Draining the tank removes most of the sludge but doesn’t remove entrained water, allowing new microbial growth. Biocides kill microbes but do not address the issue of existing sludge. And when additional fuel is added to the tank, the sludge is re-suspended.

With stricter environmental requirements, tight fuel system tolerances and pressures approaching 30-thousand psi, the smallest of contaminants or emulsified water can damage the fuel injectors and/or clog fuel filters. Fuel polishing removes the particulate matter and entrained water to greatly reduce the possibility of damage to fuel system parts. The process essentially loops diesel fuel out of and back into the fuel tank. There are three stages as the fuel is looped through the system – a centrifuge, a conditioning magnet and filters. By using this complete process to treat fuel, you eliminate the need to drain tanks.

You can make arrangements to polish fuel in one of two ways. You can add a polishing unit to your tank on site or you can include the process in preventive maintenance agreements to be performed at prescribed times. Either way, the cost is relatively inexpensive when compared to the damage the contaminated fuel can do to engines, and the cost of renting generator sets when downtime occurs.

When you consider fuel polishing, remember to use a system that includes all three stages of treatment. Some competitive offerings simply put a hose on the bottom of tanks and suck sludge from the bottom. As mentioned earlier, that is not a total solution and certainly does not remove entrained water. Remember, fuel polishing does not replace, but rather augments the filtering of fuel as it enters the tank.

Fuel polishing is an important part of your fuel quality management and will help generator sets perform up to expectations, giving you fewer worries.  Please contact us for more information.

The Low-Down on Ultra-Low-Sulfur Diesel Boat Fuel

The Low-Down on Ultra-Low-Sulfur Diesel Boat Fuel - Anything to Worry About?

http://www.boatus.com/seaworthy/magazine/SeaOct11_UltraLowSulfurDiesel.pdf

ALEXANDRIA, Va., November 17, 2011 - As a way to reduce particulate matter, ultra-low-sulfur diesel (ULSD), with only 15 ppm or less of sulfur, was mandated for use in most vehicles, boats and machinery as of December 2010. As a practical matter, however, ULSD has been around since late 2006 when 2007 model year vehicles with more advanced emissions control devices began requiring its use in cars. And since most fuel refiners don't have the capacity to offer more than one type of diesel, it's also been sold at marinas ever since.


During that time, the BoatUS Damage Avoidance Program has kept a close look out for any potential problems with the newer, environmentally-friendly fuel. Recently, the boat owner association's Damage Avoidance Program publication, Seaworthy, The BoatUS Marine Insurance and Damage Avoidance Report, investigated the issue and has these findings to share:

Lubricity: In diesel engines, having enough "lubricity" in the fuel is critical - without it, the engine would grind itself to a premature death. A lot of publicity has been given to ULSD because the process of removing sulfur from diesel fuel also removes much of the fuel's lubricity. Contrary to what some have said, however, lubricity is not a problem with ULSD. Minimum lubricity is a requirement of the ASTM-D975 diesel fuel standard and oil companies typically use a synthetic additive to return fuel to its pre-ULSD lubricity levels.  

Cetane: All diesel fuel must have a cetane rating of at least 40. Most regular diesel fuel has a cetane rating of 43 to 45, which should be fine for most boat engines.  The good news is that the cetane numbers remained the same with ULSD.

Gaskets: When the transition was made to low-sulfur diesel (LSD) in 1993, there were problems with leaking gaskets. Newer gaskets that resist leaking were developed, but there were some fears that the gaskets might not stand up to ULSD. After talking to numerous marina owners and engine manufacturers, leaking gaskets don't appear to be a problem.

Water and "Bugs": Microbial growth - bugs - need water to grow and have always been a concern with diesel fuel. ULSD holds less water than older, higher-sulfur fuels, which means that any water entering the tank is less likely to be absorbed and instead more likely to become a breeding ground for bugs. Biocides (and cold weather) kill the bugs but their tiny little carcasses pile up in funereal goo at the bottom of the tank. Tanks may need to be cleaned more often to prevent clogged filters and corrosion. The best defense is to keep tanks as full as possible (especially over winter storage) and keep a routine eye on the water separator.

Fuel Polishing - Keeping Genset Fuel Flowing During Disasters

Keeping Genset Fuel Flowing During Disasters
Developing A Strategy To Ensure The Availability Of Fuel For Your Generator System Is A Key Element Of Disaster Planning.

By Robert M. Menuet, PE, GHT Limited, Arlington, Va.
06/01/2011

Originally published at: Consulting-Specifying Engineer

Mr. Menuet states that as part of your disaster plans you should "consider installing a fuel filtering or polishing system that will remove moisture and help prevent fuel degradation. Sediment that can build up in the bottom of storage tanks can be stirred up when fuel is delivered, often resulting in clogged filters and injectors, or decreased engine performance.

Fuel polishing and filtration helps minimize this buildup. Also consider fuel additives that will prolong fuel life, suspend contaminants so they can be trapped by the system filters, protect against corrosion, and prevent biological growths."

Full Article
Our commercial, government, and institutional operations depend on the continuous availability of electrical power to run critical equipment. Prolonged, large-scale power outages, though rare, have significant financial and service delivery impacts. You need to be ready when disaster strikes.

Disasters vary in type and severity. Fuel supply planning for local severe weather events and regional blackouts is vastly different from the strategies required to defend against an unforeseeable terrorist attack or an extraordinary natural catastrophe such as Hurricane Katrina. The considerations outlined in this article are intended to guide you through the planning process to defend against reasonably predictable disasters.

Diesel vs. natural gas

Diesel-fueled generators are better suited for larger power requirements than natural gas-powered generators, yet require more physical space and maintenance to sustain a reliable fuel source. Building owners typically select natural gas generators when they require a lower initial capital investment and prefer not to maintain an on-site fuel supply.

Because natural gas is supplied by the local utility and delivered underground, the primary factor that building owners can control in relation to disaster defense is the purchase of non-interruptible service. Your utility will typically charge a slightly higher rate in exchange for a guarantee of fuel availability during a local disaster event, but many owners find this preferable to managing a diesel fuel supply for their generator.

When choosing between natural gas and diesel, it is important to note that natural gas generators may not satisfy local life safety requirements. If the utility source is not deemed reliable for emergency operations by the local authority, diesel engine generators are generally the only practical alternative.

For buildings that shelter critical business functions or have other high availability requirements, the decision to use an on-site diesel-powered generator is often made as part of overall disaster planning. Once this choice is made, there are numerous factors that can influence the configuration of the fuel supply. Considerations that can make this process more manageable include:

  • Fuel quantity
  • Refueling availability
  • Storage and compartmentation
  • Fuel quality
  • Safety and security

Fuel quantity

Identifying the amount of fuel needed to power your critical equipment during a reasonably predictable natural catastrophe is the first step. A rough consumption calculation for diesel generators is 7 gallons of fuel per hour for each 100 kW of generator rating; i.e., a 200 kW generator would consume 14 gallons of diesel fuel per hour. A typical goal for on-site storage is three days’ worth of fuel. A site requiring a 2 MW generator installation should have approximately 10,000 gallons of available stored fuel to provide a three-day supply. To ensure the necessary amount is on hand in the event of a disaster, you should factor engine exercising into your equation, and understand that refilling a partially depleted storage tank may not be practical until sufficient fuel is depleted to justify a fuel delivery. Purchase a storage system that will accommodate your disaster-threshold fuel plus the amount you will consume for engine testing as part of regular maintenance.

When determining the amount of fuel to store on-site, you must consider the criticality of your location and the nature of your operation at the site. If your facility provides critical functions required for your business that are not duplicated in another location, a larger quantity of fuel should be considered to ensure continued operations during an extended power outage. Consider the impact an extended utility outage would have on your organization’s bottom line. The data center of an online retailer would likely face far greater revenue losses during an extended power outage than the administrative office of a sales force that telecommutes and travels on a regular basis. Storing fuel can be expensive, so a business case should be developed that considers capital expenses and risk factors. Weigh the installation costs and maintenance requirements of storing fuel against the financial impacts of downtime—including the direct costs of lost revenue, recovery of operations, and the potential loss of customers.

According to the American Red Cross, “As many as 40% of small businesses do not reopen after a major disaster like a flood, tornado, or earthquake. These shuttered businesses were unprepared for a disaster; they had no plan or backup systems.”

Refueling availability

Refueling availability will impact your decision on how much fuel to store on-site. Is it financially and logistically feasible to store all or some of the desired amount in your building or on your property? Can you arrange to have a supplier outside of the region bring fuel when needed? In the second scenario, the fuel supplier down the street may be affected by the same natural disaster, so arranging delivery assurances from several geographically disparate suppliers may make sense. Selecting remote suppliers that use different transportation routes can further ensure refueling availability when a disaster has a widespread impact. Typically it is not practical—logistically or economically—to store more than several days’ supply on-site, so a balance between on-site storage and delivery assurances from suppliers should position you to survive an extended loss of electrical power.

Storage and Compartmentation

On-Site Storage—For the fuel you store on-site, the first consideration is conforming to local and state codes, Environmental Protection Agency (EPA) regulations, and National Fire Protection Association guidelines. Codes are intended to safeguard buildings and their occupants, while EPA is primarily concerned with the environmental impact of spills. Sustainable design certifications that encompass building energy usage, such as the U.S. Green Building Council LEED program, may also influence how much and where the fuel is stored.

The amount of on-site fuel storage will likely dictate storage locations and configurations. Large amounts of fuel are typically stored outside the building, either in above- or below-ground tanks. Below-grade storage requires EPA compliance for leak monitoring, and may necessitate groundwater monitoring and other spill detection methods. Local and state codes may have additional requirements for outdoor storage solutions.

For outdoor generators, engineers often specify that the fuel be stored in belly tanks under the generator. This can be a convenient, space-saving option, though there is a practical limit to the amount of fuel a belly tank can hold. If a tank is too large, stairs, platforms, or ladders may be required to gain access to service the generator. If a belly tank is too small, your operating time will be limited if it is your only method of storage. Discuss these considerations with your operations and maintenance staff.

In-building storage may be the best solution for smaller amounts of stored fuel. It also offers better protection from temperature fluctuations, weather events, and tampering. An example from Hurricane Katrina illustrates this point. As noted in “FAILURE OF INITIATIVE: Final Report of the Select Bipartisan Committee to Investigate the Preparation for and Response to Hurricane Katrina,” “Many of the parish EOCs [Emergency Operations Centers] and public safety facilities were wiped out or flooded. Jefferson Parish…was in better shape to respond because it had protected its EOC. Jefferson Parish Emergency Manager Dr. Walter Maestri explained the EOC was in a hardened facility—an old incinerator with cement walls—with the command center, living quarters, and emergency generator all on upper floors...[and] it was able to keep operating at some level.”

Fuel stored within your facility will require compliance with building codes, local and state codes, and building insurance requirements. Building and structure insurance policies often have strict requirements for the type and amount of fuel and storage equipment.

Compartmentation—While compliance with building codes and other mandatory requirements will result in a safe installation, there are other choices a user can make to improve the availability of the stored fuel. Compartmentation can help safeguard some or all of your reserve if a single localized event occurs, such as an explosion or fire. With compartmentation, the total amount of fuel is divided among multiple tanks. Fire- and blast-resistant separating-structures ensure there are barriers between tanks to prevent a local event from affecting the entire supply.

Compartmentation also supports the availability of backup fuel if one tank develops quality problems. Also, the use of multiple storage vessels helps limit cross-contamination should one tank be replenished with contaminated fuel.

Fuel quality

If you store fuel on-site, consider installing a fuel filtering or polishing system that will remove moisture and help prevent fuel degradation. Sediment that can build up in the bottom of storage tanks can be stirred up when fuel is delivered, often resulting in clogged filters and injectors, or decreased engine performance.

Fuel polishing and filtration helps minimize this buildup. Also consider fuel additives that will prolong fuel life, suspend contaminants so they can be trapped by the system filters, protect against corrosion, and prevent biological growths.

Temperature Considerations—Atmospheric temperatures can affect fuel quality. At approximately 30 F, fuel begins to cloud as the paraffin in the fuel starts to solidify. At 15 F, this solidification can turn into wax and can be severe enough to clog filters in the system.

Most providers offer winter blends designed to minimize clouding. If financial or logistical reasons necessitate the use of a summer blend fuel as you enter colder weather, other strategies to prevent this problem include additives, heat trace of piping, and immersion tank heaters.

Safety and security

Ensuring the safety of building occupants and the security of your fuel supply is fairly straightforward. During facility design, provide a rated room for fuel and generators stored in the building. Locate it near a loading dock or other low-traffic area, and provide controlled access. When using outdoor storage, critical facilities will likely have perimeter security in place to safeguard their fuel supply and generators. For less intensive facilities, secure walls or fencing around the fuel storage tanks is the most common protection strategy.

Planning ahead

It is impossible to predict every disaster scenario that could impact your fuel supply. But with early, careful planning, you can determine the amount, availability, storage, protection, and quality of a fuel supply that can support your operations through many of the most common natural catastrophes that occur in your region. A balanced strategy that considers costs and risks will ensure the success of your plan.

Fuel Polishing - Don't Just Take Our Word For It

- Friday, May 06, 2011

From Wiki Answers


WHAT IS FUEL POLISHING?

Fuel polishing is the process whereby diesel fuel is moved through filter media using a pump which operates independently of any other pumps on board a vessel. Fuel polishing is most commonly found in the marine industry, in particular yachting where vessels remain idle for extended periods of time.

The typical fuel polishing system consists of a pump/motor which is electrically powered, 12VDC, 24VDC, 110VAC or 240VAC. Again, these are the most typical. Also, the fuel polishing system consists of a fuel filter/water separator. One essential of a fuel polishing system is a vacuum gauge which will indicate the cleanliness status of the filter element found in the filter housing.

Fuel polishing systems must be capable of removing water, very fine particles (1-5 microns in size) and most importantly, moisture. There are numerous fuel filters which do an adequate job of removing water and particulates, however, unless they remove moisture, the microbes will continue to grow in the fuel tanks.

To be effective, fuel must be polished regularly. The entire volume of the fuel tanks must be circulated through the described filters four or five times a month. (MORE IS BETTER) Polishing fuel can be likened to polishing silverware, it takes many "passes" and it takes "frequent" passes in order to maintain the fuel (silverware) in tip top condition.

Once a year polishing is a thing of the past. With the newer diesel engines, there is a cleanliness standard which is far more stringent than that of days gone by. If you, the typical yachter, pleasure boater have experienced clogged filters, you know how aggravating that can be not to mention the danger of engines shut down in rough seas or critical situations.

Other fuel polishing scenarios include stationary generators, remotely located seasonally operated equipment such as agricultural pumps, oil field pumps etc. There are no doubt numerous applications, all of which share the same common denominator, idle fuel.

Google fuel polishing and you are sure to find several companies competing for their share of the market. A word of caution, be sure to address the MOISTURE question with whomever you contact. Also compare water removal capacities and size of particles removed. DON'T buy the cheapest, BUY THE BEST.

Typically smaller systems are cheaper and inadequate. Many systems offer the same inadequate filters that you may already have. More of the same is not the answer. Look at the customers' comments if they are available. Your peers are a good reference. Look at the company you are considering dealing with. Who are they doing business with.

Finally, fuel polishing is a long term investment. If you are a "long term" owner, then fuel polishing is for you. Simply stated, if you want your equipment to operate effectively for the long haul, invest in the "stuff" that will keep it in operating condition continuously.

Fuel Polishing question - Injector Failures

- Thursday, May 05, 2011
A common question we receive:
…“One of the worst problems we face with the reliability of our engines is the effect of bad fuel on the fuel injection system. This is true for most diesel engine manufacturers that make use of the latest technology in their electronically controlled engines. Although the manufacturer specifies water separators as primary fuel filtration (10 microns) and a 2 micron high efficiency secondary fuel filter system, we still have issues (even using the fuel they recommend) due to the quality of the fuel that is standard in our environment… We find that even with the best precaution methods, injectors have premature failures due to free water that bypasses all the systems in place. What else can we do to reduce system failures due to fuel?”
– Application Engineer

Answer:
We understand your problem and agree that today’s high-tech engine fuel systems have an Achilles Heel - Water.

Our fuel polishing systems, utilizing Separ Filters, remove up to 99.9% of all water and particulate. The best way to illustrate the need for and success of these systems is to showcase the following case. This photo below is from the U.S. Embassy in the UAE taken by Embassy staff.

Their problem was similar to yours in that they had fuel deliveries that were badly contaminated with water. This water destroyed several Cummins injection pumps and countless injectors. The picture (below) is the before and after just one (1) pass through our fuel polishing system. Since they started using the Portable Cart system, they have not had a single fuel-system related failure.
