ADERCO L 1050 – LUBRICITY IMPROVEMENT ADDITIVE

Poor lubricity is an inherent property associated with certain light density and low viscosity fuels – for example naphtha, kerosene and gas condensates. These type fuels provide little or no lubrication to metal surfaces and as a result, so that critical components such as fuel pumps are likely to experience serious wear and premature failure. Furthermore the ignition delay in the boiler can increase the risk of a boiler explosion on board of the vessels.

ADERCO L 1050 to control corrosion in gas condensates is a lubricity improvement additive that has been specially developed to address wear problems in fuel pumps and to alleviate excessive operational and maintenance issues when burning low lubricity fuels.

Unlike earlier-generation products that are available on the market, ADERCO L 1050 has been specifically developed to address the unique technical requirements of the marine industry. This additive also overcomes certain undesirable properties associated with earlier products, such as solubility, stability and incompatibility. Taking all this into consideration during the development stage this has resulted in the following product features and benefits:

• Highly concentrated product • Helps to protect wear on fuel pumps and injectors • High Flash point - no extra storage required • Easy to transport – no airfreight restrictions • Considered a non-dangerous, non-hazardous product • Excellent mixing and compatibility with gas oil • No tendency to form troublesome gum deposits • No interaction with other fuel additives

AVERAGE DOSAGE: 1 litre per 30 tonnes of fuel. DOSAGE: Aderco L 1050 ranges from 1 litre per 10 tonnes up to 40 tonnes Why is the dosage rate not fixed? ISO has created a specification for the fuel. According to the results on measurement from HFFR, the dosage of the lubricity improver can be calculated. In practical terms, therefore, the scartest and the dosage has to be calculated accordingly after each bunkering! A new product assisting to deal with the official Emission Requirements The limits applicable in Sulphur Emission Control Areas (SECAs) will be reduced to 1.0 % effective from 1st July 2010 (from the current 1.5 %; being further reduced to 0.10 % effective from 1st January 2015.). The last change which will have immediate effects from 1st January 2010, is the reduction to 0.10 % of sulphur for those vessels operating in ports of the SECAs area. A new grade of distillate fuel is born. The DMZ is a new grade of distillate fuel. The difference between DMX – DMA and DMZ is the minimum viscosity of 3.000 mm²/S @40°C This DMZ is made to respect the minimum requirements of engine builders at the level of viscosity in Gas Oil. Do not confound viscosity and lubricity which are total different items without any link between the one and the other. For exemple: You can have a high viscosity with a low grade of lubricity and the inverse is possible too: a low viscosity and a high grade of lubricity The use of ADERCO L 1050 will help you highering the level of lubricity The both following diagrams are showing the results

How Diesel Fuel Is Evaluated For Lubricating Ability: Diesel fuel and other fluids are tested for lubricating ability using a device called a “High Frequency Reciprocating Rig” or HFRR. The HFRR is currently the internationally accepted, standardized method ISO 12156-1

to evaluate fluids for lubricating ability. It uses a ball bearing that reciprocates or moves back and forth on a metal surface at a very high frequency during 90 minutes. The machine does this while the ball bearing and metal surface are immersed in the test fluid (in this case, treated diesel fuel). At the end of the test the ball bearing is examined under a microscope and the “wear scar” on the ball bearing is measured in microns. The larger the wear scar, the poorer the lubricating ability of the fluid. The independent lab runs every sample twice and averages the size of the wear scar.

INSTRUCTION SHEET

ADERCO L 1050 LUBRICITY IMPROVER

1. ADERCO L 1050 CAN HELP YOU

IMPROVE THE LUBRICATING ABILITY OF ULTRA LOW SULPHUR MGO. IT PREVENTS EXCESSIVE WEAR ON FUEL PUMPS AND INJECTION SYSTEM.

2. DOSAGE INSTRUCTIONS

1 LITER ADERCO L 1050 PER 30 TONS OF MGO. TO BE POURED IN THE STORAGE TANKS THROUGH THE FEEDLINE, VENT-PIPES OR THE SOUNDING-PIPE BEFORE BUNKERING. IF USING A SOUNDING PIPE, BE SURE THAT THE ADERCO L 1050 HAS BEEN POURED INTO THE TANK. COMPRESSED AIR CAN BE USED TO BLOW IT INSIDE. IF THE TANK IS ALREADY FILLED, POUR INTO THE TANK AND CIRCULATE 5 TIMES THE QUANTITY BY USING A CIRCULATION PUMP.

AS SOON THE ADERCO L 1050 IS INTRODUCED INTO THE FUEL, LUBRICITY WILL IMPROVE.

DESCRIPTION

Government regulations concerning emissions have forced refineries to modify certain properties of diesel fuel. The result is that today’s diesel fuel has reduced lubricity. ADERCO L 1050 is an additive specially formulated to improve lubricity in ultra low sulfur diesel fuels. This lubricity is essential for proper operation of injection pumps and injectors in diesel engines.

DOSAGE The normal dosage for 1 liter of ADERCO L 1050 varies between 10,000 to 50,000 litres of fuel depending on the severity of the base fuel. Some diesel fuel can demand higher dosage of additive. Please contact your ADERCO representative for specific recommendations. Average dosage: 1 litre per 30 tonnes of fuel.

BLENDING

Simply add the required quantity of ADERCO L 1050 to the diesel tank before fuelling. The movements of the vessel will be sufficient to adequately mix the additive.
