FOT - Fuel Oil Treatment

Description

FOT fuel oil treatment is a highly effective blend of self-dispersing solvents, surfactants, detergents and emulsifying agents. It has been designed to overcome the numerous difficulties in handling and burning heavy residual fuels.

Application and Use

As a fuel oil conditioner, FOT fuel oil treatment helps counteract the burden placed on the fuel transfer system by moisture, heavy hydrocarbons, excessive sludge and carbon deposits. In emulsifying moisture and dispersing sludge, FOT treatment reduces maintenance, contributes to better atomization for more complete combustion and increases the utilization of available heat units of bunkers by liquefying otherwise unburnable sludge masses which would precipitate out.

As a solvent, FOT treatment will assure quicker, easier and more thorough cleaning of carbonaceous deposits, bakedon sludge, varnish, gummy deposits and waxy residue from the wide varieties of marine petroleum products.

Versatility is its greatest virtue. A list of some of FOT treatment's numerous applications include:

• On-steam fuel conditioning

• Fuel tank sludge removal • Solvent cleaner:

- fuel oil heaters and strainers

- lube oil filters and coolers

- oil guns and burner tips

- air register units

- fuel pumps

Fuel Oil Conditioner

As an on-stream treatment, FOT treatment is added to the fuel tanks to combat fuel handling problems from tank bottom to burner tip. Its specially formulated detergents and emulsifiers enable the fuel to become a more stable, homogeneous fluid. Combustion is enhanced by improved atomization and flame stability. This results in safer operations, cleaner firesides and maximum heat output. The homogenizing action of FOT treatment disperses sludge and suspends heavy hydrocarbons. This reduces deposition of fuel particles, which means less frequent cleaning of double bottoms, fuel oil preheaters, strainers and burner tips. Fuel losses associated with these deposits are minimized, meaning higher yields from bunkers purchased.

Solvent Applications

As a solvent, there are two main areas of maintenance where FOT fuel oil treatment is especially beneficial:

1. Cleaning of burner assemblies, fuel oil heaters and strainers, and lube oil coolers. FT-PD-4 Rev .10

2. Removing heavy sludge deposits in double bottom and deep tanks.

1. Cleaning Burner Assemblies:

Removing carbon deposits maintains fuel handling and burner equipment in proper condition to deliver maximum performance. Use of FOTTM treatment by the soaking or circulating method reduces cleaning time and eliminates damage from scraping. It is convenient since oil guns and air register units are cleaned fully assembled. FOT treatment will also clear oil passages of deposits in the burner barrel which are normally inaccessible for manual cleaning. This helps keep burner tips from plugging since barrel deposits may break away during operation.

The following procedures are recommended when cleaning units fully assembled:

• The size of the container should be such that the unit is at least three quarters submerged in FOT treatment with the lower end 7-10 cm above the bottom of the container to allow for accumulation of carbon sludge.

• Oil guns that have just been removed from operation should be hung up for a few minutes to drain off excess oil.

• Vertically submerge equipment in FOT treatment for a minimum of two (2) hours. Since FOT treatment has no harmful effect on metal, soak for as long as desired or until equipment is needed.

• When required for use, remove assembly from container, allowing FOT treatment to drain off for a few seconds. In the engine room, FOT fuel treatment may be used again and again. When its effectiveness as a solvent has been exhausted, the oil material may be placed in settlers or reclaimed oil tank to keep tanks clean and free of sludge.

2. As a Sludge Remover:

Diluting FOT treatment with a commercial solvent such as kerosene (3 parts kerosene: 1 part FOT treatment) yields a powerful and inexpensive solution that performs admirably in removing heavy sludge deposits from double bottoms and deep tanks. Dilution helps carry FOT treatment's active ingredients over a greater area, bringing about more complete contact with the sludge. Cleaning procedures for quickly eliminating deposits caused by ballasting of fuel tanks include the combination of heat, motion, and FOT treatment:

• If fuel tanks are carrying ballast, it is always wise to heat about half the ballast water before completely stripping the tank.

• Any remaining sludge can be uniformly suspended throughout the fuel oil by introducing the FOT treatment solution into the tanks prior to bunkering. The agitation during bunkering will bring about more thorough distribution of the treatment.

• Should excessively heavy deposits of sludge exist in the fuel tanks, pump fuel down to the sludge level, and add the FOT treatment solution to the tank at a rate of 1 liter per 35 liters of sludge. Keeping heat on, circulate the treated sludge back and forth between the sludged tanks and another slack tank which also has heat on. Continue recirculating until the sludge becomes a uniform fluid. Add FOT treatment to new fuel taken onboard at the recommended dosage rate prior to bunkering. Agitation during bunkering will assist in providing thorough distribution of the broken-up sludge particles and FOT treatment. Continue recirculating between tanks until the sludge is completely dispersed into the body of the fuel. The petroleum detergent incorporated in FOT treatment will break down the resistance of the sludge to mix with fresh fuel by chemically conditioning the fuel oil surface tension.
