TANKCLEAN NEUTRAL can be used for the removal of vegetable oil, animal oil, fats and light mineral oils in aluminum and zinc silicate coated tanks. It is also being used as an after treatment agent in hydrocarbon-free cleaning operations where cleaning has been carried out with GP DEGREASER or SEACLEAN VOYAGE.
Directions for use
It is recommended to pre-wash the tanks with hot water at 50°C. For drying and semi-drying oils a pre-wash with cold water should be carried out immediately after discharge of cargo.
TANKCLEAN NEUTRAL is circulated in a 5% solution for a period of 2 – 6 hours. The temperature of the cleaning solution should be between 20 – 60°C. After circulation period rinse thoroughly with fresh water.
A chemical solution is prepared in an empty clean slop tank or one of the after tanks near the pump room. The solution is circulated via the automatic tank washing system pump and heater to the tank to be cleaned. The solution is returned to the solution tank via the stripping line. Usually it is not possible to recirculate the solution through the tank washing system heater (to maintain solution temperature during cleaning) without making a temporary connection between the solution tank and the tank washing pump. Capacities of solution tank, pipeline, connecting hoses, pumps, etc, should be calculated carefully to ensure sufficient solution is available to maintain continuous recirculation.
Depending on the size and condition of the tanks to be cleaned and the quantity of solution, normally 3 tanks can be cleaned with one solution. After which, a fresh solution should be made and heated before cleaning can continue.
Spray all the hot tank surfaces with undiluted TANKCLEAN NEUTRAL and let the product react for at least 30 min. Then rinse all tank surfaces with water at max. temperature 60°C for 45 minutes.
After cleaning and rinsing with hot fresh water at a max temperature of 60°C, hand-spray a 15% TANK CLEAN NEUTRAL solution in fresh water onto the hot tank surfaces and let it react for 30 minutes. Rinse thoroughly with hot, chloride-free water. If only fresh water is used, steam tank to remove any chlorides, which may cause delay in passing the chloride test for loading methanol, etc.
TANKCLEAN NEUTRAL is usually available in plastic cans of 25 l.
