A heavy duty solvent emulsifier, containing petroleum solvents, emulsifiers, and surfactants, Tank cleaner it is used as a tank cleaner or for general degreasing.
Directions for use and Dose Rates .
Tank cleaner is recommended for local cleaning and degreasing and may be applied by brush, hand spray, immersion, soaking or any other conventional means.Apply undiluted over soiled area and allow a contact time of between 15-30 minutes before rinsing off with water.
Soak Method
Put parts to be cleaned into a bath of Tank cleaner, undiluted for heavy soil, for medium to light soiling use a solution of 10-30% Tank cleaner in water. parts should be soaked for at least 30 minutes before washing off with water.
Spray Method
Spray Tank cleaner undiluted over all soiled areas. Allow time for Tank cleaner to act, between 15 and 30 minutes, then rinse off by water hose. For stubborn deposits, agitation by scrubbing will assist the cleaning operation.
Cargo Tank cleaning after Mineral oils.
Direct injection method
use with Tank cleaning machines is recommended .
dose rate should be between0.1 and 2.0% i.e. one to twenty litres per ton wash water .Best results are obtained when water is heated to a temperature between 65ºC and 80°ْC slops should be constantly stripped from the tank and transferred to a holding tank or pumped ashore to slop tanks.
Recirculation method
Used with Tank cleaning machines. it is recommended to use a solution strength of 0.5-3% (i.e.5 to 30 litres per ton wash water) mixed in the tank to be cleaned. The washing solution is usually 5-10 % of the tank capacity.Best results are obtained when water is heated to a temperature between 65 ºC and 80 ºC . Dose rate and results will vary depending on amount of contamination and number of tanks to be cleaned with this solution .After cleaning, slop water should be pumped ashore or to ship's slop tanks.
Spot cleaning
Tank cleaner can be sprayed neat onto surfaces and left for at least 30 minutes. Using tank washing machines or high pressure hoses, wash down the tank surfaces with hot water between 60°C and 80 °C. keep stripping tank slops and transfer to holding tank/slop tank.
Cleaning of the oil side of lube oil Heat Exchangers
Cleaning is best achieved by the recirculation method using a heated 20 % solution of Tank cleaner .
1)Disconnect the heat exchanger s oil inlet and outlet, drain off any remaining oil.
2)Connect the discharge side of a portable pump to the lower heat exchanger connection and the suction side of the pump to the bottom outlet of a 200 litre drum
3)Complete the circuit by connecting the upper connection on the heat exchanger to the top of the drum.
4)Add the required solution to the drum and arrange an immersion heater or live within the drum to raise the temperature of the cleaning solution to 65-75ºC and maintain the temperature throughout the cleaning operation. if it is not possible to heat, the operation will need to be extended.
5)Use the pump to maintain circulation for 12 to 15 hours. when the cleaning is completed, disconnect the lower heat exchanger connection and drain out the cleaning solution.
6)Connect a fresh water supply to the upper heat exchanger connection, and rinse until the water runs clean from the lower connection.
7)When rinsing is complete, disconnect the water supply and thoroughly drain and dry the heat exchanger.
