Dosage

RXSOL 666 is covering 10-12 squire meter are when spraying directly. It is advised to use a solution of 2-5% wash water mixed in the tank to be cleaned. Dose rates and results will vary depending on contamination, the temperature of the cleaning solution, and number of tanks to be cleaned with the solution.

Spot  cleaning

RXSOL 666 can be sprayed neat onto tank surfaces to be cleaned. The contact time should be at least 30 minutes. Bulkheads/walls can be washed down by use of tank washing machines or high pressure cleaning machines. The best result is achieved with warm water. Slops should be constantly stripped from the tank and transferred to a holding tank or pumped ashore to slop tanks.

Rock and Roll method (Cargo Tank)

1.    Cleaning of double bottom tanks during voyages.
2.    Flush tank with sea water, stripping constantly.
3.    After flushing, ensure all suction and discharge valves in the engine room are closed.
4.    Dose tank with Rxsol 666 through the sounding pipe or manhole between 0.5 - 1 litre per ton of water, for   75-80% of capacity of tank to be cleaned.
5.    Fill tank to 25% capacity with sea water, raise the temperature up to 60°C and maintain this for 24 hours.
6.    Discharge and strip tank, flush with sea water, stripping continuously for 2 hours.
To gas-free, fill tank with sea water to overflow through vents and sounding pipes, discharge and strip completely.

Pipeline Cleaning

1. Isolate Pipelines: Check blockage, pipeline material, and pressure limits.
2. Remove Bulk Sludge: Use pigging, vacuum removal, or sectional cleaning where feasible.
3. Compatibility Test: Test RXSOL 666 HD on actual HFO sludge.
4. Pilot Trial: Determine dosage, contact time, and circulation conditions on a small section.
5. Chemical Circulation: Circulate through a closed-loop system with pressure monitoring.
6. Recover & Flush: Collect spent cleaner and sludge, flush with a compatible medium, and verify flow restoration before recommissioning.
