Cleaning of tanks

Pre-wash before cleaning with FALCHEM NEUTRAL HCF, it is recommended to pre-wash with hot water at 50ºC. for drying and semi drying oils a pre-wash with cold water should be carried out
immediately after discharge of cargo to retard oxidation and hardening of oil residues.

Recirculation method

A chemical solution is prepared in an empty slop tank or one of the after tanks near the pump room, circulated via automatic tank washing system pump and heater to the tank to be cleaned. Where from the solution is returned to the chemical solution tank via the stripping line. Usually it is not possible to recalculate the chemical solution through the tank washing system heater (to maintain solution temperature) without making a temporary connection between the chemical solution tank, pipeline and pumps ect should be calculated carefully to ensure sufficient volumetric quantity for a continuous recirculation. Depending on size and condition of tanks to be cleaned and quantity of chemical solution, a drawback in this method is that usually only 3 tanks can be cleaned with one solution after which a fresh solution should be made and heated before cleaning can continue. Depending on the degree of contamination FALCHEM NEUTRAL HCF is circulated as a 5% solution for a period of 2 – 6 hours. The water temperature should be approx. 20 – 60ºC. after the circulation period rinse thoroughly with water.
