The dilution rate varies depending on the contamination rate of the surface to be cleaned. In cleaning of vegetable or animal oil, it is advised to start cleaning as soon as possible after discharging the cargo. Particularly in the cleaning of dry vegetable oils and animal oils, prewashing with hot water should not be performed (prewashing with cold water should be done in order to prevent saponification reaction). If sea water is used during the rinsing stage after cleaning, it may cause a risk of corrosion, It is recommended to use fresh water instead of sea water for rinsing after cleaning.
1 – CIRCULATION METHOD
3-5% solution is prepared for high pollution and 2-3% solution is prepared for less pollution. After the solution temperature is raised to 60-80°C, it is circulated for 3-4 hours. Same solution can be used for 3-4 tanks depending on dirtiness degree. After cleaning, surface should be rinsed with plenty of water.
2 – INJECTION METHOD
Chemical solution prepared with 2-3% ratio, is transferred into Butterworths inside the tank through injection method. Water temperature should be 60-80°C . Washing should continue for 2-3 hours and after cleaning, rinsing operation should be carried out with fresh water.
3 – SPOT CLEANING
It is recommended to use the chemical product in concentrated form for the cleaning of stubborn oils (fish oil, palm oil etc.) It is possible to dilute the product with ½ to 1 / ratio for the cleaning of other pollution (vegetable and animal oils). Prepared solution is brought to 55-60°C temperature and injected to the surface. The solution should be left on the surface for a maximum of 30 minutes. The solution on the surface must not be allowed to dry in order to avoid saponification reaction during waiting. Rinse with water with a temperature similar to the solution after cleaning.
