Method of Application
Cargo tank cleaning following discharge of drying, semi-drying and non drying natural oils and fats. As soon as possible after the cargo has been discharged, the tanks should be flushed with cold water to prevent polymerisation and evaporation of the lighter oil fractions.
Whenever possible, the cleaning solution should be heated to 60-80°C. However, the polymerising nature of some natural oils may demand lower cleaning temperatures.
The most economical method of using "STANROSE® CLEAN CARE ALKALINE" is by direct injection followed by recirculation washing, using tank cleaning machines. If this method is not possible, hand spraying provides acceptable options. Refer to dosage table for dosage rates.
Cargo Residue | Hand Spray | Re-Circulation | Direct Injection | *Approx. re-circulation consumption, litres per 1000 m3 tank space
Fatty acids, fatty alcohols Fish oils | 100% | 3-5% | 2-4% | 180-300
Drying & Semi drying | 100% | 3-5% | 2-4% | 180-300
Vegetable oil | 50-100% | 2-4% | 1-3% | 120-240
Non drying vegetable oil | 50-100% | 2-4% | 1-3% | 120-240
*When using the re-circulation method, the tank to be cleaned is filled with water to a level that the heating coils are covered. As an average, this is approximately 0.6% of the volume of the tank. The figures mentioned in this column are the quantity of "STANROSE® CLEAN CARE ALKALINE" required to obtain the recommended solution strengths.
Storage and Handling
Keep away from heat, sparks and open flame. Ensure that the working area is well ventilated.
