1. Wide range of different products from very light and thin transformer or spindle oils to heavy and dark cylinder or geaoils.
2. Different carriage temperatures and heating requirements depending on the viscosity.
3. The viscosity will decrease with increasing temperature.
4. High/No flash point .
5. Butter worth the tanks 1-1, 5 hours with hot seawater or freshwater (70-80°C).
6. Prepare the following cleaning solution in freshwater or seawater: 0.4 % RXSOL CTC VOLC Butter worth the tank 1,5 hours by recirculation with a temperature of approx 70°C. The necessary temperature can be achieved/ maintained by means of heating coils, or going via the Butter worth heater. Depending on the amount of cargo residues the solution can be used for 1 to 3 tanks.
- Butter worth the tank for 0, 5 hours with hot fresh water.
- Ventilate, mop and dry the tank
- Instead of recirculation cleaning the RXSOL CTC-VOLC can as well injected into the Butter worth system (see cleaning method 3). The use of the RXSOL CTC- VOLC is not recommended for cleaning of Fuel oils / Bunker oils These products have to be pre-cleaned with water of a warm to moderate temperature followed by a recirculation cleaning with gas oil. To reduce the amount of slops the following cleaning procedure is recommended:
7. Pre-cleaning (see drawing method 4, next page) .
- Depending on the tank size and height fill the necessary amount of freshwater or seawater into the service tank .
- Butter worth all tanks to be cleaned 1-1,5 hour using the water from the service tank .
- Heat the wate r by means of heating coils, cargo heat exchanger or going via the Butter worth heater.
- The pre-cleaning temperature should be between 70 and 80°C.
- Pump the waste water from the tanks to be cleaned back to service tank (overtop).
8. Solution-cleaning (see drawing method 4, next page) .
- Depending of tank size and height fill the necessary amount of freshwater or seawater into the service tank.
- Butter worth all tanks to be cleaned 1-1, 5 hour using the solution from the service tank .
- Heat the Solution by means of heating coils, cargo heat exchanger or going via the Butter worth heater.
- The cleaning temperature should be approx 70°C .
- Pump the used solution from the tanks to be cleaned back to service tank (over top).
