Styrene Monomer (Cleaning Procedure)

During loading, transport, discharge and tank cleaning avoid any heat and heated cargoes in adjacent tanks (risk of polymerisation). Use a new solution of RXSOL CTC-VOLC only for removal of the smell (final touch).

1.   Butterworth the tank 1, 5 hours with cold sea water or freshwater
    
2.   Prepare the following solution in the tank to be cleaned: 5 m3 fresh
     water, with a temperature of 30°C. 1 pail of CTC-Cleaner-VLC
     (0.4%)Butterworth the tank one hour by recirculation (T: 30°C).
    
3.   Rinse the tank 15 minutes with fresh water
    
4.   Ventilate, Mop and Dry the tank. Instead of recirculation cleaning as
     per
    
5.  the RXSOL CTC-VOLC can be also injected into the Butterworth
    system:
    
6.  AButterworth the tank 1, 5 hours with cold seawater or freshwater.
    
7.  BButterworth the tank 1 hour with seawater or freshwater of a 
    moderate temperature 
    (approx 50°C) and inject the RXSOL CTC-VOLC (see method 3).
    
8.  B should be carried out only for the removal of smell (No residues of
    Styrene present)
