Nowadays, the cleaning of petroleum
storage tanks becomes a necessity for
a number of reasons, e.g.
- to prepare a tank for a different
   product;
- to prevent product comtamination;
- to prepare for repairs or modifications;

compounds in addition to the flammable
gases associated with the sludge in the
petroleum tanks.
