Idrabel Italy provides environmental services (oil tank cleaning and VOC emissions and explosiveness reduction) employing innovative automated systems. Idrabel operates in the national and international market and has recently obtained an important contract for specialized works in a tank farm in Central Africa.
The works represents an important challenge for Idrabel because of the characteristic and difficult to deal with traditional technologies. The subject crude oil tank (capacity 90,000mc) presents noticeable problems outlined in the following points:
- The floating roof is distorted, rolled up and partially sunk
- The roof legs remain in position and cannot be repositioned
- The roof is not in shape for use under any condition
- The tank contains a noticeable quantity of crude and sludge
For the above mentioned reasons, traditional automatic / mechanical work techniques using devices installed on the roof are not applicable. In addition, manual systems present safety problems which prevent their application.
Idrabel will operate on the tank employing its own automated / mechanical cleaning method, called BioRecOil Process (already used in more than a hundred tanks of large dimensions).
The unique “non-entry method” (that minimizes the unfitness of the tank) is flexibile and Idrabel’s know-how allows us to adapt the procedures to tanks with specific problems.
The BioRecOil Process (Biological Recovery of Oil) is based on the combined action of hydrodynamic telescopic modules installed on the tank manholes. The action of the circulation is provided by powerful pumps and biotechnological products (Biosurfactants).
