METHOD FOR IMPURITY REMOVAL FROM CARGO TANKS OF VESSELS THAT STORE AND TRANSPORT HYDROCARBONS

A process to remove impurities from a surface of a cargo tank of a vessel used to transport liquid hydrocarbons includes using an active chemical solution to dissolve at least a portion of the impurities or the matrix in which they are embedded deposited on the surface of the cargo tank. The process...

Zusammenfassung:	A process to remove impurities from a surface of a cargo tank of a vessel used to transport liquid hydrocarbons includes using an active chemical solution to dissolve at least a portion of the impurities or the matrix in which they are embedded deposited on the surface of the cargo tank. The process also includes allowing the active chemical solution to subsequently remove embedded impurities from the surface. Procédé visant à éliminer les impuretés d'une surface d'une citerne de charge d'un navire utilisé pour transporter des hydrocarbures liquides, ledit procédé comprenant l'utilisation d'une solution chimique active pour dissoudre au moins une partie des impuretés, ou de la matrice dans laquelle elles sont incorporées, déposées sur la surface de la citerne de charge. Le procédé comprend également l'étape consistant à permettre à la solution chimique active d'éliminer par la suite les impuretés incorporées de la surface.
