Abstract
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.
