ABSTRACT:
An apparatus and process adapted to clean oil contaminated vessels which uses a closed fluidized system through which fluidized sludge is recirculated to be sprayed under pressure on interior walls of the vessel. Emulsifying agents are added to the vessel to initially form a pool of fluidized sludge in the vessel which is then conveyed to a tank and from the tank conveyed to a high pressure spray where it is sprayed onto the walls to fluidize more sludge.
