Abstract

The sludge collecting in a floating roof type oil storage tank is disposed of by inserting a compressed liquid spurting device in a straightened state into the tank through an orifice in the floating roof, feeding compressed liquid to the spurting device, causing the spurting nozzle of the device to be swung about the device proper and, at the same time, releasing the compressed liquid against the sludge inside the tank thereby causing the sludge to be disintegrated and fludized by the force of the compressed liquid, and allowing the fludized sludge to be drawn into a reservoir whose interior is under negative pressure.
