PURPOSE: To make the easy sepn. of the oil-component and solid matter in oil-contg. sludge possible by making use of the partial combustion heat of the sludge.
CONSTITUTION: The oil storage tank sludge 5 is brought into contact with an oxygen-contg. gas 4 in the fluidized bed of a fluidized bed type thermal cracking furnace 1 to burn partially the sludge 5; at the same time, the oil- component in the sludge 5 is reformed to a low-viscosity oil by thermal cracking. The reformed oil obtd. in the above-mentioned manner is separated in a vapor form from the upper part of the fluidized bed to the outside of the system. The solid matter contained in the sludge 5 is separated from the lower part of the fluidized bed to the outside of the system. As a result, the easy sepn. of the oil-component and solid matter and further moisture in the sludge is made possible and the recovered oil obtd. in this stage has the low viscosity and permits easy transportation with a pump, etc., even without being mixed with a light oil or heavy oil.
