ABSTRACT In order to process waste oil, and do this in an environmentally friendly manner, a procedure and a plant are used in which the old oil is pre-heated by distillation gases and then distilled by combustion of the distilled waste oil itself. The liquid and the solid residues are exposed to the flame that results from combustion of the distilled waste oil, whereas the gaseous residues are heated to a temperature above 1200°C in a long-term holding chamber that is configured as a flue-gas incinerator. In order to anneal the solid residues or burn the liquid residues, these are collected in the distillation chamber and passed through a rotary cylinder and a chute into the combustion chamber where they are appropriately annealed by the combustion flame. In contrast thereto, the gaseous residues are passed to a long- term holding chamber, this being a tubing system that is 75 m long or more. Heating rods or heating wires are installed in the individual tubes of the tubing system so that the waste gases can be brought deliberately and continuously to the required temperature and then cooled down once again. The correspondingly cooled flue gases that have been freed of injurious substances can then be released to the atmosphere. Using this procedure and the waste oil processing plant, it is possible to process waste oil, even when it is heavily contaminated, in an effective manner and either destroy the residues, which are of necessity formed, in an environmentally friendly manner or else so process them that they can be stored without posing any environmental hazard. (Figure 1).
