Date May 16, 1991.For the processing of waste oil, i.e. environmentally safe processing, a process and installation are used whereby the waste oil is preheated with the distillation gases and is then distilled itself by burning the distilled waste oil. The liquid and solid residues are exposed to the flame produced by the combustion of the distilled waste oil, while the gaseous residues are heated to over 1,200 DEG C. in a long-hold chamber constructed as a fume incinerator. In order to calcine the solid or burn the liquid residues, they are collected in the distillation chamber and transported via a rotating cylinder and a chute into the combustion chamber where they are then correspondingly calcined by the burner flame. In contrast, the gaseous residues are fed to a long-hold chamber, whereby the latter is a pipe system with a length of 75 m or more. Heating rods or heating wires are inserted into the individual pipes of the pipes system, so that the waste gases are brought specifically and continuously to the required temperature and are then cooled again. The flue gases cooled in this way and freed from noxious substances may then be released into the atmosphere. By using this process and the waste oil processing installation, it is possible to effectively process even waste oils heavily contaminated with noxious substances and to either destroy the inevitable residues in an environmentally safe way or to process them in such a way that they may be disposed of in an environmentally safe manner.
