The present invention is a method for treating hydrocarbon-containing waste, especially rolling scale slurry and / or grinding slurry, wherein the waste is heated in a drying device by indirect supply of heat, It relates to a process which is preferably displaced and the hydrocarbons are removed, where appropriate, together with other volatile components, in particular H 2 O. In this treatment, in a low-temperature drying device, the hydrocarbons are separated by a specific method, and the hydrocarbons are affected by a chemical that affects the decomposition of the less volatile hydrocarbons into the more volatile hydrocarbons. Separation by means of kinetic and / or radiative means, preferably the decomposition of high molecular weight hydrocarbons into low molecular weight hydrocarbons, said hydrocarbons, if appropriate with other volatile components, in particular with H 2 O. In particular, the liquid is at least partially discharged from the vessel by suction. The invention also relates to an apparatus for treating a waste containing hydrocarbons. |
