PROCESS FOR RECOVERING METALS FROM A STREAM RICH IN HYDROCARBONS AND CARBONACEOUS RESIDUES |
摘要 |
A process for recovering metals from a stream rich in hydrocarbons and carbonaceous residues by means of a treatment section, characterized in that it comprises the following steps: sending said stream to a primary treatment, effected in one or more steps, wherein said stream is treated in the presence of a fluxant agent in a suitable apparatus, at a temperature ranging from 80 to 180°C, preferably from 100 to 160°C, and subjected to liquid/solid separation in order to obtain a clarified product essentially consisting of liquids and a cake (oilcake); possibly subjecting the separated cake to drying, in order to remove the hydrocarbon component having a boiling point lower than a temperature ranging from 300 to 350°C from the cake; sending the cake, possibly dried, to a secondary thermal treatment comprising: a flameless pyrolysis of the cake effected between 400 and 800°C, preferably between 500 and 670°C; an oxidation of the pyrolysis residue effected in an oxidizing environment and at temperatures ranging from 400 to 800°C, preferably from 500 to 700°C. |
