Title: Treatment of heavy oil based combustion ash
Inventor: NOZAKI KENJI
IPC: B01D11/02
Filed: 1999-07-15
Abstract: PROBLEM TO BE SOLVED: To effectively separate and recover valuable metals such as vanadium or nickel from heavy oil based combustion ash by adjusting slurry of the heavy oil based combustion ash to be neutral or alkaline at an ordinary temperature, adding an oxidizing agent to the slurry under this liquid characteristic and carrying out alkali-dissolving while oxidizing vanadium or the like. SOLUTION: When heavy oil based combustion ash generated when the heavy oil based fuel, e.g. tar based fuel, petroleum cokes and petroleum pitch, etc., is burned at a thermal power plant or the like is treated, first an alkaline liquid is added to the heavy oil based combustion ash at an ordinary temperature to form a slurry having a liquid characteristic adjusted to be neutral or alkaline. Then an oxidizing agent which reacts in a neutral or alkaline state, e.g. hydrogen peroxide, is added under this liquid characteristic to carry out alkali-dissolving of metal contained in the slurry, e.g. vanadium, nickel, etc. Thereby, vanadium or nickel can be efficiently dissolved from the heavy oil based combustion ash with a simple operation. Oxidative gas as a material for supporting oxidation, e.g. oxygen, air, etc., can be introduced during stirring.
