| titleOfInvention | Process for the recovery of cobalt oxide from the residues in the dmt process |
| abstract | The present invention relates to a method for recovering concentrated cobalt oxide by treating a cobalt tar generated as a by-product in a process for producing dimethyl terephthalate (DMT) by a low-temperature thermal reaction and a magnetic separation process, wherein the cobalt tar is pulverized To obtain granular cobalt tar; A primary heat reaction step of thermally reacting the granular cobalt tar obtained in the pulverizing step with the primary heat reaction furnace at a temperature of 260 ° C or lower to evaporate and separate the DMT component contained therein to obtain a primary concentrated cobalt ingot; Pulverizing the primary concentrated cobalt ingot obtained in the primary thermal reaction step to a granular grain of not more than 5 mm and selectively concentrating the tar and tar-containing cobalt contained in the primary concentrated cobalt ingot under strong magnetic field to obtain tar cobalt; The cobalt oxide was recovered from the residues of the DMT production process as a second thermal reaction step in which tar cobalt obtained in the magnetic separation step was thermally reacted at 260 ° C or less in a secondary thermal reaction furnace to evaporate and separate the contained DMT components to obtain concentrated cobalt do. As a result, cobalt tar, which is a residue of the DMT manufacturing process, is concentrated and recovered by low temperature thermal reaction and strong magnetic field lines without conventional incineration treatment or wet chemical treatment, The emission of pollutants hardly occurs. |
