| titleOfInvention | Processing technology of waste mineral oil dregs |
| abstract | The invention discloses a processing technology of waste mineral oil residues, which comprises the following steps: putting the waste mineral oil residues into a reaction kettle, adding an organic solvent, and fully stirring; then the mixed liquid is filtered and placed on a dryer to be dried to obtain dry oil residue; then putting the dried oil residue into a crusher; then, the oil residue powder is blown through two layers of channels provided with electromagnets and used for removing metal impurities in the oil residue; then, putting the grease powder after the metal impurities are removed and caustic alkali into a stirrer according to the weight ratio of 5:1 for fully mixing; then placing the mixed powder in a closed heating furnace for heating, finally soaking the reactant in a dilute acid solution, then washing with water for multiple times, and drying to obtain asphalt; the invention utilizes the organic solvent to remove the redundant oil in the oil residue, removes the oil residue through the electromagnet, and removes the sulfur in the oil residue through the reaction with the caustic alkali, thereby obtaining the purer asphalt and facilitating the subsequent utilization. |
