PURPOSE: To destroy high-molecular hydrocarbon adhered to solids and remove solids contained in mineral oil effectively by removing solids by a high gradient magnetic separator after agitating mineral oil at a high speed.
CONSTITUTION: First, mineral oil is agitated with a line mixer 1 at a high speed, and then mineral oil is fed into either of a high gradient magnetic separator 2 or 2', and solid contained in mineral oil is caught by a mesh layer constituted with magnetic small-gage wires in the separator 2. One of the separators 2 and 2' is regenerated, and liquid and gas for backwashing are flowed from containers 4 and 5 simultaneously in the direction reverse to the direction when treated, solids caught by the mesh layer being removed by the vibration of gas bubbling. Liquid and gas are separated by a separator 6. Treatment and regeneration are carried out alternatively.
