    • PROBLEM TO BE SOLVED: To provide a method for effectively removing a colloidal metal sulfide produced from a metal carbonyl compound from a washing effluent containing methanol generated when an industrial gas is washed with methanol at low temperatures. SOLUTION: The method and apparatus therefor for removing the colloidal metal sulfide produced from the metal carbonyl compound from the washing effluent containing the methanol generated when the industrial gas is washed with the methanol at low temperatures is characterized in that the washing effluent is introduced into a settlement tank where the colloidal metal sulfide is coagulated to be particles with a larger diameter by heating, and that next the washing effluent is introduced into a separation column, from which the particles of the metal sulfide with the larger diameter are discharged with a bottom product.
