Abstract
A method for producing an ashless coal which includes a slurry preparation step, an extraction step, a separation step, an ashless coal acquirement step, and a by-product acquirement step. The separation step is conducted under the state of being pressurized to a pressure equal to or higher than a vapor pressure of the solvent. In the by-product acquirement step, the solvent is evaporated and separated from the solid content-concentrated slurry by spraying the solid content-concentrated slurry into a flash tank in which a pressure is set to lower than a saturation pressure of the solid content-concentrated slurry from a spray nozzle while maintaining a pressure of the solid content-concentrated slurry in a nozzle orifice of the spray nozzle at a level equal to or higher than the vapor pressure of the solvent.
