摘要： The purpose of the present invention is to provide a refined-coal production method and a refined-coal production device, which exhibit excellent operability, and with which droplets accompanying steam generated when dehydrating moisture-containing coal is efficiently removed. This refined-coal production method is provided with: a step (A) in which a mixture including moisture-containing coal and oil is heated to dehydrate the coal; a step (B) in which droplets accompanying steam generated by performing dehydration are removed; and a step (C) in which steam, having had the droplets removed therefrom, is compressed to obtain high-temperature steam. The refined-coal production method is characterized in that, in step (B), the steam is sequentially passed through one or a plurality of mist separators, and removal of the droplets is performed while liquid is being sprayed onto a first mist separator through which the steam passes firstly.

摘要： Provided is an ash-free coal production method that can produce an ash-free coal efficiently with a higher solvent recovery rate. The ash-free coal production method includes an extraction step of mixing coal with a solvent to give a slurry and heating the slurry to extract a solvent-soluble coal component; a separation step of separating a solution containing the coal component from the slurry containing the extracted coal component; and an ash-free coal obtaining step of separating and recovering the solvent from the separated solution to give an ash-free coal. The ash-free coal obtaining step includes a pressure-reducing substep of reducing a pressure to a level lower than the solvent vapor pressure to evaporatively separate the solvent from the solution to thereby give a solid ash-free coal; and a heating substep of heating the solid ash-free coal to evaporatively separate a residual solvent from the ash-free coal.

摘要： A method for separating solvent-containing water, which is generated in the process for producing an ashless coal, into a solvent and water readily without using any adsorbent or the like (a solvent separation method). The solvent separation method comprises: a solvent-containing water supply step of supplying the solvent-containing water into a pressure vessel for solvent separation purposes; and a temperature retention step of retaining the temperature of the solvent-containing water that has been supplied into the pressure vessel for solvent separation purposes at a predetermined temperature (e.g., 100 to 180 DEG C. inclusive). In the pressure vessel for solvent separation purposes, water in the liquid form moves downward and the solvent moves upward due to the difference between the density of water and the density of the solvent at the predetermined temperature. In this manner, the solvent-containing water can be separated into the solvent and water.

摘要： A method and apparatus that deterioration of the flow state of a coal/kerosene slurry while preventing the damage caused by overloading to thereby achieve excellent solid-liquid separation performance. In a solid-liquid separation supplying a dehydrated coal/kerosene slurry to a decanter-type centrifugal separator to separate the coal/kerosene slurry into a solid fraction and a liquid fraction, an opening degree target value is determined on the basis of the difference between a target value and an actually measured value of a torque that acts on a screw conveyor of the decanter-type centrifugal separator, and the opening degree of a flow volume control valve, which is arranged in the middle of a supply line for supplying the coal/kerosene slurry into the decanter-type centrifugal separator, is adjusted to the opening degree target value.

摘要： Provided is an ash-free coal production method without the need to once re-liquefy and form an ash-free coal. The ash-free coal production method includes an extraction step of mixing coal with a solvent to prepare a slurry and heating the slurry to extract a solvent-soluble coal component; a separation step of separating a solution containing the solvent-soluble coal component from the slurry obtained from the extraction step; an ash-free coal obtaining step of evaporatively separating the solvent from the solution separated in the separation step to obtain an ash-free coal. The ash-free coal obtaining step in the production method is performed so that the solvent is evaporatively separated from the solution to give a liquid ash-free coal, and the liquid ash-free coal is brought into contact with a solidifier (e.g., water) to solidify into a predetermined shape.
