Abstract
A method for producing refined-coal has steps of (A) heating a mixture including moisture-containing coal and oil, to dehydrate the coal; (B) removing, in a first mist separator having plural baffle plates disposed in parallel, fine particles accompanying vapor generated by the dehydration step and adhered to the surface of the a first mist separator by spraying a liquid at a temperature of 50 ° C. or above and 150 ° C. or below in the first mist separator, which temperature is lower than a temperature to which the mixture is heated in step (A), wherein the sprayed liquid includes an oil component; and (C) compressing the vapor to obtain high-temperature vapor. In the step (B), the vapor is made to sequentially pass through the first mist separator and a second mist separator of a mesh type, while spraying liquid onto the first mist separator through which the vapor passes firstly.
