REFINED-COAL PRODUCTION METHOD, AND REFINED-COAL PRODUCTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/077027
Kind Code:
A1
Abstract:
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.
