石炭のテクノ-エコノミック有機精製法の開発
Document Type and Number:
Japanese Patent JP5523463
Kind Code:
B2
Abstract:
An improved organo-refining process to produce low ash clean coal from high ash coal, comprising: mixing coal, solvent and a co-solvent to produce a slurry; feeding the slurry to a reactor by pumping; extracting a coal-solvent mixture from the reactor; feeding the extracted mixture to a flasher unit; recovering about 30% of the solvent from the flashing unit; feeding the remaining heavy material to an evaporator; extracting about 60% of solvent from the evaporator; discharging the residue from the evaporator to a precipitator having water which produces a coal slurry; filtering the slurry in a rotary drum; collecting the super clean coal as a residue and feeding the filtrate into a distillation unit; and separating the water and the organic material in the filtrate to recover at least 7 to 8% of the remaining solvent.
