Title (EN) TREATMENT OF LOW RANK COALS
(FR) TRAITEMENT DE CHARBON DE RANG BAS
Abstract:
(EN) A process for treating coal in which coal, in the form of particles in an aqueous slurry, is heated under pressure to at least partially release bound water from the coal particles, the bound water being released as liquid water. In one aspect, the coal particles of the slurry are hydraulically milled by means of the slurry water as the slurry pressure is reduced through the milling. In a second aspect, mineral and/or inorganic content is separated from the slurry by a flotation procedure that utilises bubbling of released gases following reduction of the slurry pressure. Also disclosed is corresponding apparatus.
(FR) La présente invention concerne un procédé de traitement de charbon sous forme de particules dans une suspension aqueuse par chauffage sous pression pour libérer au moins partiellement et sous forme liquide l'eau liée aux particules de charbon. Selon un aspect, les particules de charbon dans la suspension sont broyées hydrauliquement au moyen de l'eau de la suspension alors que la pression de cette dernière est réduite par le broyage. Selon un deuxième aspect, les matières minérales et/ou inorganiques sont séparées de la suspension par une procédure de flottation qui utilise le barbotage des gaz libérés après réduction de la pression de la suspension. L'invention concerne également un appareil correspondant.
