Title (EN) DEWATERING FINE COAL SLURRIES USING TWO TYPES OF ORGANOPOLYSILOXANES
(FR) ASSECHAGE DE BOUES DE CHARBON FIN PAR L'UTILISATION DE DEUX TYPES D'ORGANOPOLYSILOXANES
Abstract: front page image
(EN)Aqueous slurries of fine coal are dewatered by a process which comprises mixing a mixture of a water-soluble organopolysiloxane and a water-emulsifiable organopolysiloxane with the slurry, separating the slurry to recover the fine coal and further drying the fine coal, if desired. The use of a mixture of a water-soluble organopolysiloxane and a water-emulsifiable organopolysiloxane unexpectedly provides improved separating and/or improved drying of fine coal compared to a dewatering process that uses only one of the organopolysiloxanes.
(FR)Les boues aqueuses de charbon fin sont assechees par un procede consistant a melanger avec la boue un melange d'un organopolysiloxane soluble a l'eau et d'un organopolysiloxane emulsifiable dans l'eau, separer la boue pour recuperer le charbon fin et secher facultativement le charbon fin. L'utilisation d'un melange d'un organopolysiloxane soluble a l'eau et d'un organopolysiloxane emulsifiable dans l'eau permet une separation et/ou un sechage ameliores du charbon fin par rapport a un procede d'assechage utilisant un seul des organopolysiloxanes.
