Title
(EN) COAL PREPARATION
(FR) PREPARATION DE CHARBON
Abstract
(EN)
Deashing of coal is achieved by oil agglomeration and subsequent separation of a carbon oil phase. The oil is removed by steam stripping either simultaneously and/or after the coal oil agglomerates have been disintegrated. The fine coal product can be used in steam generating plants such as power stations.
(FR)
L"elimination des cendres de charbon s"effectue par agglomeration d"huile puis separation d"une phase huileuse. L"huile est enlevee par extraction a la vapeur soit simultanement et/ou apres que les agglomerats d"huile se soient desintegres. Le produit de charbon fin peut etre utilise dans des usines de production de vapeur telle que des centrales electriques.
