Title (EN) IMPROVED METHOD FOR SEPARATING SOLIDS FROM COAL LIQUIDS
(FR) METHODE AMELIOREE DE SEPARATION DE SOLIDES DE LIQUIDES CARBONIFERES
Abstract: front page image
(EN)The rate of separation of suspended mineral particles from a coal liquid is increased by adding a mixture of a hydrocarbonaceous oil and a calcium salt, such as calcium carbonate, to the coal liquid. The increase in the separation rate is achieved even though the coal mineral particles naturally contain a calcium salt. The premixing of the calcium salt with hydrocarbonaceous oil considerably enhances the separation rate as compared to the addition of the calcium salt alone even when the hydrocarbonaceous oil is a distillate fraction which is derived from the coal liquid itself.
(FR)Le taux de separation de particules minerales en suspension dans un liquide carbonifere est ameliore en ajoutant un melange d"hydrocarbure et d"un sel de calcium, tel que du carbonate de calcium, au liquide carbonifere. On obtient une telle amelioration meme si les particules minerales carboniferes contiennent deja, naturellement, un sel de calcium. Le premelange du sel de calcium avec l"hydrocarbure ameliore considerablement le taux de separation par comparaison avec l"addition du sel de calcium seul meme lorsque l"hydrocarbure est un produit de distillation fractionnee qui est derive du liquide carbonifere lui-meme.
