Title (EN) PROCESS FOR SEPARATING SOLIDS FROM COAL LIQUIDS
(FR) PROCEDE DE SEPARATION DES SOLIDES DE LIQUIDES CARBONIFERES
Abstract:
(EN) The rate of separation of suspended mineral particles from a coal liquid is increased by adding a calcium salt, such as calcium carbonate, to the coal liquid. The increase in the separation rate is achieved even though the suspended coal mineral particles naturally contain a calcium salt.
(FR) Le taux de separation de particules minerales en suspension d"un liquide carbonifere est augmente en ajoutant un sel de calcium, tel que du carbonate de calcium au liquide carbonifere. L"augmentation du taux de separation est obtenue meme si les particules minerales carboniferes en suspension contiennent deja naturellement un sel de calcium.
