Title
(EN) A METHOD OF SEPARATING, FROM A MIXTURE OF BLACK LIQUOR AND TALL OIL SOAP PRODUCT, CONCENTRATED PORTIONS OF TALL OIL SOAP PRODUCT AND ARRANGEMENTS FOR SAID CONCENTRATED TALL OIL SOAP PRODUCT AND/OR SEPARATED BLACK LIQUOR
(FR) PROCÉDÉ DE SÉPARATION DE FRACTIONS CONCENTRÉES DE SAVON À L'HUILE DE PIN À PARTIR D'UN MÉLANGE DE LIQUEUR NOIRE ET DE SAVON À L'HUILE DE PIN, ET DISPOSITIFS CONVENANT POUR LE SAVON À L'HUILE DE PIN CONCENTRÉ ET/OU LA LIQUEUR NOIRE SÉPARÉE
Abstract
(EN) This invention concerns a continuous method and an arrangement for separation of crude tall oil (CTO) from black liquor. The method involves an initial separation within a tank and/or within a centrifugal separator, and processing of the thus separated tall oil soap product by acidulation and/or splitting, followed by further separation, e.g. by centrifugation. The black liquor fraction may be processed for further CTO retrieval, before evaporation and feeding to a recovery boiler.
(FR) La présente invention concerne un procédé continu et un dispositif permettant de séparer, de la liqueur noire, le tallöl brut ou "CTO" (Crude Tall Oil). Ce procédé consiste à effectuer une première séparation à l'intérieur d'une cuve et/ou à l'intérieur d'un séparateur centrifuge, puis à traiter le savon à l'huile de pin obtenu par acidulation et/ou fractionnement, et ensuite à effectuer une séparation supplémentaire, par exemple par centrifugation. La fraction de liqueur noire peut être traitée en vue d'un supplément de récupération de CTO, avant d'être évaporée et de venir alimenter une chaudière à liqueur noire.
