Abstract

L'invention concerne un procédé/dispositif permettant la séparation continue d'un milieu liquide comprenant un diluant et des monomères non polymérisés, d'un effluent de polymérisation. Dans ce procédé et ce dispositif, l'effluent de polymérisation d'un réacteur de polymérisation en suspension est déchargé en continu à travers une vanne de décharge, et un conduit de transfert, dans un premier séparateur à pression intermédiaire. Ce premier séparateur présente un fond conique défini par des parois latérales sensiblement droites, inclinées de manière à former avec l'horizontale un angle égal ou supérieur à l'angle de déversement de l'ensemble suspension/polymères solides, et une chambre de sortie étanche présentant un diamètre (d) et une longueur (l) définies de manière à retenir un volume donné de polymères solides/suspension dans la chambre de sortie étanche, ce qui assure une fermeture étanche, un flux périodique de polymères solides/suspension résiduels concentrés provenant du premier séparateur étant simultanément déchargé en continu hors de la chambre de sortie étanche dans un second séparateur présentant une pression plus basse, à travers un réducteur de sortie associé la chambre étanche, ce réducteur présentant des parois latérales inclinées de manière à former avec l'horizontale un angle égal ou supérieur à l'angle de déversement des polymères solides qui restent après l'élimination de 50 à 100 % environ du diluant inerte de ce dernier.
