Abstract

Les cuves de décantation d'écume (FSU) ci-décrites utilisent le puits d'alimentation d'un classificateur pour pré-classer un flux dilué par solvant en trop-plein de bitume et solvant moins dense et en sousverse d'eau, agglomérats de solides et d'asphaltène plus dense. Le trop-plein et la sousverse sont déchargés dans l'unité FSU à des emplacements distants axialement, pour former une interface sensiblement non turbulente entre les deux. La majeure partie du bitume et du solvant dans le trop-plein s'élève jusqu'à la partie supérieure, après déchargement au-dessus de l'interface, et la majorité des composants dense tombe au fond, après déchargement au-dessous de l'interface. Des quantités mineures de composants moins denses dans la sousverse et de composants plus denses dans le trop-plein s'élèvent et tombent sensiblement librement à travers l'interface. L'unité FSU selon l'invention peut être utilisée à des débits excédant ceux d'une FSU classique dans la mesure où le risque de rupture est réduit au minimum suite à la pré-classification et à un déchargement à des emplacements distincts au sein de l'unité FSU.
