Abstract

Procédé et dispositif pour l'élimination de boues. On élimine des boues huileuses du fond d'une installation 4 en amenant un gaz, sous la forme de petites bulles, à traverser lesdites boues de sorte qu'un mélange de boues et de gaz s'élève dans un collecteur 9 et passe dans une colonne montante 10 débouchant hors de l'installation 4. Ce procédé et ce dispositif permettent d'éliminer du fond de réservoirs, de séparateurs ou de mares, des boues notamment de raffineries, de façon continue et mécanique, et ils permettent également de réaliser une première séparation des huiles ou du petrole qui sont associés auxdites boues.
