Title (EN) PURIFICATION OF OIL
(FR) PURIFICATION D'HUILE
Abstract:
(EN) A method and a system for purification of contaminated oil. Said method comprises the steps of: -providing contaminated oil and a separation aid in a tank(3); -waiting for allowing a sludge phase comprising the separation aid together with impurities from the oil to settle in a bottom part (4) of the tank(3); -reusing the sludge phase for purification of new contaminated oil.
(FR) L'invention concerne un procédé et un système de purification d'huile contaminée. Ledit procédé comprend les étapes consistant à :-fournir de l'huile contaminée et une aide de séparation dans un réservoir (3);-attendre pour permettre à une phase de boue comprenant l'aide de séparation conjointement avec des impuretés de l'huile de se déposer dans une partie inférieure (4) du réservoir (3);-réutiliser la phase de boue pour la purification de nouvelle huile contaminée.
