Title (EN) TREATMENT OF EMULSIONS
(FR) TRAITEMENT D'EMULSIONS
Abstract:
(EN) A filtration system for treating an emulsion containing water, an oil or a fat, an emulsifying agent and insoluble solid material (such as a maritime oil emulsion containing an anionic detergent and the solid, greasy calcium salt of the detergent) has a first hydrophobic microfilter (126) and a second hydrophobic microfilter (147). Both microfilters (126, 147) have a plurality of hollow porous fibres as the separating medium with the feed to the first filter (126) being applied to the outside of the fibres and the feed to the second filter (which is the permeate from the first filter) being applied down the lumens of the fibres. The first filter (126) removes the solid material and the second filter separates the oil or fat from the solid-free emulsion.
(FR) Un système de filtrage pour le traitement d'une émulsion contenant de l'eau, une huile ou une graisse, un agent émulsifiant et un matériau solide insoluble (tel qu'une émulsion d'huile maritime contenant un détergent anionique et son sel de calcium graisseux solide) comprend un premier microfiltre hydrophobe (126) et un second microfiltre hydrophobe (147). Les deux microfiltres (126, 147) comprennent plusieurs filtres poreux creux comme agent de séparation, la substance d'alimentation du premier filtre (126) étant appliquée à l'extérieur des fibres et la substance d'alimentation du second filtre (substance qui est constituée du perméat provenant du premier filtre) étant appliquée vers le bas des orifices des fibres. Le premier filtre (126) retire le matériau solide et le second filtre sépare l'huile ou la graisse de l'émulsion exempte du substance solide.
