Title (EN) HYDROCYCLONE FOR SEPARATING IMMISCIBLE FLUIDS AND REMOVING SUSPENDED SOLIDS
(FR) HYDROCYCLONE PERMETTANT DE SEPARER DES FLUIDES NON MISCIBLES ET DE RETIRER DES SOLIDES EN SUSPENSION
Abstract:
(EN) The invention relates to a cyclone separator for separating oil and water and removing suspended solids. It comprises a generally cylindrical first portion with an open end and a closed end. A generally axial overflow outlet is provided in the closed end and preferably a moveable member is associated with this closed end having a plurality of orifices of progressively smaller diameter than the overflow outlet. This moveable member may be moved such that any selected one of the plurality of orifices may be axially aligned with the overflow outlet. The separator includes at least two radially balanced feed injection ports in the cylindrical first portion adjacent to the closed end thereof. A converging tapered second section with open ends is axially flow connected to the open end of the cylindrical first portion and a converging tapered third portion with open ends is axially flow connected to the tapered second portion. A fourth generally cylindrical portion is axially flow connected to the third tapered portion. This separation is of particular value in heavy oil production.
(FR) Cette invention concerne un séparateur de type cyclone qui permet de séparer l'huile et l'eau et de retirer les solides en suspension. Ce séparateur comprend une première partie globalement cylindrique qui possède une extrémité ouverte et une extrémité fermée. Une ouverture de trop-plein globalement axiale est pratiquée dans l'extrémité fermée, tandis qu'un élément mobile est de préférence associé à cette extrémité fermée, et possède plusieurs orifices dont le diamètre se réduit progressivement par rapport à celui de l'ouverture de trop-plein. Cet élément mobile peut se déplacer de manière à ce que n'importe lequel des orifices puisse être aligné axialement à l'ouverture de trop-plein. Le séparateur comprend au moins deux orifices d'alimentation par injection qui sont équilibrés radialement et qui sont situés dans la première partie cylindrique à proximité de l'extrémité fermée de celle-ci. Une deuxième partie convergente et conique possédant des extrémités ouvertes est connectée axialement à l'extrémité ouverte de la première partie cylindrique de manière à assurer l'écoulement. Une troisième partie convergente et conique possédant des extrémités ouvertes est connectée axialement à la deuxième partie conique de manière à assurer l'écoulement. Une quatrième partie globalement cylindrique est enfin connectée axialement à la troisième partie conique de manière à assurer l'écoulement. Cette séparation offre un intérêt tout particulier dans la production d'huile lourde.
