Title (EN) ENHANCED SYSTEM FOR SAND CLEANING IN A HYDROCYCLONE
(FR) SYSTÈME DE NETTOYAGE
Abstract: front page image
(EN)Enhanced system for sand cleaning in a hydrocyclone The invention relates to a system (100) for the cleaning of sand, originating from subterranean oil production and comprises separation of sand from adhering oil out of a sand/oil/water slurry. The sand is cleaned through treatment in a hydrocyclone (13) through rubbing against themselves and the walls of the hydrocyclone. The hydrocyclone discharges the larger/heavier particles into a vessel (1), wherein the vessel has a discharge port (3) for the sand. A fluid extractor (34) is provided between the hydrocyclone (13) and the discharge port of the vessel (1), for extracting fluid from the vessel (1) to permit an increased flow rate of sand into the vessel. The invention also relates to a method of cleaning sand and a method of increasing the flow rate of sand through a hydrocyclone cleaning system as described above.
(FR)L'invention porte sur un système de nettoyage pour le nettoyage de sable à hydrocyclone, lequel système de nettoyage comprend un hydrocyclone destiné à recevoir une boue contenant du sable à nettoyer et une cuve destinée à recevoir du sable sortant de l'hydrocyclone, la cuve ayant un orifice d'évacuation pour le sable. Un extracteur de fluide est disposé entre l'hydrocyclone et l'orifice d'évacuation pour extraire le fluide de la cuve, afin de permettre un débit accru de sable dans la cuve. L'invention porte également sur un procédé de nettoyage de sable et sur un procédé d'augmentation du débit de sable à travers un système de nettoyage à hydrocyclone, tel que celui décrit ci-dessus.
