Patent number: 8828237Abstract: A filtering device comprises a vessel for containing filtering media such as nutshells. Associated with the filtering device is an eductor for scrubbing and cleaning the media and removing contaminants such as oil from the media. The eductor includes an inlet port for receiving a motive liquid. Further, the eductor includes an inlet port for receiving media held in the vessel. In operation, a motive liquid is directed into the eductor and this induces media in the vessel into the eductor. By continuously directing motive liquid from an external source into the eductor, this results in the media being fluidized and circulated and recirculated through the eductor, giving rise to a slurry that contains liquid, the media and removed contaminants. A portion of the slurry is discharged from the filtering device while the media is retained in the filtering device.Type: GrantFiled: July 25, 2012Date of Patent: September 9, 2014Assignee: Veolia Water Solutions and Technologies SupportInventor: Neville Ernest Lange

Publication number: 20140110358Abstract: 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.Type: ApplicationFiled: February 17, 2012Publication date: April 24, 2014Applicant: VWS WESTGARTH LIMITEDInventor: Neville Ernest Lange

Patent number: 7179386Abstract: Sand is discharged from a vessel at an elevated pressure and is delivered at a lower pressure. The sand is subjected to the following steps before delivery: I) dilution with a dilution fluid, ii) passage through at least one pressure reducing cyclone, the dilution being such that flashing is reduced, and iii) delivery as a slurry at the delivery pressure. This results in less wear of the components.Type: GrantFiled: May 27, 2002Date of Patent: February 20, 2007Assignee: Axsia Serck Baker LimitedInventor: Neville Ernest Lange
