Patent number: 11298661Abstract: The present invention is a filtration system and a method for cleaning a filtration system. The filtration system comprising a hydraulic circuit Cp recycling the permeate stream to the feed side of the membrane and/or a hydraulic circuit Cr recycling the retentate stream to the feed side of said membrane. The method injects an amount of a chemical product into the filtration system in the hydraulic circuit Cp or in the hydraulic circuit Cr or upstream of the cross-flow filtration membrane, setting the proportion of recycled permeate stream or recycled retentate stream collected in the hydraulic circuit Cp and/or Cr to enable the recycling of a significant amount of unreacted chemical product having passed through the cross-flow filtration membrane to the feed side of said cross-flow filtration membrane.Type: GrantFiled: July 1, 2016Date of Patent: April 12, 2022Assignees: TOTAL SA, VEOLIA WATER SOLUTIONS TECHNOLOGIES SUPPORT, SAIPEM S.A.Inventors: Jérôme Anfray, Pierre Pedenaud, Graeme Skivington, Thomas Delaplace

Patent number: 10414673Abstract: A method for testing an underwater filtration system as well as the underwater testing device which enables the operation of filtration systems in aquatic conditions. The testing method includes introducing a flow of water into the underwater testing device via a water inlet, said underwater testing device including at least one filter, bringing said flow in the underwater testing device up to said filter, obtaining a filtrate downstream of said filter and discharging said filtrate into the environment via a discharge pipe. The underwater testing device is placed underwater at a depth of at least 500 meters.Type: GrantFiled: September 19, 2013Date of Patent: September 17, 2019Assignees: TOTAL SA, SAIPEM S.A., VEOLIA EAU—COMPAGNIE GENERALE DES EAUX, VWS WESTGARTH LTD.Inventors: Pierre Pedenaud, Samuel Heng, Didier Bigeonneau, Stéphane Anres, Raymond Hallot, Michel Baylot, Mourad Ben Boudinar, Graeme Skivington

Publication number: 20190168166Abstract: The present invention concerns a method for cleaning a filtration system under operation. The filtration system comprising a hydraulic circuit Cp recycling the permeate stream to the feed side of the membrane and/or a hydraulic circuit Cr recycling the retentate stream to the feed side of said membrane. The method comprises injecting an amount of a chemical product into the filtration system in the hydraulic circuit Cp or in the hydraulic circuit Cr or upstream of the cross-flow filtration membrane, setting the proportion of recycled permeate stream or recycled retentate stream collected in the hydraulic circuit Cp and/or Cr to enable the recycling of a significant amount of unreacted chemical product having passed through said cross-flow filtration membrane to the feed side of said cross-flow filtration membrane, as well as a filtration system for carrying out said method.Type: ApplicationFiled: July 1, 2016Publication date: June 6, 2019Applicants: T0TAL SA, VEOLIA WATER SOLUTIONS & TECHNOLOGIES SUPPORT, SAIPEM S.A.Inventors: Jérôme ANFRAY, Pierre PEDENAUD, Graeme SKIVINGTON, Thomas DELAPLACE

Publication number: 20160040522Abstract: The invention relates to a method for extracting hydrocarbons. The steps involve extracting a process flow from an underground formation, separating this flow into at least one hydrocarbon-containing fraction and one aqueous fraction referred to as the produced water, and reinjcting an injection water into the underground formation. The injection water intended to be introduced into the underground formation is produced partly in a direct-osmosis unit from produced water and partly in a nanofiltration and/or reverse-osmosis unit. The invention also relates to a process for extracting hydrocarbons throughout the exploitation life of the underground hydrocarbon reservoir, and to an injection-water production device especially designed for implementing this process.Type: ApplicationFiled: April 1, 2014Publication date: February 11, 2016Inventors: Matthieu Jacob, Nicolas Lesage, Pierre Pedenaud, Philippe Coffin
