Patent number: 11959593Abstract: The invention relates to a method for detection of a leak from a tank for liquid gas, said tank comprising a membrane surrounding the liquid gas, the membrane being surrounded by an insulation space which separates the membrane from a wall, the insulation space being filled an inert gas which is injected and extracted by at least one duct. The detection method comprises the following steps: determining 921 a first variation of mass of inert gas ?M1 between two moments by measuring the gas added and removed by the duct; calculating 922 a second variation of mass of inert gas ?M2 corresponding to a difference between two masses of inert gas measured in the insulation space; and comparing 931 the first variation with the second variation, and triggering an alarm if a difference E1 between the first variation and the second variation of mass of inert gas is greater than a first threshold S1.Type: GrantFiled: December 16, 2019Date of Patent: April 16, 2024Assignee: Gaztransport Et TechnigazInventors: Bertrand Bugnicourt, Laurent Spittael, Nicolas Dupont, Jean-Yves Le Stang

Publication number: 20220033040Abstract: The invention relates to a method for managing maintenance for a ship comprising a sealed and thermally insulating tank for transporting liquefied gas. The method comprises the steps consisting in determining 310 a current filling level of the tank, determining 320 a current state of movement of the ship, determining 330 a current sloshing index IBi from the current filling level of the tank and the current state of movement of the ship, taking into account the position and the geometry of the tank, integrating 340 the determined current sloshing index IBi into a wear index IUi that takes into account a history of the sloshing indices. The wear index is then compared to a threshold in order to indicate if the tank needs to be inspected, depending on the result of the comparison.Type: ApplicationFiled: November 12, 2019Publication date: February 3, 2022Inventors: Nicolas Dupont, Florent Ouvrard

Patent number: 9126166Abstract: The present invention relates to a method for filling a multitube catalytic reactor and to a set of inserts suited to implementing this method. The method of the invention is based on the use of inserts of different types allowing superposed layers of catalysts to be placed in the reaction compartments. The heads of the inserts are visually distinct according to the type of insert, making it possible to avoid filling errors and thus allowing the various layers of catalyst to be filled reliably and simultaneously on a reactor scale.Type: GrantFiled: April 1, 2014Date of Patent: September 8, 2015Assignee: Arkema FranceInventors: Nicolas Dupont, Emmanuel Lambert, Arnaud Souet, David Urbaniak
