Patent number: 9222724Abstract: The method provides liquefaction of a natural gas by carrying out the following stages: cooling the natural gas; feeding the cooled natural gas into a fractionating column so as to separate a methane-rich gas phase and a liquid phase rich in compounds heavier than ethane; and liquefying the methane-rich stream so as to obtain the liquid natural gas. According to the invention, the operating conditions in the fractionating column are so selected that said liquid phase comprises a molar proportion of methane ranging between 10% and 150% of the molar proportion of ethane.Type: GrantFiled: October 17, 2008Date of Patent: December 29, 2015Assignee: IFP Energies NouvellesInventors: Béatrice Fischer, Gilles Ferschneider, Anne Claire Lucquin

Patent number: 8313092Abstract: A gas-liquid contact column tray has a section including a gas pathway (SAA) and a liquid pathway section (SD) delimited by at least one downspout, wherein a deflecting system including a roof is included, located above the liquid gas interface at the level of the liquid pathway section (SD), in order to apportion the gas phase over a surface section greater than the section including the means of gas pathway (SAA). In a method for gas-liquid contact in such a column, most of the gas phase part is redirected and apportioned over the whole pathway section available for gas, corresponding to the tray section provided with the gas pathway (SAA), increased by the liquid pathway section (SD), using a deflecting system consisting of the roof located higher than the gas-liquid interface level of the liquid pathway section (SD), and the liquid collected is evacuated toward the lower tray.Type: GrantFiled: December 5, 2011Date of Patent: November 20, 2012Assignee: IFPInventors: Ludovic Raynal, Anne-Claire Lucquin

Patent number: 7803271Abstract: The invention provides a method of extracting the hydrogen sulfide contained in a gas comprising aromatic hydrocarbons, wherein the following stages are carried out: a) contacting said gas with an absorbent solution so as to obtain a gas depleted in hydrogen sulfide and an absorbent solution laden with hydrogen sulfide, b) heating and expanding the hydrogen sulfide-laden absorbent solution to a predetermined temperature and pressure so as to release a gaseous fraction comprising aromatic hydrocarbons and to obtain an absorbent solution depleted in aromatic hydrocarbons, said temperature and pressure being so selected that said gaseous fraction comprises at least 50% of the aromatic hydrocarbons and at most 35% hydrogen sulfide contained in said hydrogen sulfide-laden absorbent solution, c) thermally regenerating the absorbent solution depleted in aromatic hydrocarbon compounds so as to release a hydrogen sulfide-rich gaseous effluent and to obtain a regenerated absorbent solution.Type: GrantFiled: February 6, 2007Date of Patent: September 28, 2010Assignees: Institut Francais du Petrole, Total SAInventors: Julia Magne-Drisch, Anne-Claire Lucquin, Christina Streicher, Jean Elgue, Jean-Paul Cousin, Gauthier Perdu, Damien Roquet, Viep Hoang Dinh
