Publication number: 20110265511Abstract: The liquefaction method provides fractionation of the natural gas with ethane recycle in order to enhance propane recovery and to increase the critical pressure of the gas to be liquefied. The natural gas is partly liquefied by cooling in E1, then separated in fractionating column 2 into a methane-rich stream and a stream rich in hydrocarbons heavier than methane. The methane-rich stream is partly liquefied in 3, then the condensates separated in drum 4 are recycled to the top of column 2 through line 7. The gas fraction from drum 4 is liquefied in exchanger E2 to produce the liquefied natural gas. The stream rich in hydrocarbons heavier than methane is separated in the deethanizer into an ethane-enriched fraction and heavier hydrocarbons. According to the invention, the ethane-enriched fraction is at least partly liquefied, then part of the liquefied ethane is recycled to separating drum 4 or reflux line 7.Type: ApplicationFiled: October 17, 2008Publication date: November 3, 2011Applicant: IFPInventors: Beatrice Fischer, Anne Lucquin, Gilles Ferschneider, Pierre-Yves Martin, Jerome Pigourier

Patent number: 6763680Abstract: Natural gas liquefaction method wherein the natural gas is cooled, condensed and subcooled by indirect heat exchange with two cooling mixtures to a temperature such that the natural gas does not remain entirely liquid under pressure after expansion to the atmospheric pressure. The liquid natural gas under pressure is expanded to form a gas phase and a liquid phase. The gas phase can be either compressed and recycled to the process inlet, or used as a fuel. The liquid phase is expanded to form a gas phase and a liquid phase. The gas phase is compressed and recycled to the process inlet. The liquid phase constitutes the liquefied natural gas produced.Type: GrantFiled: June 20, 2003Date of Patent: July 20, 2004Assignee: Institut Francais du PetroleInventors: Béatrice Fischer, Pierre-Yves Martin, Alexandre Rojey
