Abstract (en)
[origin: WO2012052681A2] The invention relates to a method which includes cooling the feed natural gas (15) in a first heat exchanger (16), and feeding the cooled feed natural gas (40) into a disengager (18). The method includes dynamically expanding a turbine input flow (46) in a first expansion turbine (22), and feeding the expanded flow (102) into a splitter (26). Said method comprises sampling, at the head of the splitter (26), a methane-rich head stream (82) and sampling, from the compressed methane-rich head stream (86), a first recirculation stream (88). The method includes forming at least one second recirculation stream (96) obtained from the methane-rich head stream (82) downstream from the splitter (26), and forming a dynamic expansion stream (100) from the second recirculation stream (96).
