Abstract
A method comprising the cooling of the feed natural-gas () in a first heat exchanger () and the introduction of the cooled feed natural-gas () in separator flask (). The method further comprising dynamic expansion of a turbine input flow () in a first expansion turbine () and the introduction of the expanded flow () into a splitter column (). This method includes sampling at the head of the splitter column () a methane-rich head stream () and sampling in the compressed methane-rich head stream () a first recirculation stream (). The method comprises the formation of at least one second recirculation stream () obtained from the methane-rich head stream () downstream from the splitter column () and the formation of a dynamic expansion stream () from the second recirculation stream ().
