    Abstract: This method comprises a separation of a feed stream (16) into a first fraction (41A) and a second fraction (41B). It comprises injecting the first cooled feed fraction (42) into a first separating flask (22) to produce a light head stream (44).The method comprises expanding a turbine feed fraction (48) resulting from the light head stream (44) in a first turbine (26) up to a first pressure and injecting the first expanded fraction (54) into a distillation column (30).The method comprises expanding the second fraction of the feed stream (41B) in a second turbine (40) up to a second pressure substantially equal to the first pressure.The second expanded fraction (91A) from the second dynamic expansion turbine (40) is used to form a cooled reflux stream (91B) injected into the column (30).
