Abstract
A method for cooling a natural gas stream (CH) and separating the cooled gas stream into various fractions having different boiling points, such as methane, ethane, propane, butane and condensates, comprises: cooling the gas stream (); and separating the cooled gas stream in an inlet separation tank (); a fractionating column () in which a methane lean rich fluid fraction (CH) is separated from a methane lean fluid fraction (C+H); feeding at least part of the methane enriched fluid fraction from the inlet separation tank () into a cyclonic expansion and separation device (), which preferably has an isentropic efficiency of expansion of at least 80%, such as a supersonic or transonic cyclone; and feeding the methane depleted fluid fraction from the cyclonic expansion and separation device () into the fractionating column () for further separation.
