摘要: Method of, and apparatus for, rejecting nitrogen from a hydrocarbon stream to provide fuel gas stream. A is at least partially liquefied subsequently expanded. The expanded fractionated in fractionation column an nitrogen-rich nitrogen-lean condensed condenser by cooling against refrigerant circulated dedicated first circuit, phase-separated nitrogen-rejection reflux which returned the column. vaporized vapour that subjected sub-cooling. generated sub-cooled
