Abstract (en)
A nitrogen recovery apparatus (100) for recovering nitrogen from natural gas comprises a separator (110) having a liquid fraction port and a vapour fraction port in fluid communication with a split flow arrangement (112), the split flow arrangement (112) having a sub-cooled fluid path (118) and an expanded fluid path (120). A fractionating column (116) has a reflux inlet port (124) in fluid communication with the subcooled fluid path (118) above a middle feed port (130) thereof, the middle feed port (130) being in fluid communication with the expanded fluid path (120). A bottom feed port (114) of the fractionating column (116) is in fluid communication with the liquid fraction port of the separator (110). A side reboiler circuit (132) and a reboiler circuit (140) are operably coupled to the fractionating column (116) below the bottom feed port (114). A bottom hydrocarbon product stream path (160) is in fluid communication with a bottom hydrocarbon port (162) of the fractionating column (116).
