  • LNG liquefied natural gas
  • a common hydrocarbon stream for a fuel gas stream comprises, or essentially consists of, natural gas (NG) .
  • NG natural gas
  • natural gas comprising predominantly methane
  • the purified gas is processed through a plurality of cooling stages using heat exchangers to progressively reduce its temperature until liquefaction is achieved.
  • the liquid natural gas is then further cooled and expanded to final atmospheric pressure suitable for storage and transportation .
  • the cooling duty in the first fractionation is provided by a condensed nitrogen reflux stream.
  • the condensed nitrogen reflux stream is provided by heat exchange against an expanded cold liquefied natural gas stream from the main heat exchanger, providing an undesirable surplus of fuel gas.
  • additional cooling duty for the nitrogen rejection is ultimately provided by the mixed refrigerant circuit used in the main cooling stage. This increases the load placed on the mixed refrigerant main cooling cycle, requiring larger refrigerant compressors of greater power, increased refrigerant cooling etc., resulting in a reduced power capacity limited by available compressor driver size. It is an object of the present invention to address these problems, by providing an improved process for rejecting nitrogen from a hydrocarbon stream.
  • the present invention seeks to provide a process which reduces the load on the main cooling cycle.
  • the present invention provides a method of rejecting nitrogen from a hydrocarbon stream to provide a fuel gas stream, comprising at least the steps of: (a) at least partly liquefying a hydrocarbon stream in a heat exchanger to provide a cooled hydrocarbon stream;

Abstract

L'invention concerne un procédé et un appareil (1) permettant de rejeter l'azote d'un flux d'hydrocarbure (10) pour produire un flux de gaz combustible (510). Un flux d'hydrocarbure (10) est au moins partiellement liquéfié et, par la suite, détendu. Le flux d'hydrocarbure détendu (110) est fractionné dans une colonne de fractionnement (150) pour produire un flux d'hydrocarbure riche en azote (160) et un flux d'hydrocarbure pauvre en azote (170). Le flux d'hydrocarbure riche en azote (160) est partiellement condensé dans un condenseur (200) par refroidissement contre un réfrigérant que l'on fait circuler dans un premier circuit réfrigérant spécialisé (800), et qui est séparé en phase pour produire un flux de rejet d'azote (260) et un flux de reflux pauvre en azote (270) que l'on retourne vers la colonne de fractionnement (150). Le flux d'hydrocarbure pauvre en azote (170) est partiellement vaporisé et séparé en phase pour produire un flux de vapeur que l'on retourne à la colonne de fractionnement (150) et un flux d'hydrocarbure pauvre en azote (370) que l'on soumet à un sous-refroidissement. Le flux de gaz combustible (510) est généré à partir du flux d'hydrocarbure pauvre en azote (410).
