  • the invention relates to a process for obtaining a helium-rich product fraction from a feed fraction comprising essentially carbon dioxide, helium, methane and higher hydrocarbons.
  • the outflowing gas mixture consists to a large extent of carbon dioxide.
  • the carbon dioxide content is usually between 70 and 98% by volume.
  • the gas mixture low proportions of methane - usually between 0.1 and 20% by volume - and heavier hydrocarbons and helium shares up to 1% by volume.

  • a fuel gas fraction can additionally be obtained.
  • the helium-enriched fraction in the heat exchanger X 1 is only condensed and then fed to a separator, not shown in the figure 2. From the bottom of this separator, a methane-rich liquid fraction is separated, expanded to the desired fuel gas pressure, warmed in the heat exchanger X 'and discharged as a fuel gas fraction. The withdrawn at the top of the separator, depleted of methane gas fraction is further cooled in the heat exchanger X 'and driven via line 5' in the separation column B '.
  • all the compressor units are designed as cost-effective screw compressor, but this only applies if the pressure conditions are favorable for the screw compressor.
  • the helium-rich product fraction 7 withdrawn from the adsorption process F can be fed directly to a helium liquefaction process without further processing. It is a helium recovery rate of up to 100% feasible, provided that the carbon dioxide separation takes place by means of a separation column B; In this case, the integration of the Aufkochers 10 in the heat exchanger X allows a particularly energy-saving process.

Abstract

L'invention concerne un procédé pour extraire une fraction riche en hélium d'une fraction de départ contenant essentiellement du dioxyde de carbone, de l'hélium, du méthane et des hydrocarbures supérieurs. Le procédé comprend les étapes suivantes: a) séparation du dioxyde de carbone (B) de la fraction de départ (1, 2), b) séparation par adsorption (C) de la fraction (3) appauvrie en dioxyde de carbone résultant de la séparation du dioxyde de carbone (B) en une fraction résiduelle riche en dioxyde de carbone (11) et en une fraction enrichie en hélium (4, 5), c) séparation cryogénique de l'azote, du méthane et des hydrocarbures supérieurs (E) de la fraction enrichie en hélium (4, 5) et d) séparation par adsorption (F) de la fraction appauvrie en azote (6) résultant de la séparation cryogénique de l'azote (E) en une fraction résiduelle riche en azote (13) et en la fraction riche en hélium (7).
