Abstract[English]
Systems and methods for producing light olefins from a natural gas liquid (NGL) or other C5 stream are provided. The method may include supplying a NGL or other C5 stream to a reverse isomerization unit to produce a n-pentane enriched NGL stream and supplying the n- pentane enriched NGL stream to a liquid furnace to produce a pyrolyzed product stream. The method may also include separating the C2 hydrocarbons, the C3 hydrocarbons, the C4 hydrocarbons, the C5 hydrocarbons, and the C6+ hydrocarbons in the pyrolyzed product stream in a separation train and supplying the separated C5 hydrocarbons, or a portion thereof, to a hydrogenation reactor to produce a saturated C5 hydrocarbon stream, followed by recycling the saturated C5 hydrocarbon stream to the reverse isomerization unit.[French]
L'invention concerne également des systèmes et des procédés de production d'oléfines légères à partir d'un liquide de gaz naturel (LGN) ou d'un autre flux en C5. Le procédé peut consister à fournir un LGN ou un autre flux en C5 à une unité d'isomérisation inverse pour produire un flux de LGN enrichi en n-pentane et à fournir le flux de LGN enrichi en n-pentane à un four à liquide pour produire un flux de produit pyrolysé. Le procédé peut également consister à séparer les hydrocarbures en C2, les hydrocarbures en C3, les hydrocarbures en C4, les hydrocarbures en C5 et les hydrocarbures en C6+ dans le flux de produit pyrolysé dans un train de séparation et à fournir les hydrocarbures en C5 séparés, ou une partie de ceux-ci, à un réacteur d'hydrogénation pour produire un flux d'hydrocarbures en C5 saturé, suivi par le recyclage du flux d'hydrocarbures en C5 saturé vers l'unité d'isomérisation inverse.
