(EN) SYSTEM FOR ENHANCED FUEL GAS COMPOSITION CONTROL IN AN LNG FACILITY
(FR) SYSTÈME POUR UNE RÉGULATION ACCRUE DE COMPOSITION DE GAZ COMBUSTIBLE DANS UN ÉQUIPEMENT GNL
Abrégé
(EN)
An LNG facility employing an enhanced fuel gas control system. The enhanced fuel gas control system is operable to produce fuel gas having a substantially constant Modified Wobbe Index (MWI) during start-up and steady-state operation of the LNG facility by processing one or more intermediate process streams in a fuel gas separator. In one embodiment, the fuel gas separator employs a hydrocarbon-separating membrane, which can remove heavy hydrocarbons and/or concentrate nitrogen from the incoming process streams.
(FR)
L'invention concerne un équipement GNL (gaz naturel liquéfié) employant un système de régulation accrue de gaz combustible. Le système de régulation accrue de gaz combustible est opérationnel pour produire du gaz combustible ayant un indice de Wobbe modifiable (MWI) sensiblement constant pendant le démarrage et un fonctionnement en régime permanent de l'équipement GNL par traitement d'un ou plusieurs courants de traitement intermédiaires dans un séparateur de gaz combustible. Dans un mode de réalisation, le séparateur de gaz combustible emploie une membrane de séparation d'hydrocarbure, qui peut éliminer les hydrocarbures lourds et/ou concentrés d'azote provenant du traitement de courants entrants.
