Title (EN) CONFIGURATIONS AND METHODS FOR RETROFITTING AN NGL RECOVERY PLANT
(FR) CONFIGURATIONS ET PROCÉDÉS DE RÉHABILITATION THERMIQUE D'INSTALLATION DE RÉCUPÉRATION DE LGN
Abstract:
(EN) Devices and methods for retrofitting a natural gas liquids plant are contemplated to extend recovery of C3+ hydrocarbons from various feed gases to recovery of C2+ and C3+ hydrocarbons. In especially preferred aspects, dedicated C2+ exchangers are integrated to exclusively cool the feed gas to produce a cooled absorber feed and to produce two separate absorber reflux streams. During C2+ recovery, absorber reflux is provided by a portion of the residue gas and a portion of the feed gas, while during C3+ recovery absorber and distillation column reflux are provided by the distillation column overhead product.
(FR) L'invention concerne des dispositifs et des procédés de réhabilitation thermique d'une installation de production de liquides du gaz naturel, lesdits dispositifs et procédés permettant d'étendre la récupération d'hydrocarbures en C3+ provenant de divers gaz d'alimentation à la récupération d'hydrocarbures en C2+ et C3+. Selon des aspects particulièrement préférés, des échangeurs de chaleur avec les C2+ dédiés sont intégrés pour refroidir exclusivement le gaz d'alimentation afin de produire une charge d'absorbeur refroidie et deux courants de reflux d'absorbeur séparés. Pendant la récupération des C2+, le reflux de l'absorbeur est fourni par une partie du gaz résiduaire et une partie du gaz d'alimentation, alors que pendant la récupération des C3+ les reflux de l'absorbeur et de la colonne de distillation sont fournis par le produit de tête de la colonne de distillation.
