Title (EN) INTEGRATED NGL RECOVERY AND LNG LIQUEFACTION
(FR) RECUPERATION DE GAZ NATUREL LIQUEFIE ET LIQUEFACTION DES LIQUIDES DU GAZ NATUREL INTEGRES
Abstract: front page image
(EN)Contemplated plants include a refluxed absorber and a distillation column, wherein the absorber is operated at a higher pressure than the distillation column to thereby produce a cryogenic pressurized lean gas. The lean gas is further compressed to a pressure suitable for liquefaction using energy from feed gas vapor expansion. Desired separation of C2 products is ensured by temperature control of the absorber and distillation column using flow ratios of various streams within the plant, and by dividing the separation process into two portions at different pressures.
(FR)L'invention concerne des installations comportant un absorbeur à reflux et une colonne de distillation, l'absorbeur fonctionne à une pression plus élevée que la colonne de distillation pour ainsi produire un gaz pauvre pressurisé cryogénique. Le gaz pauvre pressurisé est davantage comprimé à une pression convenant à la liquéfaction à l'aide de l'énergie issue de l'expansion des vapeurs de gaz d'alimentation. La séparation souhaitée des produits C2 est garantie par la commande de température de l'absorbeur et de la colonne de distillation à l'aide de débits de divers courants dans l'installation, et par division du processus de séparation en deux parties à des pressions différentes.
