Abstract
Det beskrives en fremgangsmåte for flytendegjøring av naturgass og gjenvinning av komponenter tyngre enn metan, der naturgass avkjøles og separeres i en første destillasjonskolonne til en toppdamp anriket på metan og en bunnstrøm anriket på komponenter tyngre enn metan, der den første destillasjonskolonne benytter en flytendegjort, metanholdig refluksstrøm. Denne refluksstrøm kan tilveiebringes ved hjelp av en kondensert del av toppdampen eller en del av totalt kondensert toppdamp som deretter oppvarmes. Bunnstrømmen kan separeres i en eller flere ytterligere destillasjonskolonner for å gi en eller flere ytterligere produktstrømmer, hver av hvilke helt eller delvis trekkes av som gjenvundne hydrokarboner. En strøm av ikkegjenvundne, flytende hydrokarboner kan kombineres med enten den kondenserte del av toppdampen eller en del av totalt kondensert toppdamp som deretter oppvarmes.There is disclosed a process for liquefying natural gas and recovering components heavier than methane, where natural gas is cooled and separated in a first distillation column to a vapor enriched in methane and a bottom stream enriched in components heavier than methane, where the first distillation column uses a liquefied methane containing. reflux flow. This reflux stream can be provided by a condensed portion of the peak vapor or a portion of total condensed peak vapor which is then heated. The bottom stream may be separated into one or more additional distillation columns to yield one or more additional product streams, each of which is wholly or partially deducted as recycled hydrocarbons. A stream of non-recovered liquid hydrocarbons can be combined with either the condensed portion of the top steam or a portion of the total condensed top steam which is then heated.
