Title (EN) HELIUM RECOVERY FROM GASEOUS STREAMS
(FR) RÉCUPÉRATION D'HÉLIUM À PARTIR DE COURANTS GAZEUX
Abstract:
(EN) Recovering helium from a gaseous stream includes contacting an acid gas removal membrane with a gaseous stream to yield a permeate stream and a residual stream, removing a majority of the acid gas from the residual stream to yield a first acid gas stream and a helium depleted clean gas stream, removing a majority of the acid gas from the permeate stream to yield a second acid gas stream and a helium rich stream, and removing helium from the helium rich stream to yield a helium product stream and a helium depleted stream. A helium removal system for removing helium from a gaseous stream including hydrocarbon gas, acid gas, and helium includes a first processing zone including a first acid gas removal unit, a second processing zone including a second acid gas removal unit, a third processing zone, and a helium purification unit.
(FR) L'invention concerne la récupération d'hélium à partir d'un courant gazeux, consistant à mettre en contact une membrane d'élimination de gaz acide avec un courant gazeux afin de produire un courant de perméat et un courant résiduel, à éliminer une majorité du gaz acide du courant résiduel afin de produire un premier courant de gaz acide et un courant de gaz purifié pauvre en hélium, à éliminer une majorité du gaz acide du courant de perméat afin de produire un second courant de gaz acide et un courant riche en hélium, et à éliminer l'hélium du courant riche en hélium afin de produire un courant de produit hélium et un courant pauvre en hélium. Un système d'élimination d'hélium, destiné à éliminer l'hélium d'un courant gazeux comprenant un gaz hydrocarboné, un gaz acide et de l'hélium, comprend une première zone de traitement comportant une première unité d'élimination de gaz acide, une deuxième zone de traitement comportant une seconde unité d'élimination de gaz acide, une troisième zone de traitement et une unité de purification d'hélium.
