| description | Installation pour le traitement par perméation membranaire d'un flux gazeux d'alimentation comprenant au moins du méthane et du dioxyde de carbone, ladite installation comprenant: une première unité de séparation par membrane apte à recevoir le flux gazeux d'alimentation et à fournir un premier perméat et un premier rétentat, une seconde unité de séparation par membrane apte à recevoir le premier rétentat et à fournir un second perméat et un second rétentat, un compresseur permettant de comprimer le premier perméat à une pression comprise entre 17 bar et 25 bar, un moyen permettant de refroidir le premier perméat comprimé à une température inférieure à -40°C, une colonne de distillation permettant de séparer le premier perméat refroidi en un flux gazeux et un flux liquide, et au moins un moyen permettant de recycler le flux gazeux sortant de la colonne de distillation à l'entrée de la première unité de séparation membranaire.
Disclosed are a facility and a method using the facility for treating a feed gas stream comprising at least methane and carbon dioxide by membrane permeation, the facility comprising: -a first membrane separation unit capable of receiving the feed gas stream and providing a first permeate and a first retentate, -a second membrane separation unit capable of receiving the first retentate and providing a second permeate and a second retentate, -a compressor for compressing the first permeate to a pressure of between 17 bar and 25 bar, -a means for cooling the first compressed permeate to a temperature lower than −40° C., -a distillation column for separating the first cooled permeate into a gas stream and a liquid stream, -at least one means for recycling the gas stream exiting the distillation column to the inlet of the first membrane separation unit, -a means for measuring the concentration of methane and/or carbon dioxide in the gas stream exiting the distillation column, -a means for comparing the concentration of methane and/or carbon dioxide measured by the measurement means with a target value, and -a means for adjusting the pressure and/or the temperature of the first permeate depending on the comparison carried out by the comparison means. |
