METHOD FOR SEPARATING A MIXTURE CONTAINING AT LEAST NITROGEN AND METHANE
A method for separating a mixture containing at least nitrogen and methane by cryogenic distillation in a first column operating in a first pressure and a second column operating at a second pressure lower than the first pressure, the mixture being separated in the first column to form a gas enriche...

| description | A method for separating a mixture containing at least nitrogen and methane by cryogenic distillation in a first column operating in a first pressure and a second column operating at a second pressure lower than the first pressure, the mixture being separated in the first column to form a gas enriched in nitrogen and a liquid enriched in methane, at least a portion of the gas enriched in nitrogen being at least partially condensed in a heat exchanger and returned to the first column, the gas enriched in nitrogen is sent into the heat exchanger by the bottom, ascends in a first series of passages of the exchanger and condenses therein at least partially, the liquid formed descending in these passages of the first series and exiting by the bottom of the exchanger. |
