Abstract (en)
[origin: WO2015173503A1] A process for injecting biomethane into a network which has a gross calorific value of value X between XI and X2, comprising the injection of nitrogen into the biomethane network before the injection of the biomethane into the network which has a gross calorific value of value X so as to reduce the calorific value of the biomethane network to a value between XI and X2, with the nitrogen derived from the retentate of at least one membrane stage.
