A membrane nitrogen generator adapted to deliver a flow rate of nitrogen gas having a purity at least equal to P0, which contains: a) a source of compressed nitrogen containing gas having a purity lower than P0, the source having a maximum flow rate Fm1; b) a varyer connected to the source, which is adapted to vary the flow rate of the source between Fm1 and 0; c) a nitrogen membrane fed by the source which is capable of delivering a low purity nitrogen gas having a purity P1, which purity is lower than P0 at the maximum flow rate Fm1; d) a source of hig...


A process for providing nitrogen gas to a customer at a variable flow rate, but at a purity which is at least equal to P0 whatever the flow rate of said nitrogen gas, comprising the steps of providing a first source of high purity nitrogen gas having a purity which is greater than P1 P1>P0 and a second source of low purity nitrogen gas having a purity P2 which is dependant upon its flow rate, said purity being lower than P0 when its flow rate is about its maximum flow rate and greater than P0 at lower flow rates, measuring the purity P of the low purity ...
