N-GEN generator

The N-GEN is a PSA nitrogen generator for industrial applications: a carbon molecular sieve removes the oxygen from compressed air, and the alternating operation of two columns gives a continuous flow of nitrogen with a purity up to 99.999% and capacities up to 10,000 m³/h.

The generator is sized to the plant’s actual nitrogen consumption — production is most economical when the unit runs at or close to full consumption capacity.

The higher the purity specified, the more compressed air is used per cubic metre of nitrogen. Purity should therefore be set to the process’s actual requirement, not with a margin — the difference between 99.5% and 99.99% can mean twice the air consumption.

Air treatment is planned together with the generator: filtration and drying to suit the technology, as well as a nitrogen receiver to cover the process’s peak demand.
