Providing a nitrogen product

The invention relates to an air separation system (100) for producing a gaseous nitrogen product by means of a low-temperature air separation, having a rectification column system (10) with a high-pressure column (11), a low-pressure column (12), and at least one additional rectification column (13,...

More Information
Summary:The invention relates to an air separation system (100) for producing a gaseous nitrogen product by means of a low-temperature air separation, having a rectification column system (10) with a high-pressure column (11), a low-pressure column (12), and at least one additional rectification column (13, 14), wherein the air separation system (100) is designed to provide the gaseous nitrogen product using a head gas formed in the low-pressure column (12); the air separation system (100) is designed to form a fluid which is enriched with oxygen and argon and is depleted of nitrogen in the low-pressure column (11) and discharge at least one part of the fluid which is enriched with oxygen and argon and is depleted of nitrogen out of the low-pressure column (12); and the air separation system (100) is designed to subject at least one part of the fluid which is enriched with oxygen and argon and is depleted of nitrogen and which is discharged from the low-pressure column (12) to a low-temperature separation, thereby us
