The purpose of the gas separation plant (ASU – Air Separation Unit) is to produce oxygen, nitrogen and argon for the plant’s internal consumption, however the high efficiency of the steel processes allows the surplus to be sold on the internal market.

The main characteristic of ASU is the high production of gases with a high level of purity, which allows a wide application in the chemical, pharmaceutical, food, metallurgical, hospital industries, etc.

Strategically located at the Master Plan of the Usina Aço Verde do Brasil Mill, the plant occupies an area of approximately 2500m², between the Steel Mill and Coil and Bar Rolling Mill processes. ASU’s production capacity is approximately 5,114 Nm³/h of oxygen, 3,234 Nm3/h of Nitrogen and 170 Nm3/h of Argon. The products can be supplied in liquid and gaseous forms in a variety of degrees of purity, as shown in the table below:
