Air Separation Unit
Air Separation Unit
Polaris Air Separation Units (ASU) provide a flexible, customized, and innovative technical solution to produce industrial gases such as Nitrogen, Oxygen, and Argon.
The plants use cryogenic technology for air fractionation in order to have products, simultaneously or alternatively, in either gaseous or liquid form. Each unit is tailored to the customer’s individual needs, and each component is tested to meet the most stringent international standards to guarantee the highest quality. Plants are designed for flexibility with regard to products, power consumption, available time, or total production.

Examples of Specific Air Separation Units
Every aspect of our N2 Generation plants can be adapted to specific client requests and/or site needs.
- High purity of product (up to a concentration < 1 ppm of O2)
- Compact and tailor-made design to match client needs
- Possibility of liquid nitrogen production suitable as a strategic reserve to cover peak rates or as a backup in case of plant shutdown
- Liquid storage and vaporization can be integrated in plant automation for prompt reaction
- Low operating and maintenance cost
Nitrogen and Oxygen Generation
Cryogenic technology allows for the production of very high liquid oxygen production that can be used for several medical and industrial applications. Polaris plants are designed to minimize gas production cost, while taking into consideration both CAPEX and OPEX.
Liquid oxygen is produced simultaneously with nitrogen and clients can benefit from several advantages:
- High purity of oxygen product (up to medical standard)
- High process efficiency
- High flexibility with the possibility of maximizing LOX or LIN production based on market/user needs
- Possibility of LIN and LOX storage as a backup to cover peak usage rates
In addition to a LIN/LOX plant, an integrated module for Argon production can be added.
Thanks to cryogenic technology, a high purity of liquid argon can be achieved, thereby maintaining a high overall efficiency of the plant. Even though argon (Ar) is a noble gas that comprises only 0.93% of the atmospheric air, Polaris has experience with a recovery rate > 95% with < 2 ppm of O2 as impurity.
Argon is most commonly used in the welding industry as an inert atmosphere to prevent oxidation. The uses are growing in the medical and scientific research communities.
