Nitrogen production from air by membrane gas separation processes is a mature technology which is applied in numerous industrial sectors (chemical, food, aeronautics, space..). Depending on the nitrogen purity requirements (typically between 90 and 99.9%), single stage or multistage membrane process configurations are used.

The nitrogen content is calculated by subtracting the residual oxygen content from 100 %. Air is composed of nitrogen (78.1%), oxygen (20.9 %), Argon (0.9 %), CO2 (0.03 %), and some trace inert gases. Remember that the value that is normally called the nitrogen content actually is the inert gas content. Robustness Robustness of the membrane ...

It's necessary to extract nitrogen from the air so that it can be used in a purified state. 2 Methods for Achieving Nitrogen Separation from Air. To do this, air-separation plants and nitrogen generators are used. There are three methods for the separation of air components: PSA, membrane, and cryogenic systems.

Dr. Dmitri Kopeliovich Nitrogen membrane generators separate Nitrogen from Oxygen and other air components due to their selective permeability through the wall of membranes. Polymeric hollow fiber membranes with diameter of about 4 µinch (0.1 mm) are used in nitrogen generators. Principle of operation of a gas separation membrane: …

Abstract. Nitrogen, the most dominant constituent of Earth's atmosphere, is critical for the habitability and existence of life on our planet. However, its distribution between Earth's major reservoirs, which must be largely influenced by the accretion and differentiation processes during its formative years, is poorly known.

One of the significant advantages of using nitrogen membrane units is their ability to provide high-purity nitrogen gas. These units can achieve nitrogen purity levels as high as 99.5%, making them ideal for various industries such as oil and gas, chemical, and food and beverage. With nitrogen membrane units, companies can eliminate the …

Separation of air into oxygen and nitrogen is an important process, and this separation process has been applied in an industrial scale such as oxygen (O 2) enrichment from air (medical devices) and nitrogen (N 2) enrichment from air (used as protecting atmosphere for oxygen-sensitive compounds) (Jeazet et al. 2012).There are …

Biological nitrification required HRT > 10 h to decrease the NH 4 +-N concentration to below 5.0 mg/L (Fig.1 a), and low temperature further increased the required HRT because it slowed down activities of nitrifiers (Li et al., 2018b).IE by ion exchangers after cyclic NH 4 +-N exchange and regeneration also had efficient NH 4 +-N …
