Nitrogen generator

Oxygen concentrator is an electrically operated medical device which provides purified oxygen. This device works by pumping indoor air into a container that separates oxygen from room air and concentrates it to provide oxygen continuously to users.

Oxygen plant is an industrial system designed to generate oxygen. It typically uses air as a feedstock and separate it from other components of air using pressure swing absorption or membrane separation techniques. Such plants are distinct from cryogenic separation plants which separate and capture all the components of air. Oxygen finds broad application in various technological processes and in almost all industry branches. The primary oxygen application is associated with its capability of sustaining burning process, and the powerful oxidant properties. Due to that, oxygen has become widely used in the metal processing, welding, cutting and brazing processes. In the chemical and petrochemical industries, as well as in the oil and gas sector oxygen is used in commercial volumes as an oxidizer in chemical reactions.

A nitrogen generator is a stationary or mobile piece of machinery used to separate nitrogen gas from atmospheric air. The vast majority of on-site nitrogen generation systems utilized in industries fall into two broad categories, Pressure Swing Absorption (PSA) nitrogen generators and Membrane nitrogen generators.

Air separation unit ASU is the key utility purveyor to several major industries, including electronics, metallurgy, petroleum refining and chemical processing. Bulk production of atmospheric gases follows the cryogenic separation route, which is energy-intensive owing to the need of compressing large volumes of air.
