Producing Nitrogen via Pressure Swing Adsorption


Pressure swing adsorption (PSA) can be a cost-effective method of onsite nitrogen generation for a wide range of purity and flow requirements.

Nitrogen gas is a staple of the chemical industry. Because it is an inert gas, nitrogen is suitable for a wide range of applications covering various aspects of chemical manufacturing, processing, handling, and shipping. Due to its low reactivity, nitrogen is an excellent blanketing and purging gas that can be used to protect valuable products from harmful contaminants. It also enables the safe storage and use of flammable compounds, and can help prevent combustible dust explosions. Nitrogen gas can be used to remove contaminants from process streams through methods such as stripping and sparging.
