Box PSA Nitrogen Generator

Description

A PSA (Pressure Swing Adsorption) Nitrogen Generator is a system that produces nitrogen gas by utilizing adsorption principles. It consists of several components, including the compressed air system, pressure swing adsorption nitrogen making system, adsorbing material, and the PSA N2 making process. Here's a description of each component:

Compressed Air System:
The compressed air system supplies the primary source of air required for the nitrogen generation process. It typically includes an air compressor, filters, and a dryer to remove moisture and impurities from the incoming air.

Pressure Swing Adsorption Nitrogen Making System:
The heart of the PSA Nitrogen Generator is the pressure swing adsorption system. It consists of two or more adsorption vessels filled with adsorbing material, such as carbon molecular sieve (CMS) or zeolite. The vessels are equipped with inlet and outlet valves to control the flow of air and nitrogen.

Adsorbing Material:
The adsorbing material, often carbon molecular sieve (CMS), is selected for its ability to selectively adsorb oxygen and other impurities while allowing nitrogen to pass through. This material has a high affinity for oxygen, enabling efficient separation of nitrogen from the compressed air stream.

PSA N2 Making Process:

Adsorption Phase: Compressed air enters one of the adsorption vessels under high pressure. Oxygen and impurities are preferentially adsorbed by the adsorbing material, while nitrogen passes through and exits the vessel as the nitrogen-rich product.

Desorption Phase: Once the adsorption vessel becomes saturated with oxygen and impurities, the pressure is reduced or released. This desorption phase allows the adsorbed oxygen and impurities to be released from the adsorbing material.

Purge Phase: During the desorption phase, a portion of the previously produced nitrogen is redirected to the other adsorption vessel. This nitrogen stream purges the desorbed oxygen and impurities, carrying them out of the system.

Cycle Switching: The adsorption and desorption phases alternate between the adsorption vessels to maintain a continuous nitrogen production. The cycle switching is controlled by valves and a control system, ensuring efficient utilization of the adsorption material and consistent nitrogen output.

By utilizing the pressure swing adsorption process, a PSA Nitrogen Generator can produce high-purity nitrogen gas by selectively adsorbing oxygen and impurities from the compressed air stream. This nitrogen gas finds applications in various industries, including chemical, pharmaceutical, electronics, and food processing, where an on-site and reliable nitrogen supply is required.
