Nitrogen Generation System

RSNGS is Risheng's premium on-site nitrogen solution, using reliable and efficient PSA technology to separate nitrogen and oxygen, producing high-quality nitrogen with high flow and high purity. Clean compressed air will flow through the adsorption vessel, which is filled with high-quality carbon molecular sieves to adsorb oxygen and other trace gases in the clean compressed air while allowing nitrogen molecules to pass freely. Dry, high-purity nitrogen is now available for a wide range of applications.

RSNGS is one of the most advanced and economical on-site nitrogen solutions on the market. Compared with multi-group modular systems, it has lower operating and maintenance costs. It is equipped with an automatic purge system when the nitrogen purity is lower than the requirement, and ensures a stable quality of nitrogen is supplied at the generator outlet.

Working Principle

The two primary technologies used in these systems are Pressure Swing Adsorption (PSA) and membrane separation.

Pressure Swing Adsorption (PSA): In a PSA system, compressed air is passed through a bed of adsorbent material, typically carbon molecular sieves (CMS). These sieves selectively adsorb oxygen and other trace gases, allowing nitrogen to pass through. The system operates in cycles, where one adsorbent bed is generating nitrogen while the other is regenerating by releasing the adsorbed gases.

Membrane Separation: In a membrane system, compressed air is passed through hollow fiber membranes that selectively allow oxygen and other gases to permeate through the membrane walls, leaving nitrogen as the primary gas in the output stream.

Solution

What is the range of nitrogen purity that a Nitrogen Generation System can produce?
Nitrogen generators can produce nitrogen with purities ranging from 90% to 99.999%, depending on the technology and configuration used. This allows the system to accommodate various applications, from general inerting to ultra-high purity requirements.

How does a Nitrogen generators ensure a continuous supply of nitrogen?
The system generates nitrogen on-demand, continuously producing nitrogen as required. This eliminates the need for storage tanks and reliance on external suppliers, ensuring a consistent and uninterrupted nitrogen supply, which is crucial for maintaining production efficiency.

What are the cost benefits of using a Nitrogen generators?
By generating nitrogen on-site, companies can significantly reduce costs associated with cylinder rentals, delivery logistics, and handling high-pressure cylinders or bulk liquid nitrogen. Over time, this leads to substantial savings and a quicker return on investment.

Can a Nitrogen Generation System be used in both small and large-scale operations?
Yes, They are available in various sizes and configurations, making them suitable for a wide range of environments. Whether for small laboratories or large industrial facilities, these systems can be easily integrated and scaled to meet increasing demand.

How energy efficient are modern Nitrogen Generation Systems?
Modern Nitrogen generators are designed with high energy efficiency, reducing overall energy consumption compared to traditional nitrogen supply methods. This not only lowers operational costs but also minimizes environmental impact.

What kind of maintenance is required for it?
These systems require minimal maintenance, with regular tasks typically involving filter changes and, in PSA systems, occasional replacement of the adsorbent material. The robust and durable components ensure high uptime and reliability.
