Oxyberg - oxygen generator

What is our PSA Oxygen Generator?

Our OXYBERG® PSA oxygen systems stand out due to their advanced Pressure Swing Adsorption technology, which ensures efficient and reliable oxygen production.

A PSA (Pressure Swing Adsorption) oxygen generator is an advanced technology used to separate oxygen from air, providing a high-purity oxygen supply for various applications.

This system utilizes zeolite molecular sieves to adsorb nitrogen from compressed air, allowing oxygen to pass through and be collected. The PSA process involves two vessels filled with molecular sieves that alternate between adsorption and desorption phases.

As one vessel adsorbs nitrogen, the other regenerates by releasing the adsorbed gases. This cycle ensures a continuous production of oxygen enriched air with purity levels typically ranging from 90% to 95%. PSA oxygen generators are known for their efficiency, reliability, and cost-effectiveness, making them suitable for industries such as healthcare, water treatment, and manufacturing.

By using PSA technology, these systems deliver a consistent and dependable oxygen supply, eliminating the need for external oxygen sources.

How PSA Technology Works for Oxygen and Nitrogen Generators

PSA (Pressure Swing Adsorption) technology is an advanced method used in oxygen and nitrogen generators to separate these gases from atmospheric air.

The process involves two towers filled with carbon molecular sieves (CMS) and zeolite molecular sieves. When compressed air is introduced, the molecular sieve capture nitrogen, allowing oxygen to pass through and be collected at the generator outlet.

During the high-pressure phase, the sieves adsorb nitrogen, carbon dioxide, and water vapor, producing high-purity oxygen. The system alternates between two tanks: one tank absorbs while the other regenerates by reducing pressure, releasing the adsorbed gases back into the atmosphere.

This alternating cycle ensures continuous and stable production of high-purity oxygen or nitrogen.

Key elements of PSA technology include:

  • Dual-tower System: Ensures continuous operation by alternating between adsorption and desorption phases.
  • Carbon Molecular Sieves (CMS): Capture nitrogen molecules during the adsorption phase.
  • Zeolite Molecular Sieves: Enhance the separation process for high-purity oxygen production.
  • Pressure Swing Adsorption: The process relies on pressure changes to separate and produce gases efficiently.
  • Energy Efficiency: Low energy consumption due to advanced technology and optimized operation cycles.
  • Minimal Maintenance: Designed for long-term use with minimal maintenance requirements.

FAQ – Frequently Asked Questions

What is the difference between a PSA oxygen plant and a liquid oxygen plant?

A PSA oxygen plant separates oxygen from air using molecular sieve and pressure changes, producing oxygen on-site at high purity levels.

A liquid oxygen plant, on the other hand, involves cryogenic distillation to produce liquid oxygen, which is then stored and transported.

Liquid oxygen plants can achieve higher purity levels but involve more complex infrastructure and higher operational costs.

What are the disadvantages of PSA oxygen generators?

PSA oxygen generators may have higher initial setup costs compared to traditional methods. They also require regular maintenance to ensure optimal performance and might not achieve the same purity levels as liquid oxygen plants for certain high-purity requirements.

However, PSA systems offer continuous on-site oxygen production, lower operational costs, and greater efficiency for many industrial applications.
