Understanding High Purity Oxygen and Nitrogen

Oxygen and nitrogen are both vital gases for industrial and commercial use. However, for many applications, the purity of these gases is of utmost importance. High purity oxygen and nitrogen refer to gases that have been separated from air and processed to remove impurities, such as carbon dioxide, moisture, and other trace gases.

  • High Purity Oxygen: Oxygen with purity levels greater than 95% is considered high purity oxygen. Depending on the application, oxygen purity can go up to 99.99%, which is required in industries such as healthcare, electronics, and metal cutting.
  • High Purity Nitrogen: Nitrogen is a non-reactive, inert gas widely used in industries where a controlled atmosphere is needed. High purity nitrogen, typically ranging from 95% to 99.99%, is used in a variety of applications such as food packaging, electronics, pharmaceuticals, and chemical processing.

The Need for High Purity Oxygen and Nitrogen Plants

Having access to high purity oxygen and nitrogen is essential for a range of applications. For businesses and industries that require a continuous supply of these gases, an on-site High Purity Oxygen and Nitrogen Plant provides the perfect solution. These plants allow businesses to produce oxygen and nitrogen locally, reducing the dependency on external suppliers, minimizing transportation costs, and ensuring a constant supply of these gases.

Additionally, the ability to produce high purity gases on-site ensures that the gases meet strict quality standards, which is crucial for many sensitive industrial processes.

How High Purity Oxygen and Nitrogen Are Produced

The production of high purity oxygen and nitrogen involves the separation of gases from the atmosphere. The process typically involves air separation techniques, the most common being Pressure Swing Adsorption (PSA) and Cryogenic Distillation. Let’s explore both methods in detail.

1. Pressure Swing Adsorption (PSA) Technology

PSA technology is widely used in High Purity Oxygen and Nitrogen Plants due to its cost-effectiveness and energy efficiency. The PSA process works by exploiting the differences in the adsorption properties of gases in the air. Here’s how it works:

  • Air Compression: Ambient air is first compressed and fed into a PSA unit. The air is typically composed of 78% nitrogen, 21% oxygen, and trace amounts of other gases.
  • Adsorption: The compressed air is passed through adsorbent beds, such as zeolite, which selectively adsorb oxygen molecules while allowing nitrogen to pass through. The nitrogen produced in this process can have a purity ranging from 95% to 99.99%.
  • Regeneration: Once the adsorbent bed is saturated with oxygen, the pressure is reduced (hence “pressure swing”), and the adsorbent material releases the captured oxygen and other impurities, regenerating the system for the next cycle.

This method is ideal for industries requiring nitrogen or oxygen in smaller to medium quantities, as it offers flexibility, cost-efficiency, and ease of operation.

2. Cryogenic Distillation

Cryogenic distillation is another method used to produce high purity oxygen and nitrogen. It is typically used in large-scale plants where very high purity gases are required. This process involves the following steps:

  • Compression and Cooling: Ambient air is compressed and cooled to cryogenic temperatures (around -160°C). At these low temperatures, the different components of the air, such as nitrogen, oxygen, and argon, liquefy at different boiling points.
  • Separation: The liquid air is distilled to separate oxygen and nitrogen based on their boiling points. Nitrogen, with a boiling point of -196°C, is separated from oxygen, which has a boiling point of -183°C. This method produces very high purity gases, typically exceeding 99.99%.

Cryogenic distillation is ideal for large-scale operations and industries that need a constant supply of very high purity oxygen and nitrogen.
