Reliable Oxygen Removal for High-Purity Gases
The Copper De-Oxo System by Harsiddhi Air Solution is a state-of-the-art oxygen removal technology for hydrogen, nitrogen, and inert gases by catalytically amending residual oxygen. By utilizing a copper-based catalyst, the Copper De-Oxo ensures ultra-high purity gas fits for industrial, pharmaceutical, and electronic manufacturers.
With precision build and decades of gas handling experience, our Copper De-Oxo Units provide a stable, safe, and energy-efficient option for long life operations, operating consistently with high purity gases through less demanding gas processing in essential operations.
What is a Copper De-Oxo System?
- A Copper De-Oxo System is a catalytic gas purification unit designed to remove oxygen from gas mixtures, most commonly used in hydrogen and nitrogen-based systems.
- It works by catalytic oxidation, where copper is the reactive medium converting the oxygen to water vapor, which is removed through a drying system (such as a heatless desiccant air dryer or refrigerated dryer).
- This allows for a final gas output to be either a result of almost no oxygen — typically < 1 ppm, and is suitable for industries requiring gas purity and relicability.
How the Copper De-Oxo Unit Works
- Gas Intake: The gas composition, which contains some trace oxygen, is introduced into a reactor vessel that contains a copper catalyst.
Catalytic Reaction: Oxygen will react with copper and transform it into copper oxide (CuO). Hence, oxygen is removed from the gas stream. - Regeneration Cycle: When copper becomes oxidized it is regenerated by passing hydrogen over the copper oxide, which converts it back into copper, yielding water vapor.
- Moisture Removal: The water vapor is removed through a gas drying process, producing a gas that is completely dry and free of oxygen.
Features and Advantages of Copper De-Oxo
- High Efficiency Oxygen Removal: Capable of lowering oxygen levels to below 1 ppm.
- Regenerable Catalyst: Copper catalyst can be re-used for an extended period of time and minimized replacement costs.
- Energy Efficient Conditions to Operate: Works at moderate temperatures with low energy input.
- Safe and Stable Process Conditions: Non-explosive reaction allows for safe operations under industrial environments.
- Compact and Modular: Easy to install and integrate with PSA gas generation systems.
- Long Service Life: Rugged design and high-quality materials ensure a reliable piece of equipment.
- Low Maintenance Requirements: An automated regeneration system that minimizes downtime.
- Custom Engineered: Designed to meet individual gas flow and purity requirements.
