Introduction

Oxygen gas plants are essential for industries requiring high-purity oxygen. Understanding their operation involves examining the principles of oxygen generation, the components of the plant, and the detailed working processes.

Principles of Oxygen Generation

The generation of oxygen in industrial plants primarily involves the fractional distillation of liquid air. Fractional distillation separates atmospheric air into its primary components: oxygen (20.95%), nitrogen (78.09%), and argon (0.93%), among others. Efficiency and purity depend on precise temperature control, typically at cryogenic levels where liquid air distills at temperatures as low as -186°C.

Components of an Oxygen Gas Plant

• Air Compressor: Compresses atmospheric air to high pressure.
• Pre-Cooling System: Cools the air to around 5°C to remove moisture.
• Purification System: Removes carbon dioxide and hydrocarbons, ensuring air purity.
• Cryogenic Distillation Column: Main unit where distillation occurs, utilizing precise temperature control to separate oxygen.
• Expansion Engine: Lowers the temperature further through adiabatic expansion.
• Storage Tanks: Store pure oxygen for distribution or usage.

Working Process of an Oxygen Gas Plant

The process begins with atmospheric air being compressed using an air compressor, achieving pressures exceeding 200 kPa. The compressed air moves to a pre-cooling system that uses chillers to reduce the temperature to 5°C. After pre-cooling, the air enters a purification unit, typically employing molecular sieves or activated alumina to remove carbon dioxide and moisture.

Purified air then proceeds to the cryogenic distillation column. Here, the air is cooled further to a cryogenic state (-186°C), causing it to liquefy. The liquid air enters a high-pressure distillation column where nitrogen, being more volatile, is separated from oxygen and argon. The process utilizes reflux to refine the oxygen purity, achieving concentrations above 99.5%.

The final stage involves storing the liquefied oxygen in well-insulated tanks maintained at cryogenic temperatures for distribution or direct use.
