I. Plateau Hypoxia: An Urgent Challenge to Address
In plateau regions above 3,000 meters above sea level, the partial pressure of oxygen in the air is merely around 70% of that in plain areas. Symptoms such as headaches, insomnia, palpitations and shortness of breath are the body's warning signs of oxygen deficiency. Long-term hypoxia may further cause irreversible damage including myocardial hypertrophy and pulmonary hypertension. For hospitals, households, enterprises and public institutions on plateaus, choosing a safe, reliable and cost-effective oxygen generation and supply system is of vital importance.
II. Comparison of Mainstream Oxygen Generation Technologies for Plateaus
There are two prevailing oxygen generation technologies: cryogenic separation and Pressure Swing Adsorption (PSA) with molecular sieves. The cryogenic process liquefies air and separates oxygen via rectification based on differences in boiling points to produce liquid oxygen. While this technology operates steadily in plain areas, it performs poorly on plateaus. Thin air and low oxygen partial pressure on plateaus drastically reduce the efficiency of cryogenic equipment and push up energy consumption. More importantly, liquid oxygen transportation on plateaus entails high risks, and any supply interruption will lead to severe consequences.
Pressure Swing Adsorption (PSA) works in an entirely different way. Operating at ambient temperature, it adopts molecular sieves to selectively adsorb nitrogen and allow oxygen to pass through, enabling on-site oxygen generation for immediate use. Highly adaptable to high altitudes and free from transportation constraints, PSA has become the mainstream choice for plateau oxygen production.
