Technical advantages of PSA molecular sieve pressure swing adsorption oxygen production

Release Date: 2021-10-15

There are three main oxygen production methods in industry, namely cryogenic distillation separation method, adsorption method and electrolysis method. They use different gas separation principles; cryogenic distillation separation method is to first liquefy air at low temperature. Then, using the different boiling points of oxygen and nitrogen, they are separated into oxygen and nitrogen. The law of electrolysis is to put a direct current in the water, and through electrolysis, oxygen and hydrogen are separated.
The pressure swing adsorption method was introduced in the late 1950s. It uses zeolite molecular sieve as the adsorbent, and uses the principle of pressure adsorption and decompression desorption to adsorb and release nitrogen from the air, thereby separating oxygen. After decades of continuous development, this technology is now very mature and has the following characteristics:
1. Oxygen can be separated from the air source at room temperature.
2. The cost of gas separation is low, mainly power consumption, and the power consumption per unit of producing oxygen is relatively low.
3. The molecular sieve can be used repeatedly, and the service life is usually 8-10 years.
4. The production raw materials come from air, which is environmentally friendly and efficient, and the raw materials are cost-free.
5. It can produce high oxygen purity to meet various oxygen demand.
6. Oxygen can be taken at any time, the equipment can be started and stopped conveniently, and the gas can be produced quickly.
7. The equipment is simple in structure, easy to operate, highly automated, and can be operated unmanned.
8. The construction cost of the equipment system is relatively low. Low maintenance costs.
It is precisely because of the advantages of PSA molecular sieve pressure swing adsorption oxygen production technology that it has a high cost performance in the field of small and medium-sized oxygen production applications. It is also favored by more and more domestic and foreign oxygen companies. It is a small and medium-sized oxygen production company. The ideal choice.
