Advantages of PSA Molecular Sieve Pressure Swing Adsorption for Oxygen Production

In industry, there are three main methods for oxygen production, namely cryogenic distillation, adsorption and electrolysis, and they all use different gas separation principles; cryogenic distillation is to first liquefy air at low temperature, and then separate oxygen and nitrogen by utilizing their different boiling points. Electrolysis is the process of putting direct current into water to separate oxygen and hydrogen.

The Technical Characteristics of PSA Molecular Sieve

The pressure swing adsorption method was launched in the late 1950s. It uses zeolite molecular sieves as adsorbents to adsorb and release nitrogen from the air through pressure adsorption and depressurization, thus separating oxygen. After decades of continuous development, this technology has become very mature, with the following characteristics:

• Oxygen can be separated from the air source at room temperature.

• Gas separation cost is low, mainly electricity consumption, and the electricity consumption for unit oxygen production is relatively low.

• PSA molecular sieve can be reused, and its service life is usually 8-10 years.

• Raw materials come from the air, which is environmentally friendly and efficient, without cost.

• It can produce very high purity oxygen to meet various oxygen needs.

• Oxygen can be produced and taken at any time, and the equipment can be easily started and stopped with fast oxygen production.

• The equipment has a simple structure, easy operation, high degree of automation, and can operate without personnel.

• The construction cost of the equipment system is relatively low, and the maintenance cost is low.

It is precisely because the PSA molecular sieve pressure swing adsorption oxygen production technology has these advantages that it has a high cost performance ratio in the field of small and medium-scale oxygen production applications, and it is favored by more and more domestic and foreign oxygen-using enterprises, making it an ideal choice for small and medium-sized oxygen production and oxygen-using enterprises.
