PSA systems offer advantages such as quick start-up, low energy consumption, simple operation, wide load adjustment range, and easy maintenance. Since the 1980s, with the maturation of PSA-based oxygen enrichment technology, this method has become a globally preferred solution for cost-effective oxygen production in applications not requiring ultra-high purity.

I. PSA Oxygen Enrichment Technology

PSA is widely applied in:

- Non-ferrous metal smelting: Copper, zinc, lead, gold, nickel, and titanium dioxide production.

- Ferrous metal smelting: Blast furnace oxygen-enriched coal injection for ironmaking, electric arc furnace steelmaking.

- Oxygen-enriched combustion: Industrial boilers, glass kilns, aluminum electrolysis.

- Chemical synthesis: Ammonia, methanol, ethylene, and ethylene glycol production.

- Other fields: Medical applications, wastewater treatment (oxygen-enriched aeration), pulp bleaching, hydrogen peroxide production, chemical oxidation processes, ferrite cement production, refractory brick manufacturing, ozone generation, aquaculture, carbon black production, and healthcare.

II. PSA Nitrogen Generation Technology

Nitrogen, as an inert protective gas, is extensively used in grain storage pest control, fruit preservation, metallurgy, petroleum, and chemical industries. Compared to traditional cryogenic separation, PSA offers:

- High purity nitrogen output.

- Operational flexibility and automation.

- Lower capital and operating costs.

- Convenient start-up and shutdown procedures.
