The traditional method of oxygen production requires cooling air to a liquid state and then extracting oxygen through distillation, which has high investment costs and slow start-up. The VPSA oxygen plant operates under normal temperature and pressure and has the following features:
1. The cost of oxygen production is low.
2. The process flow is simple, with few equipment, a high level of automation and convenient operation.
3. It starts up quickly and can supply oxygen normally within about 10 to 15 minutes after startup. It is easy to stop and can operate intermittently.
4. The equipment has low working pressure and good safety.
5. The purity and output of the product are easy to adjust, and it has strong adaptability.
