KDON-3200/3200/80 Oxygen plant (cryogenic air separation)

Oxygen plant

KDON-3200/3200/80 Oxygen plant (cryogenic air separation) includes seven units, such as Power system, purification system, refrigeration system, heat exchange system, distillation system, transmission system, control system.

Process Overview

1. Air compressors: The air is compressed to 0.5Mpa-0.7Mpa by the air compressor.
2. Pre-cooling: The air in the pre-cooling unit is pre-cooled to 5°C -10°C, and the water is separated.
3. Purification: The remaining water, carbon dioxide and hydrocarbons in the air are removed from the purified air of the molecular sieve.
4. Air expansion: The air undergoes expansion refrigeration in the expander to provide the cooling capacity required by the device.
5. Heat exchanger: the aluminum plate fin heat exchanger has light weight and high heat transfer efficiency.

6. Sub-cooling: Liquid air and liquid nitrogen are cooled by the nitrogen and impure nitrogen in the sub cooler.
7. Distillation: the air is subjected to distillation separation in the lower tower, product nitrogen is obtained in the upper tower, and product oxygen is obtained at the bottom of the upper tower.
