Air separation plant with the internal compression process is to cancel the oxygen (nitrogen) compressor, extract liquid oxygen from the main condensing evaporator of the rectification tower or extract liquid nitrogen from the top of the lower tower, pressurize through the liquid oxygen pump and liquid nitrogen pump, and then exchange heat between high-pressure air and liquid oxygen, liquid nitrogen, and make it vaporize out of the cold box as a pipeline product to supply gas。

※The system characteristics of the compressed air separation equipment：

1.Product purity：
The purity of oxygen is 99.7%, which meets the requirements of medical oxygen, and the purity of high purity oxygen and high purity nitrogen can be customized to 99.9995% O2 and 99.999% N2。

2.Control system：
Adopt unattended and remote control to reduce manpower cost。

3.Low power consumption：
The latest international technology adopted by our company can greatly reduce the energy consumption per unit of product gas, saving 10-25% energy consumption compared with similar products.

4.Safety economy：
The internal compression process uses liquid oxygen pump instead of oxygen compressor, which makes the complete plant safer and more economical in investment operation。

5.Small footprint：
Compact structure, small floor area, save land cost, reduce investment cost。

6.Continuous gas supply：
Strong continuous gas supply capacity, long time, can be set up at the same time the liquid backup system in case of emergency, to ensure the uninterrupted gas supply。

7.Reliability：
High reliable performance, advanced technology, less moving equipment, key components are used in the well-known first-class brands at home and abroad。

※Technical specifications：
