As the global demand for clean energy continues to grow, an advanced technology called Air Separation Units (ASU) is bringing revolutionary changes to the industrial and energy sectors. ASU provides key gas resources for various industrial applications and new energy solutions by efficiently separating oxygen and nitrogen from the air.
The working principle of ASU begins with the compression of air. In this process, air is fed into a compressor and compressed to a high pressure state. The high-pressure air then enters a heat exchanger to reduce the temperature through a cooling process to prepare for subsequent gas separation.
Next, the pretreated air enters the distillation tower. Here, oxygen and nitrogen are separated through a distillation process using the difference in boiling points of different gases. Since oxygen has a lower boiling point than nitrogen, it first escapes from the top of the distillation tower to form pure gaseous oxygen. Nitrogen is collected at the bottom of the distillation tower, also reaching a high purity.
This separated gaseous oxygen has a wide range of application prospects. Especially in oxygen-fuel combustion technology, the use of gaseous oxygen can significantly improve combustion efficiency, reduce the emission of harmful gases, and provide the possibility of more environmentally friendly energy utilization.
With the advancement of technology and the enhancement of environmental awareness, ASU plays an increasingly important role in industrial gas supply, health care, metal processing, and emerging energy storage and conversion fields. Its high efficiency and environmental protection characteristics indicate that ASU will become one of the key technologies to promote global energy transformation and industrial upgrading.
Shennan Technology will continue to pay attention to the latest developments in ASU technology and promptly convey the latest developments in this field to the public. We believe that with the continuous advancement of clean energy technology, ASU will play a more important role in the future energy revolution.
