PSA nitrogen production system
It is primarily composed of an air compressor and an air buffer tank. The compressed air provided by the air compressor is first directed into the compressed air purification system. The purpose of the air tank system is to ensure a steady supply of air to the oxygen-nitrogen separation system and prevent excessively rapid airflow during transitions in the oxygen-nitrogen separation system, which could affect the efficiency of air purification. This, in turn, enhances the quality of compressed air entering the adsorber and extends the lifespan of the molecular sieve.
The compressed air purification system consists of a high-efficiency oil remover, a refrigerated air dryer, an activated carbon filter, and a precision filter. Compressed air passes through the mentioned equipment to remove oil, water, and dust and undergoes deep purification by the subsequent precision filter.
The PSA (Pressure Swing Adsorption) adsorption system consists of an air process tank, adsorption towers, pneumatic valves, a PLC controller, and compression devices, among other components. The adsorption system is the core part of the nitrogen generation unit, with its main components being two adsorption towers filled with carbon molecular sieves. When clean compressed air enters one of the adsorption towers, O2, CO2, and trace amounts of H2O are adsorbed by the carbon molecular sieve, while nitrogen is output from the exit as the product nitrogen gas.
When one tower is in the adsorption phase, the other tower undergoes depressurization to release the adsorbed O2, CO2, and H2O from the molecular sieve’s micropores, achieving the regeneration and desorption of the molecular sieve. The two towers alternate between adsorption and regeneration phases, ensuring a continuous output of nitrogen gas.
The unadsorbed nitrogen gas passes through the adsorption bed and flows into the nitrogen storage tank via the left inlet valve and the nitrogen generation valve. Once the left adsorption process is completed, adsorption towers A and B are connected through upper and lower pressure balance valves to equalize the pressure in both A and B adsorption towers.
This process is referred to as pressure equalization. After pressure equalization, compressed air enters adsorption tower B through the right inlet valve, and oxygen molecules in the compressed air are adsorbed by the carbon molecular sieve. The concentrated nitrogen gas then flows into the nitrogen storage tank through the right inlet valve and the nitrogen generation valve.
