Large N2 Gas Generator / Psa Nitrogen Gas Plant For Pharmaceutical Industry

PSA Nitrogen Gas Producer used in pharmaceutical industry

PSA Nitrogen Generator

Working principle of PSA nitrogen Generator:

Pressure swing adsorption nitrogen production device is a new type of air separation equipment, with compressed air as the raw material and carbon molecular sieve as the adsorbent.Using PSA process under the normal temperature and low pressure, the pressure swing adsorption (PSA) oxygen and nitrogen in carbon molecular sieve using the air diffusion rate is different, through the programmable controller control valve opening and closing, realize the pressure adsorption and vacuum stripping process, complete separation oxygen, nitrogen, get high purity nitrogen, nitrogen purity and gas production rate can be adjusted according to the customers' needs.

Our company produces the ordinary nitrogen type nitrogen making device, nitrogen purity is 98 ~ 99.99%, nitrogen production volume is 5 ~ 1000 Nm3 / h, the ordinary nitrogen type nitrogen making device with nitrogen gas purification device becomes a high purity nitrogen type of nitrogen making system, nitrogen purity can reach to 99.9995%, the oxygen levels in the nitrogen is less than or equal to 5 PPM, dew point less than or equal to - 60 ℃.

Composition of PSA nitrogen making machine:

  • Compressed air purification system:Carbon molecular sieve is the key material to determine the production capacity of nitrogen machine. Since the compressed air provided by air compressor usually contains oil and water, oil and water will reduce the adsorption capacity of carbon molecular sieve, so the compressed air needs to remove oil and water before entering the oxygen and nitrogen separation system. Firstly, the air is compressed by the compressor to be 0.75-1.0 MPa and enter air purification system, the pipeline filter will remove most of the water, oil and mechanical impurities, and then the freeze drying machine dewaters by cooling and make the pressure dew point to be 2 ℃ to 10 ℃, furthermore, the air is processed by the precision filter, super precision filter and activated carbon degreaser, the air with pressure 0.75-1.0 MPa, pressure dew point with 2 ℃ to 10 ℃, and the oil content less clean 0.01 PPm will be got. Compressed air purification system is composed of pipeline filter, freeze-drying machine, fine filter, ultra-fine filter, activated carbon deoiler, automatic sewage valve, ball valve and so on.
  • Air tank system: The purpose of the air storage tank system is to ensure the stability of the gas used in the oxygen and nitrogen separation system. When the oxygen and nitrogen separation system is switched, it can prevent the instantaneous airflow velocity from going too fast, affect the air purification effect, improve the quality of compressed air entering the adsorber, and help to extend the life of the molecular sieve.Air tank system consists of air tank, protective valve, globe valve, ball valve, pressure gauge, etc.
  • Body of Nitrogen making machine:Oxygen and nitrogen separation system is the core part of air separation. Its main body is two adsorption towers filled with carbon molecular sieve. When the clean compressed air enters the adsorption tower, oxygen, carbon dioxide and trace water are absorbed by the carbon molecular sieve, and nitrogen is output from the outlet end. When nitrogen is adsorbed in one column, oxygen, carbon dioxide and water adsorbed in the molecular sieve can be discharged from the pores by decompression in the other column to achieve biodesorption of the molecular sieve.The two columns adsorb and regenerate alternately and continuously output nitrogen.The main body of nitrogen making machine is composed of adsorption tower, carbon molecular sieve filled in the tower, pneumatic valve, muffler, throttle valve, compression cylinder, pressure gauge and so on.
  • Nitrogen buffer system : The main function of nitrogen buffer system is to balance the pressure and purity of nitrogen separated from the main body of nitrogen making machine and ensure the continuous supply of nitrogen.At the same time, when the adsorption tower is transformed from regeneration to adsorption, it will recharge the partially qualified nitrogen stored in the adsorption tower to protect the molecular sieve bed, and also help the adsorption tower boost pressure.At the same time, when the adsorption tower is regenerative to adsorption, it will recharge the partially qualified nitrogen stored in the protective bed of the adsorption tower, and also help the adsorption tower boosting pressure. Nitrogen buffer system consists of buffer tank, flow meter, dust filter, pressure regulating valve, throttle valve, protective valve, etc.
  • Electrical Control System :The main functions of the electrical control system are equipment start and stop operation, working status indicator light display, fault sound-light alarm indication, purity display and drive pneumatic valve according to the set program.The electrical control system is composed of programmable controller, air source triplex, solenoid valve, indicator light, micro oxygen meter, etc. It is mainly installed in the electric control cabinet.

Product Features:

  • Low cost: the advanced PSA process is a simple nitrogen production method. Nitrogen is generated within a few minutes after starting up, with low energy consumption. The cost of nitrogen is lower than that of cryogenic air separation nitrogen production.
  • Reliable performance: imported microcomputer control, automatic operation, no special training operators, just press the start switch, can automatically operate, to achieve continuous production of nitrogen.Nitrogen purity is stable and is monitored and displayed by the instrument to ensure the required nitrogen purity.
  • Excellent imported carbon molecular sieve: it has the characteristics of large adsorption capacity, high compression resistance and long service life.
  • High quality control valve: excellent imported special pneumatic valve can ensure the stable and reliable operation of nitrogen production equipment.Strong technical force and excellent after-sales service.Equipment is containerized, and only gas source, power source and water source need to be connected during field installation.Excellent electrical and mechanical assembly technology, provide continuous technical service, be responsible for site commissioning and training operation.
  • Fast start-up speed, 15-30 minutes to provide qualified nitrogen.
  • Fully automatic operation of the equipment, the whole process can be realized unattended.
  • High efficiency molecular sieve filling, more compact, more solid, longer service life.
  • Stable and adjustable pressure, purity and flow to meet different needs of customers.
  • Reasonable structure, advanced process, safe and stable, low energy consumption, compared with bottled nitrogen, liquid nitrogen operation of high cost, nitrogen production mechanism to take the lowest cost of nitrogen, for long-term engaged in food, chemical products, hardware products, pharmaceutical products and other production and processing enterprises, the use of nitrogen machine is the most cost-effective.

Main Application Fields: PSA Nitrogen Generator widely used in Electronic industry, metallurgy industry, petrochemical industry, food industry, pharmaceutical industry, chemical fiber industry, heat treatment industry, rubber tires etc.
