What are the requirements of PSA nitrogen making machine for air compressor

The pressure swing adsorption nitrogen making machine is an adsorption separation technology. It has a high purity of a new gas product, can work at room temperature is not high, under the pressure of energy economy, simple equipment, operation, easy maintenance, continuous operation, can fully meet the automation. Pressure swing adsorption nitrogen making machine is designed and manufactured according to nitrogen swing adsorption technology. Two adsorption towers are usually used in parallel, and the automatic control system strictly controls the time according to specific procedures, pressure swing adsorption, decompression and regeneration, to complete the separation of nitrogen and oxygen, and obtain the required high purity nitrogen. Filling technology and front end pressure swing adsorption nitrogen maker China's unique molecular sieve perfect design features in natural gas production is simultaneously nitrogen concentration saving power consumption, the lowest operating costs. The international best performance of molecular sieves, unique combination of gas distribution and specific processes to maximize energy efficiency of molecular sieves, nitrogen recovery rate for the best carbon sieves adsorption rate of oxygen and nitrogen based on different preferential adsorption of oxygen, carbon sieves to produce nitrogen, while the most abundant unadsorbed phase.

At present, the main raw material on the PSA nitrogen machine market is high-quality compressed air, of course, compressed air, air compressors, and now the world's three major brands: American Shouli air compressor, Atlas, Ingersoll Rand, of course, match and these big brands, is a good choice, (of course, cost and other considerations, you can also choose other brands), the choice of air compressor is good, mainly because the compressed air of the nitrogen machine may be an outrageous requirement: First, the oil content in the compressed air must be less than 0.003ppm, the outlet pressure of the compressed air must be controlled at 0.75MPa to 1.2MPa, the compressed air from the pressure loss process of the air compressor system to make the nitrogen system, so the air compressor generally supports 0.8MPa, because the working principle of the nitrogen machine is pressure shift adsorption. So the pressure of the air compressor is very important, which determines the quality of nitrogen, but it does not mean that: The greater the pressure, the better, to 1.2MPa pressure, will lead to molecular sieve crushing, so it must be less than 1.2MPa, usually the best choice for screw air compressors, piston compressor outlet temperature is high, high oil content, which will directly affect the service life of molecular sieve, and air treatment equipment relatively frequent replacement of filter elements, Three imported brands of imported air compressors are generally controlled at less than 3ppm oil content, high domestic air compressor oil content, high outlet temperature, generally with activated carbon filters and oil, or molecular sieve with reduced service life, molecular sieve nitrogen machine import market prices are generally more expensive, if taking into account maintenance costs and prices, the best choice of imported screw air compressors, But for small cubic nitrogen machines, you can choose domestic air compressors.

However, in fact, it must be clear that the quality of compressed air has higher requirements for nitrogen molecular sieve, and the configuration of the nitrogen machine carefully listens to the opinions of the manufacturer to achieve a reasonable configuration.
