Carbon molecular sieve air separation nitrogen production principle:
Carbon molecular sieve is a carbon adsorbent with a black columnar appearance. It is a porous material composed of carbon. The pore structure model is a disordered carbon structure. Carbon molecular sieves are non-polar compounds, and their important properties are based on their microporous structure. Its ability to separate air depends on the different diffusion speeds of various gases in the pores of the carbon molecular sieve, or different adsorption forces, or both effects acting simultaneously. Under equilibrium conditions, the adsorption capacity of carbon molecular sieve for oxygen and nitrogen is quite close, but the diffusion speed of oxygen molecules through the narrow voids of the carbon sieve micropore system is much faster than that of nitrogen molecules. Performance: Enrich nitrogen in the gas phase at a time away from equilibrium conditions.
Carbon molecular sieve air separation nitrogen production device锛?/strong>
This device is generally called a PSA nitrogen generator. PSA is an adsorption and separation process without a heat source. The adsorption capacity of the carbon molecular sieve to the adsorbed components (mainly oxygen molecules) increases and increases the partial pressure. Reduced because of its reduced partial pressure. In this way, the carbon molecular sieve is adsorbed under pressure and desorbed under reduced pressure, and the adsorbed components are released to regenerate the carbon molecular sieve.
The pressure swing adsorption process cycle operation includes:
Pressure filling, gas production; pressure equalization; pressure reduction, exhaust; and then pressure filling, gas production and other working phases. According to the regeneration method of the process, it can be divided into vacuum regeneration process and atmospheric regeneration process. In two processes, the raw material air is compressed and regulated by an air compressor, and then enters a cooler and an oil removal system. After drying, it enters a carbon molecular sieve adsorption tower. The upper part of the adsorption tower excludes N2, and the oxygen adsorbed by Carbon molecular sieve is directly from the lower part Emission into the atmosphere to regenerate carbon molecular sieves.
Carbon molecular sieves require controlled conditions for nitrogen production:
1路 Pretreatment of raw air
In order to avoid the oil pores in the raw material air from blocking the pores of the carbon molecular sieve but the separation effect is greatly reduced, the raw material air needs to pass through a cooler, degreasing and drying purification systems before entering the carbon molecular sieve adsorption tower.
2路 Purity and gas production of product nitrogen
When carbon molecular sieves are used to obtain nitrogen, the purity and gas production of nitrogen can be adjusted arbitrarily according to actual needs. The decrease in gas production will increase the purity of nitrogen, and conversely, the purity of nitrogen will decrease.
3路 Equalizing time
Choosing an appropriate pressure equalization time can recover energy and reduce the impact of carbon molecular sieve in the adsorption tower, resulting in pulverization, so as to extend the service life of the carbon molecular sieve. The average pressure equalization time is 1-3 seconds.
4路 Gas production time
Selecting a suitable adsorption time can save raw material air, reduce energy consumption, reduce valve switching frequency on the nitrogen generator, improve the stability of the device, and extend the service life of the carbon molecular sieve. Generally, the adsorption time is 49-90 seconds.
5路 Operating pressure
High adsorption pressure and large adsorption capacity. Therefore, pressure adsorption is advantageous, but the adsorption pressure is too high, and the air energy consumption and device requirements are also high. Therefore, the adsorption pressure needs to be selected from the perspective of comprehensive energy consumption. It is suggested that the adsorption pressure of the normal atmospheric regeneration process should be 0.6-0.8MPa.
6路 Using temperature
Because the adsorption process has an exothermic effect, the adsorption temperature will increase, and the adsorption capacity will decrease. Therefore, choosing a lower adsorption temperature is beneficial to the performance of molecular sieve nitrogen production.
