KDN type high purity nitrogen air separation equipment

Cryogenic nitrogen production can not only produce nitrogen but also liquid nitrogen, which satisfies the technological requirements that require liquid nitrogen, and can be stored in a liquid nitrogen storage tank. When there is an intermittent nitrogen load or air separation equipment minor repairs, the liquid nitrogen in the storage tank After entering the vaporizer and being heated, it is fed into the product nitrogen pipeline to satisfy the nitrogen demand of the process equipment. The operation cycle of cryogenic nitrogen production (referring to the interval between two large heatings) is generally more than one year. Therefore, cryogenic nitrogen production is generally not considered for standby. Cryogenic nitrogen production can produce nitrogen with a purity of ≧99.999%. Nitrogen purity is limited by (de dan qi _dan qi chun du shou dao) nitrogen load, the number of trays, tray efficiency and oxygen purity in the liquid air, and the adjustment range is very small. Therefore, for a set of cryogenic nitrogen production equipment, the product purity is basically certain, which is inconvenient to adjust.

The automatic compact liquid nitrogen supply station produces nitrogen from the air, which is liquefied into liquid nitrogen by the nitrogen liquefier and stored in the liquid nitrogen storage tank. The compact structure enables the continuous and convenient supply of liquid nitrogen, and can be used as a small amount of liquid nitrogen supply source in the region. Nitrogen liquefier adopts mixed working medium throttling refrigerators or four-trilling refrigerators as cold sources. The company's series of nitrogen liquefier products can provide customers with more choices, and build small nitrogen liquefaction stations for major laboratories to timely solve the use needs of liquid nitrogen.

Under a certain pressure, the diffusion rate of nitrogen and oxygen in the air on the carbon molecular sieve is quite different. In a short time, the oxygen molecules are absorbed by the carbon molecular sieve in a large amount, and the nitrogen molecules are enriched in the gas phase to achieve the separation of oxygen and nitrogen. Since the oxygen adsorption capacity of carbon molecular sieve varies significantly with pressure, reducing the pressure can desorb the oxygen molecules adsorbed by the carbon molecular sieve, so that the carbon molecular sieve can be regenerated and reused. Adopting two adsorption tower processes, one tower for adsorption and nitrogen production, one tower for desorption and regeneration, alternating cycles and continuous production of high-quality nitrogen.

The purification process using two kinds of high efficiency catalyst is hydrogenated and deoxygenated at room temperature, and then the excess hydrogen is removed (when the hydrogen content is required). After purification process, the water and impurities are deep, and the high purity nitrogen is obtained.

Compressed air by the air purification system to remove oil, water, dust and other impurities into the adsorption tower equipped with zeolite molecular sieve, nitrogen, carbon dioxide, water vapor in the air is adsorbed by molecular sieve, and oxygen due to the large diffusion rate and through the adsorbent, and achieve nitrogen and oxygen separation. When the nitrogen and other impurities adsorbed in the adsorption tower reach saturation, reduce the pressure to make the zeolite molecules desorption regeneration, can be reused. Two adsorption towers are used to circulate under the control of PLC to continuously produce high quality oxygen.
