ZYN pressure swing adsorption nitrogen production equipment

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.

ZYN-C type nitrogen purification equipment

At a certain temperature, the nitrogen residue in low purity nitrogen and the carbon provided by the carbon-carrying catalyst undergo nitriding reaction: the C02 generated by C+02=C02 is removed by pressure switch adsorption process and dehydrated deeply, and the high purity nitrogen is obtained.

ZYN-H hydrogenation nitrogen purification equipment

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.

VPSA vacuum pressure swing adsorption oxygen production equipment

VPSA oxygen production system is mainly composed of blower, vacuum pump, switching valve, adsorber and oxygen balance tank. After removing dust particles through the suction inlet filter, the raw air is pressurized to 0.3-0.5barg by a Roots blower and enters one of the adsorbents. The adsorber is filled with adsorbents, in which water, carbon dioxide, and a small amount of other gas components are adsorbed by the activated alumina at the bottom of the adsorber entrance, and then nitrogen is adsorbed by the zeolite molecular sieve filled at the top of the activated alumina. The oxygen (including argon) as a non-adsorbed component is discharged from the top outlet of the adsorber as product gas to the oxygen balance tank. When the adsorber is absorbed to a certain extent, the adsorbent in it will reach a saturated state. At this time, a vacuum pump is used to vacuum the adsorber through the switching valve (opposite to the adsorption direction), and the vacuum degree is 0.65-0.75barg. The absorbed water, carbon dioxide, nitrogen and a small amount of other gas components are pumped out to the atmosphere and the adsorbent is regenerated.
