The chemical industry nitrogen machine is used for the production of gas and nitrogen purification of various storage tanks and pipelines in the chemical industry. The purity, flow and pressure of the chemical industry special nitrogen machine developed and produced by our company are stable and adjustable to meet the needs of different customers.

Chemical industry nitrogen machine process overview:

At present, carbon molecular sieve and zeolite molecular sieve are used more in the field of nitrogen and oxygen production. The separation of oxygen and nitrogen by molecular sieve is mainly based on the different diffusion rates of the two gases on the molecular sieve surface. Carbon molecular sieve is a carbon-based adsorbent with some characteristics of activated carbon and molecular sieve. Carbon molecular sieves are composed of very small pores with pore sizes ranging from 0.3nm to 1nm. The smaller diameter gas (oxygen) diffuses faster and enters the molecular sieve solid phase more, so that nitrogen can be enriched in the gas phase. After a period of time, the adsorption of oxygen by the molecular sieve reaches equilibrium. According to the characteristics of the adsorption amount of adsorbed gas by the carbon molecular sieve under different pressures, the pressure is reduced to remove the adsorption of oxygen by the carbon molecular sieve, which is called regeneration. The pressure swing adsorption method usually uses two towers in parallel, alternating pressure adsorption and decompression regeneration, so as to obtain a continuous flow of nitrogen.

Chemical industry nitrogen machine scope:

With air as raw material, carbon molecular sieve as adsorbent, the use of pressure swing adsorption principle, the use of carbon molecular sieve on oxygen and nitrogen selective adsorption and nitrogen separation method, commonly known as PSA nitrogen production. This method is a new nitrogen production technology developed rapidly in the 1970s. Compared with the traditional nitrogen production method, it has the characteristics of simple process, high degree of automation, fast gas production (15 ~ 30 minutes), low energy consumption, product purity can be adjusted in a large range according to the needs of users, easy operation and maintenance, low operating cost, and strong adaptability of the device, so it is very competitive in the nitrogen production equipment below 1000Nm3 / h. More and more popular with small and medium nitrogen users, PSA nitrogen has become the preferred method for small and medium nitrogen users. Its main process: air compression part: air compressor, air storage tank; Air purification: high efficiency oil remover, precision filter, compressed air dryer, air buffer tank, activated carbon filter; Nitrogen machine host part: adsorption tower, PLC controller, nitrogen dust filter, nitrogen storage tank, compressed air as raw material and power, through pressure swing adsorption to produce 95% to 99.9995% of the purity of nitrogen; Nitrogen purification part: The use of carbon purification device (hydrogenation purification device) to purify 99.9% of ordinary nitrogen, to obtain high purity nitrogen (99.999% ~ 99.9995%) The company can provide production from 3-3000Nm3/h, purity from 95% to 99.9995% of nitrogen.
