Process flow of PSA nitrogen making machine

Product Category：

PSA nitrogen making machine manufacturers tell you that PSA is a new gas separation technology, which has been rapidly developed abroad since the late 1960s and early 1970s. The mixture is separated, it uses air as the raw material, and uses a high-efficiency, high-selectivity solid adsorbent to selectively adsorb nitrogen and oxygen to separate nitrogen and oxygen in the air.

The PSA nitrogen making machine manufacturer tells you that the air enters the air compressor after removing dust and mechanical impurities through the air filter, compresses to the required pressure, and undergoes strict oil removal, water removal, dust removal and purification treatment, and outputs clean compressed air. The purpose is to To ensure the service life of the molecular sieve in the adsorption tower. There are two adsorption towers equipped with carbon molecular sieves. When one tower is working, the other tower is decompressed and desorbed. The clean air enters the working adsorption tower, and when it passes through the molecular sieve, oxygen, carbon dioxide and water are adsorbed by it, and the gas flowing to the outlet end is nitrogen and trace amounts of argon and oxygen. Another tower (desorption tower) desorbs the adsorbed oxygen, carbon dioxide and water from the pores of the molecular sieve and discharges them into the atmosphere. The manufacturer of PSA nitrogen making machine tells you that the two towers take turns to complete the separation of nitrogen and oxygen and continuously output nitrogen. The purity of nitrogen produced by pressure swing adsorption is 95%-99.9%. If higher purity nitrogen is required, nitrogen purification equipment should be added. The manufacturer of PSA nitrogen making machine tells you that 95%-99.9% of the nitrogen output from the pressure swing adsorption nitrogen making machine enters the nitrogen purification equipment, and at the same time, an appropriate amount of hydrogen is added through a flow meter, and the trace amount of hydrogen and nitrogen in the deaerator of the purification equipment Oxygen undergoes a catalytic reaction to remove oxygen and then is cooled by a water condenser, dewatered by a steam-water separator, and then deeply dried by a dryer (two adsorption drying towers are used alternately: one for adsorption and drying for water removal, and the other for heating and desorption drainage), High-purity nitrogen is obtained, and the purity of nitrogen at this time can reach 99.9995%.
PSA nitrogen making machine manufacturers tell you that with the rapid development of the industry, nitrogen has been widely used in chemical, electronics, metallurgy, food, machinery and other fields, and my country's demand for nitrogen is increasing at a rate of more than 8% every year.
