PSA Nitrogen device according to the user's needs may include compressed air purification systems, pressure swing adsorption systems, process control systems valves (vacuum regeneration with a vacuum pump needed), and nitrogen supply system. Four, carbon molecular sieve nitrogen conditions need to control one, pure air is compressed, purified feed air into the process of carbon molecular sieve adsorption tower 3a molecular sieve manufacturers, is necessary, because the organic particles and the atmosphere enters the adsorption column will clog microporous carbon molecular sieve, and the separation performance gradually reduce carbon molecular sieve. Shanghai Ltd. new zeolite molecular sieve type gas industry commonly; A Type: K A (3A), sodium A (4A), calcium A (5A), X type: Ca X (10X), sodium X (13X) Y type : 5a molecular sieve manufacturers, sodium Y, Y zeolite calcium absorption ability, for the purification of gas, should be saved to avoid direct exposure to the air. Should be reproduced before the molecular sieve and has longer storage time of use of the absorbent. Zeolite avoid oil and liquid water. Should be used to avoid contact with the oil and liquid water. Gas industrial production has 4a molecular sieve drying process manufacturers, air sieve plant, hydrogen, oxygen, nitrogen, argon, etc. with two parallel adsorptive dryer, a work, while the other can be regenerated. Alternating work and regeneration, in order to ensure continuous operation of the device. Dryer work at room temperature, heated to 350 ℃ under gassing regeneration. Shanghai sieve factory, a new molecular sieve (certified), zeolite molecular sieves have a new factory by Shanghai Limited. Shanghai new molecular sieve Limited (www.molsionms.com) is Shanghai's Songjiang District, elemental leaders, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. There are new leaders in the molecular sieve with the staff warmly welcome all inquiries negotiations to create new molecular sieve a better future.
