120 NM^3 PSA Nitrogen Generation System

120 NM^3 PSA Nitrogen Generation System     Nitrogen offers a wide range of applications such as purging, firefighter, creating inert atmosphere, carrier gas, blanketing, packing, filling, plastic molding, so on and so forth. On -site nitrogen generation is a favorable choice for many manufacturers as it is an easy and reliable way for them to save money and give free control over the nitrogen gas use. Our company offers on-site nitrogen generation based on the principle of PSA,which is reliable and cost effective way to get the nitrogen for industrial usage. For higher purity nitrogen(99.999%,and 99.9995%),we offer two steps solutions:First step of PSA nitrogen generator, and the second step to purify the nitrogen to reach the required purity.

        What is PSA ? It is a  technology used to generate gaseous Nitrogen on-site. Carbon Molecular Sieve (CMS) adsorbs oxygen and water vapor molecules under high pressure - while allowing Nitrogen to pass through,so that the nitrogen is separated from the air. Skid-mounted units can be supplied according to  customer's requirements.   Technological Process

Nitrogen Generating system from our company are designed and manufactured based on the principle of Pressure Swing Adsorption(PSA). Ambient air, having being compressed and purified to remove oil, water and dust, enters the adsoption swing adsorping device with two adsorption towers filled with carcon molecular sieve(CMS). The compressed air flow to the adsorption tower from the bottom to up. In the process, oxygen molecular is adsorbed, while nitrogen flows out of the upper side of adsorption tower and then enters then buffer tank for impure nitrogen. After a period of time, the CMS in the adsorption tower is saturated by the oxygen adsorbed. At this time, regeneration is needed. It is realized by stopping adsorbing step and reduce pressure in the adsorption tower. Adsorption and regeneration are conducted alternatively in the two adsorption towers to ensure the consecutive output of nitrogen gas.   The whole system components  The whole nitrogen generating system mainly consists of the air compressor, the compressed air receiver, filters, refrigeration dryer, the PSA nitrogen generator, and the nitrogne receiving tank. For the air compressor, famous brand such as the Atlas Copco, the Ingersoll Rand can be available from our company to match the PSA nitrogen generators. For filters, the elements with brand of Hankison, Domnick are available. For refrigeration dryer, we have J.mec, the first brand within China, also Hanzhou Union Filter the professional manufacturer of dryer and filters. For the purifying system,there are several kinds of ways,namely, by hydrogenation,by carbon deoxidation, and by highly efficient- oxidation.   Enhancement:To ensure the better quality and longer service life, the main parts such as CMS and PLC, we use world famous brand Japan Takeda and MITSUBISHI, for valves, we use Germany Burkert solenoid valves and pneumatic valves.   Packaging & Shipping  Seaworthy packing and standard wooden case packing are offered according to customer's requirement.     FAQ     What is the service life of Carbon molecular sieves(CMS)   Usually, for normaly use, the life span of the CMS is about 5 to 8 years.    What is the cycle time to replace the filter element?   Usually, the filter element needs to be replaced for every 6000 hours.
