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 Pressure Swing Adsorption. Actually, PSA nitrogen gas generators are usually used in applications where the purity of nitrogen is higher than 99.5% with oxygen content is lower than 0.5%.

Technological Process

Nitrogen 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.

Advantages of PSA Nitrogen System

The gas system of PSA takes such advantages as different gas has different adsorbing capacity in the CMS under different pressure to separate gases. PSA nitrogen systems are designed based on the PSA theory. They possess the properties of simple technology, low space requirement, quick start up, simple maintenance&operation, good applicability, high automation, low operation cost, low investment, etc.

1) convenient and efficient to generate nitrogen: Advance technology, special gas flow distributor to make the gas distribute more well-distributed, high efficient use of CMS, qualified nitrogen can be offered within 15 to 30 minutes.
2) Convenient use: The equipment structure is compact, low space coverage and no need of construction investment, low investment, the only thing to do is to connect power to generate nitrogen.
3) More economical than other ways of nitrogen supply: PSA technology is a simple way to generate nitrogen. It takes air as source, and the only energy consumption is only electricity consumption. So it has the advantages of low operation cost, low energy consumption and high efficiency.
4) Electromechanical integrated design to realize automatic operation: Imported PLC control the full automation, the flow rate, pressure and purity of nitrogen can be regulated and displayed consecutively; No personnel is needed to be on duty.

Wide application scope:

Nitrogen produced by this PSA generator system can be used as the protective gas in heat treating process; Chemical industry production, nitrogen filled for purification in all kinds of storage tank and pipeline; Gas for production of rubber and plastic products; Oxygen exclusion and keeping food fresh in food industry package; Purification and blanket gas in beverage industry; Nitrogen filled for package and exclusion of oxygen for container in pharmaceuticals industry; As protective gas in the process of producing electronic component and semiconductor in electronic industry. Purity, flow rate and pressure are stable and can be regulated to satisfy the different customers'needs.
Enhancement: To ensure the better quality, the main parts such as CMS and PLC, we use world famous brand Germany BF and Japan MITSUBISHI
