Applications of PSA nitrogen generator
Nitrogen is widely used throughout the industries. Plenty of applications can benefit from this kind of on-site gas generation method.
Nitrogen is used in many metal heat treatment activities like annealing, hardening, sintering. And also for welding, brazing and soldering.
In plastic injection molding nitrogen is often used as the assist gas that prevents oxidation of the plastic that leaves the mold with a clean surface finish. Nitrogen is also injected with the plastic creating air channels which results in less plastic needed without cutting the strength.
Nitrogen is used at different stages in the production, handling and packing of beverages.
Because of its inert, colorless and odorless characteristics, it is used to displace or replace the air to reduce the risk of deterioration of the properties of the end product.
Technological Process
Nitrogen generator 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.
PSA Nitrogen Generation Advantages
The gas seperation of PSA takes such advantages as different gas has different adsorbing capacity in the CMS under different pressure to separate gases. PSA Nitrogen generators 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.
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.
Delivery Details:

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.
