Cold Rolled Sheets N2 PSA Nitrogen Generator for Galvanization Line Annealing System

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 Generation 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 generation 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.

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.

What is the service life of Carbon molecular sieves(CMS)

Usually, for normally 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 6 to 8 months.
