A nitrogen generator is a type of equipment used to produce high-purity nitrogen, and membrane nitrogen generators are one of the special types. The membrane nitrogen generator adopts a different working principle from the traditional nitrogen generator, so what are the differences between them, today Hongbo nitrogen generator will give you a brief introduction, I hope to help you.
Conventional nitrogen generators typically use molecular sieves to separate nitrogen and oxygen in the air, which is an adsorption material that selectively allows nitrogen to pass through through tiny pores, while preventing the passage of oxygen molecules. This separation process requires certain compression and purification steps to ensure the production of high-purity nitrogen.
The membrane nitrogen generator, on the other hand, uses a special semi-permeable membrane to achieve gas separation. These semipermeable membranes allow the passage of small molecule gases, such as nitrogen, but prevent the passage of large molecule gases, such as oxygen. This separation process does not require molecular sieves, thus simplifying the structure of the nitrogen generator even more.
Another difference of membrane nitrogen generators is their higher energy efficiency, with traditional nitrogen generators typically requiring a lot of energy to generate high pressure to propel the gas through a molecular sieve. In contrast, the working pressure of the membrane nitrogen generator is lower, so it consumes less energy and is more environmentally friendly.
In addition, membrane nitrogen generators are typically more compact and better suited for applications where space is limited. They do not require large molecular sieve columns and therefore take up less space.
