Product Description

Membrane N2 generation system

 

1. Operational Principle

The dried and cleaned compressed air is fed into one or more membrane modules, each of which is composed of several millions of the hollow fiber. The diameter of each fiber is as long as the hair of human being. Various gases in the air (78% nitrogen, 21% oxygen and 1% Argon) have their different permeation rate when they pass through the wall of the membrane. Therefore, oxygen, water vapor and argon etc. which is under the effect of pressured air flow, permeates fast through the wall of the membrane then dried nitrogen may be produced. Nitrogen from the terminal of the membrane is sent to the using point.

 

2. Typical application

Nitrogen is used in steel making converter & roof of blast furnace as sealing gas and in Converter pulverized coal injection, continuous casting, rolling, steel annealing, stress elimination, aging, quenching heating, carburization, nitrocarburizing, vacuum hardening etc. as heat treatment gas resource. Nitrogen is used in welding and powder metallurgy sintering process as protective gas as well as cleaning and diluting gas.

 

3. Specification

4. Main features

· Selecting the membrane with the maximum efficiency according to the requirement of the user.

· The optimum temperature control depending on the flow rate and the purity of the gas so as to keep the membrane modular for a longest working life. 

· Automatic, safe and reliable

 

5.Advantages of PSA Nitrogen Generators produced by Suzhou Purification Group

Compared with nitrogen generator produced abroad, such machine produced by Suzhou Purification Group has combined those advantages of products produced in Japan, German and America, boasting a high performance-price ratio.

The product purity may be adjusted through the change of flow rate;

It economically consumes the energy in either low pressure or normal pressure;

The equipment is simple in structure and may be conveniently maintained;

It’s controlled by a computer, practicing automatic operation.
