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.

PSA N2 generation system

 

1. Operational Principle

PSA nitrogen generation adopts carbon molecular sieve as adsorbent whose capacity of adsorbing the oxygen in air shall be larger more than of adsorbing the nitrogen in air. By means of valve opened and closed with PLC, two columns a&b can be shifted in circulation for pressured adsorption,de-pressured dis-adsorption in turn so as to separate the oxygen and nitrogen in air, thus a nitrogen gas with purity demanded can be made.

 

2. Typical application

Nitrogen is used in short-circuit, large-scale integrated circuit, color and black & white picture tubes, parts of TV sets and recorders, semiconductors manufacturing, electrical equipments as well as laser drilling and other electrical components as protective atmosphere.

 

3. Specification

·Flow: 3~5000Nm3/h

·Purity:≥95%~99.9995%

·Pressure: 0.1~0.8Mpa

·Dew point:≤-45℃

.Certification:ISO90001,CE

.Voltage: 220V/50HZ

.Warranty:1 Year

 

4. Main features

Provide the user with the maximum economic value

·The filling and compacting the molecular sieve shall be made in special method so that the larger compaction intensity and higher adsorption efficiency can be got.

·The optimal design mode for processing and structure enable the system to be in the best operation.

 

Higher reliability

·A special valve with working life up to one million times is adopted for the system working in high stability and reliability.

·The reasonable design concept and equipment operation more safely and reliably.

 

Easier in operation

Automatically recording the nitrogen preparation and easy to monitor and trace the working condition at any time.

Fully automatically operating the system,worker on duty shall not be needed during the whole processing.

 

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.
