Gas Production Equipment
The use of physical methods to separate the oxygen in the air and get nitrogen device is called nitrogen machine, nitrogen machine is mainly divided into three kinds, respectively, are Cryogenic Air Separation Plant, molecular sieve air separation (PSA) and membrane air separation method.
Nitrogen and hydrogen with a certain flow rate and purity enter the equipment together. After fully mixing in the mixer, it enters the equipment equipped with palladium catalyst deaerator, and the chemical reaction of 2H2+O2=2H2O takes place under the effect of deoxygenation catalyst to reach the purpose of deoxygenation. After deoxygenation, the water gas in nitrogen is dehydrated by the cooler, and then nitrogen continues to enter the monotone to make the nitrogen dew point reach about -60℃. The monotone is equipped with two monotones, in which one monotone absorbs monotone, and the other one regenerates the monotone that has absorbed full water gas, so as to prepare for the next cycle of adsorption operation. After monotonic nitrogen through the filter dust, the final result is high purity nitrogen. Gas seizure device performance indicators, product quality are uneven. The following is only a brief analysis of the structure and characteristics of three gas generators commonly used in the market (hydrogen generator nitrogen generator, air compressor) :
Nitrogen attack device from the principle of nitrogen is divided into: hollow fiber membrane separation method, pressure swing adsorption method, electrochemical separation method of three.
1. The nitrogen purity of hollow fiber membrane separation method is generally about 99%, the flow is planned to be 0-10 l /min, and the market price is about tens of thousands to hundreds of thousands.
2, pressure swing adsorption method of direct attack of nitrogen flow planning is wider, purity is generally 99%, the market price is about 100,000.
3, electrochemical separation method of direct attack of nitrogen flow in 0.3-0.5L/min, oxygen content can be controlled in a few PPM, gas dew point according to the adsorbent efficiency can reach -55℃.
The above is a simple introduction to the operation of PSA Nitrogen Generator. Our company has a large number of oxygen making machines. You can come and have a look if you are interested.
