Ammonia Decomposition to Hydrogen
Ammonia Decomposition
The hydrogen production of ammonia decomposition takes liquid ammonia as raw material. After vaporization, the mixed gas containing 75% hydrogen and 25% nitrogen is obtained by heating and decomposition with catalyst. Through the pressure swing adsorption, the hydrogen with 99.999% purity can be further produced.

Laser Cutting PSA Nitrogen Generator Plant
Principle of PSA Technology
PSA technology is a process for purifying gas mixture. Based on the the physical adsorption of gas molecules with the adsorbent, the process is a reversible working between two pressure states.
According to the principle that the impurity components of gas mixture have large adsorption capacity under high pressure and small adsorption capacity under low pressure. Specially, the hydrogen has less adsorption capacity whether high or low pressure. In order to get high product purity, the impurity partial pressure can be increased to adsorb as much as possible under high pressure.Desorption or regeneration of adsorbent under low pressure, impurities can be adsorbed again in the next cycle through by the minimize the residual amount of impurities on the adsorbent.

Food Processing PSA Nitrogen Generator Plant
Introduction of PSA Technology
PSA Technology is a new type of gas adsorption and separation technology. It has attracted the attention and competed in globe industry for development and research when it came out.
PSA Technology used into industrial production in the 1960s. And In the 1980s, PSA technology gained a breakthrough in industrial application to become the most popular gas adsorption and separation technology in the world unit now.
PSA technology is mainly used in oxygen & nitrogen separation, air drying, air purification and hydrogen purification. Among them, the oxygen & nitrogen separation is to get the nitrogen or oxygen through the combination of carbon molecular sieve and pressure swing adsorption.

Methanol Decomposition to Hydrogen
Methanol Decomposition
Under certain temperature and pressure, methanol and steam undergo methanol cracking reaction and carbon monoxide conversion reaction to generate hydrogen and carbon dioxide with the catalyst. This is a multi-component and multi reaction gas-solid catalytic reaction system, and the chemical equation is as follows:
CH3OH → CO +2H2(1)
H2O+CO → CO2 +H2(2)
CH3OH +H2O → CO2 +3H2(3)
Hydrogen and carbon dioxide produced by reforming reaction are separated by pressure swing adsorption (PSA) to obtain high-purity hydrogen.

Pharmaceutical PSA Oxygen Generator Plant
Process of PSA Oxygen Generator Plant
According to the principle of pressurized adsorption, depressurization and desorption， the PSA oxygen generator plant is an automatic equipment that uses zeolite molecular sieve as adsorbent to adsorb and release oxygen from the air. Zeolite molecular sieve is a spherical white granular adsorbent with micropores on the surface and inside. The micropores characteristics enable to make the O2 and N2 kinetic separation. The kinetic diameters of the two gases are slightly different. N2 molecules have a faster diffusion rate in the micropores of zeolite molecular sieve, and O2 molecules have a slower diffusion rate. The diffusion of water and CO2 in compressed air is similar to nitrogen. Finally, oxygen molecules are enriched from the adsorption tower.

Metallurgy PSA Oxygen Generator Plant
Principle of PSA Oxygen Generator Plant
There is 21% oxygen in the air. The principle of PSA oxygen generator plant is to extract oxygen to high concentration from the air by physical methods. Therefore, the product oxygen will not be doped with other harmful substances, and the oxygen quality depends on the air quality and better than air.
The main parameters of the PSA oxygen generator plant are: power consumption and oxygen production, and the oxygen production is usually reflected by the output oxygen flow and concentration. In addition, the important parameters also include: the working pressure of the PSA oxygen generator plant and the pressure of the oxygen output port.

Introduction of PSA Oxygen Generator Plant
Oxygen generator is an equipment that uses air as raw material to produce the oxygen, and the oxygen concentration can reach 95%, which can replace bottled oxygen. The principle of industrial oxygen generator plant use PSA technology. Base on the different condensation points of various components in the air, compress the air with high density to separate the gas and liquid, then distillation to obtain oxygen. Large air separation equipment is generally designed to be high, so that oxygen, nitrogen and other gases can fully replace the temperature and rectify in the process of climbing and falling. The whole system consists of compressed air purification assembly, air storage tank, oxygen and nitrogen separation device and oxygen buffer tank.

Carbon Carried Purification to Nitrogen
Principle of Carbon-Carried Purification
Carbon-carried purification can be used for processes that are sensitive to hydrogen or have difficulties in hydrogen gas source. Raw nitrogen reacts with excess carbon at high temperature to produce CO2. High purity nitrogen can be obtained after passing through the adsorption tower of decarburized oxygen compounds.

Hydrogenation Purification to Nitrogen
Principle of Hydrogenation Purification
The raw nitrogen will be produced by PSA or membrane separation, and mixed with small amount of hydrogen. Residual oxygen reacts with hydrogen to produce water vapor in a reactor filled with metal palladium catalyst, therefor, most of the water vapor is condensed through the after-cooler, and the condensed water is removed through the high-efficiency water separator. After deep dehydration and dust removal in the dryer, the high purity nitrogen is obtained finally.
By the way, The adsorption dryer can make the dew point of product gas below – 70℃. The purity of product gas continuously monitored online by analyzer.

Introduction of Membrane Separation Nitrogen Generator
Membrane Separation Nitrogen Generator uses a new technology with separation membrane as the core to separate, concentrate and purify substances. Separation membrane is a membrane with different morphological structures, which formed from organic polymers of special separation and inorganic materials.
Because of the different rates of permeation through the membrane, binary or multi component components can be separated or enriched under a certain driving force.
