    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.

    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.

    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.

  • Methanol Decomposition to Hydrogen

    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.

    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.
