When the hydrogen produced by the ammonia decomposition hydrogen production equipment is qualified, it will enter the hydrogen purification for further purification treatment. The purity of the cracked hydrogen is very high, and the volatile impurities are only traces of residual ammonia and water. It can be seen that only trace residual ammonia and water need to be removed. high-purity gas can be obtained. Gas purification adopts temperature swing adsorption technology.

Temperature swing adsorption (TSA) technology is a gas separation and purification process based on the different adsorption properties of gas molecules on the internal surface of the adsorbent (porous solid substance) at different temperatures. Absorbs impurity gas at room temperature, desorbs impurity gas when heated, and the surface of molecular sieve is full of micropores, which can absorb 20% of its own weight under normal temperature and pressure (water and impurities during static adsorption, but at a temperature of about 350 ℃) It can be completely regenerated and switched every 24 hours to obtain product gas with qualified purity and impurity content. The adsorption tower is alternately used in parallel with two towers, which can realize continuous gas supply.
