Principle:
Using absorbent adsorption in the same pressure is not high boiling point, low boiling point and high adsorption separately under the adsorption quantity increases adsorption components), decompression (under the adsorption quantity reduced (desorption section), the principle of gas pressure through adsorbent bed in relative to the high boiling point impurities components of hydrogen by selective adsorption, low boiling point of components and not by absorbent adsorption of hydrogen, achieve bed separation of hydrogen and impurities, then liquation under pressure adsorption of impurity desorption component to regenerate absorbent adsorption, again impurities.
This device is four adsorption tower alternating adsorption, desorption and adsorption preparation process to achieve continuous production of hydrogen. In the process of adsorption, desorption, adsorption of tower part retained by the purity hydrogen, purity hydrogen to just part of two towers desorption respectively, and wash all qualified raw material gas adsorption tower of alternating operation by pressure swing adsorption, absorption separation system all impurity, high purity hydrogen products.
