It is very rare to find the pure form of hydrogen on earth. Hydrogen is generally found in the combination with other atoms and molecules. So, in order to separate the hydrogen from these substances, an effective purification process is required. Molecular sieve is used for generating pure hydrogen which can be further utilized in various industries.
Hydrogen generation typically involves the production of contaminants or side products that need to be removed. It includes compounds such as carbon monoxide, carbon dioxide, nitrogen, water and unreacted hydrocarbons. Hydrogen PSA takes advantage of the preferential adsorption of these components, eliminating them from the hydrogen stream to yield purified hydrogen.
Traditionally, Hydrogen PSA takes advantage of multiple sieve beds and is comprised of four phases: an adsorption phase, a depressurization phase, a regeneration phase and a repressurization phase. In the process, the impure stream of hydrogen is passed into the sieve bed where impurities are selectively adsorbed onto the molecular sieve under pressure. After the adsorption step is completed, regeneration is accomplished by depressurizing the bed which decreases the affinity of the impurities allowing them to be discarded. Further purification of the bed is achieved by purging with pure hydrogen to remove any remaining contaminants. The bed is again pressurized to repeat the adsorption process. The beds run in sync to allow continuous hydrogen generation.
