Hydrogen recovery

The recovery principle of this system comes from waste hydrogen and tail gas hydrogen. First, it is cooled, washed and dedusted, and most of the water in the waste hydrogen is condensed and then enters the Roots fan for pressurization. The waste hydrogen after pressure treatment by the fan enters the hydrogen purification unit or PSA purification unit for secondary treatment, so that the oxygen content and dew point of the gas can be reduced to the production requirements. The purified hydrogen is re-used as feed stock hydrogen.
