Nitrogen purification with oxygen and hydrogen control
Review purification and regeneration duties for nitrogen processes with separate oxygen and hydrogen limits.
Manufacturer reference photo · rich-china.com01Separate product and regeneration duties
A low-hydrogen product requirement does not imply a hydrogen-free regeneration process. Define product specifications and regeneration utilities separately when evaluating the route.
02Review changeover behavior
Clarify feed quality, treatment duty, buffering and reserve supply. Include quality checks during changeover and agree how off-specification gas is handled. The confirmed design determines the sequence.
03Measure the individual limits
Agree separate oxygen, hydrogen and moisture measurements, instrument ranges and sample arrangements. Include regeneration and maintenance requirements in the operating handover.
