Another hydrogen production route is the recovery and purification of byproduct hydrogen from chemical or petrochemical processes.
The most common chemical processes where hydrogen is recovered include (but not limited to):
- Chlorine production
- Ethylene production
- Propylene production from propane dehydrogenation (PDH)
- Refinery production off gases (meets 50% of refinery hydrogen needs)
