What are the main sources of hydrogen production in refineries nowadays?
Traditional refineries produce hydrogen using refinery gas, while modern refineries (newly built or upgraded) basically use coal to produce hydrogen, namely through POX units.
Hydrogen recovery from reforming hydrogen, synthetic ammonia, and dry gas
Can PSA hydrogen production meet the large-scale hydrogenation needs of refineries?
Reforming hydrogen, ethylene hydrogen, hydrogen from hydrodesulfurization off-gases – even with these sources of hydrogen, it is still not sufficient; coal-based hydrogen is needed as a supplement
Hydrogen production from dry gas and natural gas; Hydrogen production from coal; Hydrogen production from methanol
Hydrogen production from dry gas and natural gas; Hydrogen production from coal; Hydrogen production from methanol
PSA only extracts hydrogen from refinery gas, and this amount is not sufficient; coal-based hydrogen production is needed as a supplement
Catalytic dry gas or coking dry gas or natural gas
