What are the yields for hydrogen production via LNG and water vapor reforming?
Thread Content
What is the yield for the LNG and water vapor reforming hydrogen production process under normal conditions? That is, how many cubic meters of hydrogen can be produced from 1 standard cubic meter of LNG (including the LNG used for combustion?). Please give me some advice! ! ! ! ! ! ! ! ! !

First, LNG is vaporized to utilize its cooling capacity; otherwise, it would be a waste. It can be used in applications such as air separation, food preservation, and rubber crushing. Natural gas water vapor conversion is a conversion process for natural gas. Process: Steam reforming without CO2 addition, Steam reforming with CO2 addition before the furnace, Steam reforming with CO2 addition after the furnace. H2: 71.39, 68.49, 68.18; CO: 10.39, 12.30, 10.44; CO2: 9.34, 12.96, 13.39; N2: 0.45, 0.41, 0.43; CH4: 7.61, 5.54, 7.26; Ar: 0.00, 0.00, 0.00; H2O: 0.23, 0.29, 0.29. Temperature at the inlet/outlet of the first-stage furnace: °C 510/840, 510/540, 510/840. Temperature at the inlet/outlet of the second-stage furnace: °C – – –. (H2-CO2)/(CO+CO2): 3.06, 2.2, 2.3. Total natural gas consumption: Nm3/h 46645, 42530, 43821. Raw gas consumption: Nm3/h 45357, 33937, 38601. Fuel gas consumption: Nm3/h 1288, 8593, 5220
It depends on your temperature; in ammonia synthesis plants, the conversion rate generally exceeds 95%
The data you provided is for methanol synthesis, right?
