Steam-Methane Reforming. Most hydrogen produced today in the United States is made via steam-methane reforming, a mature production process in which high-temperature steam (700Â°Câ1,000Â°C) is used to produce hydrogen from a methane source, such as natural gas.
3. The equivalent âsteamâ pressure at 280Â°F is 35 psi 4. Add 45 psi to the required pressure 5. Add 45 psi to 35 psi = 80 psi steam pressure Steam 80 psi pressure that is provided to the equipment manufacturer for design of the process heat transfer. 80 psi shall be the pressure after the steam control valve or the steam
