Bulk hydrogen (H2) production in a petroleum refinery by steam methane reforming utilizes high temperatures, moderate pressures and catalyst-filled tubes that generate high tube temperatures of up to 920°C (1,690°F), imposing relatively harsh performance demands on system components.
Bulk hydrogen (H2) production in a petroleum refinery by steam methane reforming utilizes high temperatures, moderate pressures and catalyst-filled tubes that generate high tube temperatures of up to 920°C (1,690°F), imposing relatively harsh performance demands on system components.
Creep rupture and high-temperature cycling place a severe service duty on the catalyst tubes, tube outlet “pigtails” and subheader collector train, leading to ruptured pigtails and cracking in weld joints of component connections.
