Steam Reforming Process Summary

Application Purpose Hydrodesulphurization React organic sulphur to H2S for removal in the zinc oxide bed. Chloride removal Remove HCl from hydrocarbon feed to protect downstream catalysts from poisoning and to prevent halogen related corrosion and fouling. Sulphur removal Remove H2S from hydrocarbon feed to protect downstream catalysts from poisoning. Pre-reforming To reform heavy hydrocarbons and steam into hydrogen. Steam reforming (light duty) For reforming most natural gases, refinery offgases and pre-reformed feeds. Steam reforming (intermediate duty) Gases with significant C2 + up to LPG Steam reforming (heavy duty) Naphtha feeds High temperature shift Convert CO to CO2 for removal from the synthesis gas stream. This step also boosts the production of hydrogen. Low temperature shift Convert CO to CO2for removal from the synthesis gas stream. Methanation Removes trace amounts of carbon oxides from the hydrogen product gas. Support Materials Inert hold-down and support materials used above and below catalyst or absorbent beds.
