Primary Reformer
Primary reformers are used to convert a “process gas”mixture of hydro carbons & steam into hydrogen‐rich gases which can be used in the manufacture of ammonia. The process gas is passed under pressure through vertical tubes filled with catalyst and, since high temperature(900‐950 OC) is required to maintain the required chemical reaction, the outside of the tubes are heated by burners in a large furnace.
