Much of the work into the dusting attack of alloys has been carried out on nickel-and iron-based stainless systems similar to those used in reforming reactions where the phenomenon is a nuisance. The reaction is also dangerous in that it can lead... 

Operation of natural gas-based plants follows a basic sequence whose details differ among various proprietary processes (fig. 6.7) Natural gas must first be purified to remove H2S and any dust or liquid particles. Initial filtering is followed by compression to reformer pressure and preheating, and H2S sulfur is removed by absorption by zinc oxide (ZnO). The gas is then mixed with superheated steam and reformed in two stages. Primary reforming, producing a mixture of H2 and CO, is done inside alloyed stainless steel tubes packed with a nickel catalyst in most ammonia plants these tubes are placed in a furnace heated by gas (or liquid fuel) to 750-850 °C.
