James G Speight PhD, DSc, in Natural Gas (Second Edition), 2019 851 Iron sponge process An example of a hydrogen sulfide scavenger process is the iron sponge process (also called the dry box process), which is the oldest and still the most widely used batch process for sweetening of natural gas and natural gas liquids (Anerousis and Whitman, 1984) The key difference between sponge iron and pig iron is that we can produce sponge iron by direct reduction of iron ore through reducing agents whereas the production of pig iron is by melting iron ore with charcoal and limestone at very high pressures Sponge iron and pig iron are different forms of iron that we can produce from iron Difference Between Sponge Iron and Pig Iron DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines The reduction takes place using gaseous reductants (CO + H Sponge Iron an overview ScienceDirect Topics
