In the primary reaction, H 2 S in the inlet gas stream reacts with the iron oxide (Fe x O y) in the media to form iron-sulfur compounds (Fe x O y), free sulfur and water. Oxygen present in the gas stream further reacts with the iron-sulfur compound liberating the sulfur and re-forming the iron oxide, making it available once again for the ...

During the handling of DRI products, breakage and spillage can account for significant losses of product. Handling losses can exceed the impact of total iron content or gangue content on the total yield from iron ore to liquid steel. However, handling losses often are absorbed by different operating areas and are not accounted for in total.

— Wet scrubber designs include spray tower, tray-type, and packed-bed scrubbers, which are generally referred to as low-energy scrubbers. Packed bed scrubbers are commonly used for gas absorption. This type of scrubber spreads the liquid over packing material in order to provide a large surface area for liquid/gas interaction.
