8.5.1 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 process was implemented during the 19th century and.
Iron Sponge Process. The iron sponge process uses the chemical reaction of ferric oxide with H2S to sweeten gas streams. This process is applied to gases with low H2S concentrations (300 ppm) operating at low to moderate pressures (50-500 psig). Carbon dioxide is not removed by this process. The reaction of H2S and ferric oxide produces water.
Nov 24, 2020 Swedish model for carbon-free sponge iron. Swedish mining and mineral group LKAB will switch from producing iron ore pellets to producing carbon-free sponge iron using hydrogen-based technology. State-owned LKAB estimates that the move will cut annual carbon dioxide emissions by 35 mln t. Under the Swedish government fossil-free Sweden.
Nov 23, 2016 Pyrite cinder is a solid waste generated by the sulfuric acid industry and is considered environmentally hazardous. It contains abundant iron, such as Fe 2 O 3 and Fe 3 O 4 , and nonferrous metals, such as zinc, lead and copper. In order to try and recycle this material as a source of Fe units, preparation of direct reduction iron (DRI) using pyrite cinder was investigated by coal-based grate.

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.
2 KILN BASED SPONGE IRON PRODUCTION PROCESS Rotary kilns are found in many processes that involve processing of solids. This study focuses on sponge iron kiln based process. The chemical process involved in making sponge iron removes oxygen from iron ore by using a reducing agent in the form of non-coking coal [Patra et al, (2005)]. The.

Nov 12, 2020 Sponge iron process uses a rotary kiln for the reduction of high grade lump ores or pellets (Fig. 1). The feed is introduced together with reducing and de-sulphurizing agents (lime-stone or raw dolomite) into an inclined rotary kiln, heated counter current to the flow of hot gas and reduced to form sponge iron. Depending.
What is sponge iron Sponge iron, or DRI (Direct Reduced Iron), is essentially the next stage in the process chain after iron ore pellets. Unlike pellets, which still contain oxygen and must be further processed by the customers, sponge iron is pure, ready-made iron. Today's iron ore pellets must be reduced to iron before being used in.
Sponge iron produced by direct reduction is melted in an electric arc furnace, in which a pool of liquid metal is maintained. To ensure that liquid carbon-containing iron for forming the pool is available in adequate quantities and that the process can be carried out with the highest possible economy, the sponge iron is reacted in an electric arc furnace on a bath of liquid carbon-containing.
