Iron Sponge Process an overview ScienceDirect Topics

James G. Speight Ph.D., D.Sc., in Natural Gas (Second Edition), 2019 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).

Accretion Control in Sponge Iron Production Kiln using

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

Dec 17, 2020· These steel plants can replace polluting blast furnaces with a process that emits water vapor instead of CO2. On Nov. 23, LKAB announced that it intends to integrate forward in the steel supply chain and start producing "sponge iron" as a value-added product from its current pellet product, using the HYBRIT process.

Direct reduced iron Wikipedia

Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting

Heat is on for refractory, sponge iron, re-roller firms

Sponge iron is used by re-rollers to produce long steel such as thermo-mechanically treated (TMT) bars through induction furnaces. On their part, refractory products, which are heat and corrosion-resistant material used mainly in linings for furnaces and kilns, are mainly consumed by the steel sector, which accounts for about 75 per cent of domestic demand.
