Process 1 produces hydrogen from wind or marine energy at a remote location. The sponge iron and iron oxide remain onsite (static storage), and the iron oxide is used to absorb surplus hydrogen produced from electrolysis. The sponge iron is then used to release hydrogen when the power supplied by the renewable source is low.
The present paper proposes two energy integration options, Option-1 and Option-2, to compare power generation and preheating scheme in sponge iron process.Option-1 accounts power generation whereas in Option-2 preheating of feed material, slinger coal and kiln air is considered. These options utilize heat of waste gas …
The simplified process flow diagram (PFD) of an Indian sponge iron process, of 500 t/d production capacity, is shown in Fig. 1 along with industrial data. In this process, raw material admits to the kiln from the feed end and because of rotation as well as inclination inside the kiln feed moves to the discharge end.
This paper presents an approach to find the best modification in the coal-based sponge iron process with an aim to integrate energy in it. For this purpose, a few energy conservation cases are formulated by integrating unutilized energy present in possible areas of process flow sheet. When unutilized energy of the process is …
The metallic iron in this process is produced by the reduction of iron oxide below the fusion temperature of iron ore (1535 deg C) by utilizing carbonaceous material present in the non-coking coal. ... Equivalent metallization – Carbon content in sponge iron at a given degree of metallization is important. It has the capacity to remove oxygen ...
Sponge iron, also called direct reduced iron (DRI), is made from directly changing iron ore (in any form whatsoever) to iron by a cutback gas or carbon, produced from natural gas or coal. It is one of the many raw materials used in sponge iron. ... hence the name "Sponge Iron". The commercial process is a solid solution reduction, ...
The Sponge Iron Process (SIR) is a well-known technology for the production and purification of hydrogen. It consists of a cyclic process in which a feed gas, rich in carbon monoxide and hydrogen (e.g. syngas), is passed on an iron oxide (magnetite Fe3O4) at high temperature. Magnetite is reduced to wuestite (FeO) or iron while …

For producing the sponge iron through this process requires high grade of iron ore and non coking coal. Gas Based DRI / HBI. In this process route, iron oxides are converted to the DRI / HBI by using natural gas in a vertical shaft furnace. For steel producers, it is a preferred metallic, energy efficient and much more eco-friendly route.
Review of Sponge Iron Making Process Historical Development: Sponge iron was the main source of iron for many centuries before the blast furnace technology of iron making got developed. During that time sponge iron was developed in shallow hearths using charcoal which worked both as reductant and fuel.
