Sponge iron reaction - Wikipedia

The sponge iron reaction (SIR) is a chemical process based on redox cycling of an iron-based contact mass, the first cycle is a conversion step between iron metal (Fe) and wuestite (FeO), the second cycle is a conversion step between wuestite (FeO) and magnetite (Fe 3 O 4). In appliion, the SIT is used in the reformer sponge iron cycle (RESC) in coination with a steam reforming unit.

Costs of Storing and Transporting Hydrogen - NREL

An analysis was performed to estimate the costs associated with storing and transporting hydrogen. These costs can be added to a hydrogen production cost to determine the total delivered cost of hydrogen. Storage methods analyzed included compressed gas, liquid hydrogen, metal hydride, and underground storage.

What are Conversion Costs? - Definition | Meaning | Example

Definition: A conversion cost is the amount incurred during the transformation of raw materials inventory into finished goods. In other words, this is the amount of direct labor and overhead costs that are required to turn raw materials into an actual product. What Does Conversion Cost Mean? Conversion costs consist of both overhead costs and direct labor.

Pig iron - Wikipedia

Pig iron is an intermediate product of the iron industry, also known as crude iron, which is first obtained from a smelting furnace in the form of oblong blocks. Pig iron has a very high carbon content, typically 3.8–4.7%, along with silica and other constituents of dross, which makes it very brittle and not useful directly as a material except for limited appliions.

What is Sponge Iron? (with pictures)

Jun 13, 2019· Sometimes known as direct-reduced iron, sponge iron is a product that is produced using iron ore.The iron ore is often in the form of pellets or lumps, and is subjected to a reduction process that is created by the use of a reducing gas that emits from coal or a natural gas source. This type of iron can be produced in several different types of furnaces, including coke or charcoal ovens,

Energy survey of the coal based sponge iron industry

Sponge iron is a metallic mass with honeyco structure. It is produced by direct reduction of iron ore in the presence of coal and air. Since last few years, sponge iron has emerged as an alternate raw material for steel making. The Indian Government has recognized sponge iron as a vital sector for growth of Indian steel industries.

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.
