Iron Sponge Process an overview ScienceDirect Topics

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

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

The fold-processing of bog iron Museum of Cultural History

Crude iron with a high slag content. The extraction of crude bog iron, or the making of so-called sponge or bloom iron, was not a process we conducted as part of this project. The sponge iron was acquired from a group of people who have been working with iron extraction for years, Tom Haraldsen and Jens Jørgen Olesen being important contributors.

Iron Sponge Process Oil and Gas Separator

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.

Sponge Iron an overview ScienceDirect Topics

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

Extraction of Iron from its ores, Iron dressing, Reduction

Oct 23, 2018 Iron ( 26 Fe: (18 Ar), 4S 2, 3d 6 ) is found in the earth’s crust in the form of natural ores which contains different iron oxides mixed with impurities such as Silica (SiO 2), (Al 2 O 3), CaO, and MgO, and some harmful impurities such as s, p and As, The suitability of the ore in the extraction of iron economically depends on three factors which are:

Direct reduced iron process tec-science

Direct reduced iron (DRI) process. In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the so-called direct reduced iron (DRI) process (secondary route).The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.

Recent Progress in Titanium Extraction and Recycling

Jul 07, 2020 However, titanium sponge scrap with heavy iron contamination (generally several percent) cannot be utilized for titanium ingot production because the iron impurity in the ingot is difficult to dilute and homogenize. The direct removal of iron impurities from titanium products is impossible by the current industrial technology.
